Answer: Answer is below <3
Explanation:
1. Get under the desks. If your not under a table or under something that’s sturdy, something might fall on top of you and damage something really bad.
2. Cover your head. What ever you do, you DO NOT want your head to be hit in an earthquake, it could lead to a concussion or even death.
3. Grab onto something. If you don’t grab onto something to keep yourself in place, you might just slide around and bump into stuff. Maybe even knocking stuff over onto your head. So, be sure to grab on.
4. Stay away from anything that’s heavy and that can fall on you. If you’re not away from let’s say.. a bookshelf it could easily fall on you and possibly kill you.
5. Don’t panic. Thankfully, earthquakes don’t last too long so just try your best to stay safe and away from any falling bookshelves or anything else heavy.
How do we know UV light has energy?
Describe what happens when it is absorbed by ozone and melanin.
Please help
90 points
All radiation is a form of energy, most of which is invisible to the human eye. UV radiation is only one form of radiation and it is measured on a scientific scale called the electromagnetic (EM) spectrum.
Ozone: When an ozone molecule absorbs even low-energy ultraviolet radiation, it splits into an ordinary oxygen molecule and a free oxygen atom.
Melanin: Melanin absorbs the dangerous UV rays that can do serious skin damage. This is the process that gives you a tan. A tan is a sign that your skin is trying to keep UV rays from damaging your skin.
Elaborate on two methods of microbial control that are essential for reducing the likelihood of foodborne illnesses? Are these methods applied worldwide?. What are some infections that we see, more so, when these methods are not used or not properly used?
Answer:
There are several methods of microbial control that are used to reduce the likelihood of foodborne illnesses, but two essential methods are thermal processing and chemical disinfection.
Thermal Processing: This is a method of microbial control that uses high temperatures to kill harmful bacteria, viruses, and other microorganisms in food. The most common form of thermal processing is heat treatment, which involves cooking food at a high temperature for a specific period of time. The heat destroys the microorganisms that can cause illness, such as Salmonella, Listeria, and E. coli. Pasteurization is another form of thermal processing that is used to kill harmful bacteria in milk, juices, and other beverages. This method involves heating the liquid to a specific temperature for a specific period of time to kill the microorganisms.
Chemical Disinfection: This method involves the use of chemicals to kill microorganisms on surfaces, utensils, and equipment used in food preparation. Common disinfectants used in food industry include chlorine-based compounds, iodophors, and quaternary ammonium compounds. These disinfectants are effective against a wide range of microorganisms, including bacteria, viruses, and fungi.
Both thermal processing and chemical disinfection are widely used worldwide in the food industry to prevent the spread of foodborne illnesses. However, there are still instances where these methods are not used or not properly used, leading to outbreaks of foodborne illnesses.
Some examples of infections that are more likely to occur when these methods are not used or not properly used include:
Salmonella Infections: This type of infection is commonly associated with undercooked or raw poultry, eggs, and meat. If these foods are not cooked to a sufficient temperature, the Salmonella bacteria may survive and cause illness.
Listeria Infections: Listeria bacteria can grow in refrigerated foods, such as deli meats and soft cheeses, if they are not properly stored and handled. This can lead to serious illness, especially in pregnant women and people with weakened immune systems.
In conclusion, thermal processing and chemical disinfection are essential methods of microbial control that help reduce the likelihood of foodborne illnesses. When these methods are not used or not properly used, it can lead to outbreaks of illnesses caused by bacteria such as Salmonella and Listeria. It is important for the food industry to continue to use these methods to ensure the safety of the food supply.

Explain natural selection using a difference between highland Tibetans and lowland Han.
Answer:
Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to their offspring. An example of natural selection can be seen in the difference between highland Tibetans and lowland Han in China.
Highland Tibetans have lived at high altitudes for thousands of years and have adapted to the low-oxygen environment. They have larger lung capacities, more efficient blood oxygen transport, and a higher red blood cell count compared to lowland Han. This adaptation has allowed Tibetans to live and thrive at high altitudes where the air is thin and oxygen is scarce. The ability to adapt to high altitudes is an advantageous trait that has been selected for over generations.
On the other hand, lowland Han have not lived at high altitudes for as long as Tibetans have, and thus have not developed the same adaptations. When lowland Han move to high altitudes, they often suffer from altitude sickness and other health problems due to the lack of oxygen. This is an example of natural selection at work, where the better-adapted population (Tibetans) have an advantage in their environment and are more likely to survive and pass on their advantageous traits to their offspring.
Natural selection is the process by which organisms that are better adapted to their surroundings live and reproduce, passing on their good characteristics to their offspring. The difference between highland Tibetans and lowland Han in China is an example of natural selection. Highland Tibetans have been living at high altitudes for thousands of years, adapting to the low-oxygen climate. When compared to lowland Han, they have bigger lung capacities, more efficient blood oxygen transport, and a higher red blood cell count. Tibetans have been able to live and grow at high altitudes where the air is thin and oxygen is short due to this adaptation. Adaptability to high altitudes is a helpful characteristic that has been selected for over generations. Lowland Han, on the other hand, have not lived at high altitudes for as long as Tibetans, and so have not evolved the same adaptations. When lowland Han migrate to high altitudes, they usually experience altitude sickness and other health issues due to a shortage of oxygen. This is an example of natural selection in action, where the better-adapted population (Tibetans) has an advantage in their environment and is more likely to live and pass on their good characteristics to their offspring.
A paleoanthropologist finds a fossilized skull with very large molars with thick enamel, relatively small canines, and small incisors. What might you hypothesize about the diet of this creature? (max 3 sentences)
Based on the characteristics of the fossilized skull, it can be hypothesized that the creature had a diet that consisted of tough and fibrous plant material, such as roots, stems, and leaves. The large molars with thick enamel would have been used for grinding and crushing these types of foods, while the small canines and incisors suggest a reduced emphasis on meat in their diet. Additionally, the lack of sharp incisors would suggest that the creature did not need to tear apart flesh or other tough materials.
Seafloor spreading and continential drift are believed to be caused by what?
Seafloor spreading and continental drift are believed to be caused by plate tectonics. Plate tectonics is the scientific theory that explains how the Earth's lithosphere is divided into a number of plates that move and interact with each other due to the underlying convective flow in the mantle. The movement of these plates can cause a variety of geological phenomena such as earthquakes, volcanic eruptions, and the creation of mountain ranges. Seafloor spreading is a process in which new oceanic crust is formed through volcanic activity at mid-ocean ridges, and continental drift is the movement of continental plates across the Earth's surface.
Attach your TABLE (Provided above showing the migration distances for the MW markers (1 kb ladder), PCR fragment, and vector, both digested and undigested. You should have calculated the sizes for each band you detected on your gel using the standard curve you generated from the MWM). Make sure these sizes are entered on the TABLE. Attach your log-linear graph with standard curve
1. How many bands did you detect in the lane with undigested plasmid? What size(s) were they? Explain each band. 2. How many bands did you detect in the plasmid cut with BamHI? Basing your answer on this result, how many sites are there in the plasmid? 3. Compare the insert digested with BamHI with the undigested insert: do you see a size difference? Explain. 4. Given the sizes of the vector and PCR product, what is the expected size of the plasmid constructed by ligating the two? Explain
There are 17 rings that still contain undigested plastic. Sizes range from 100 to 12000. The rings cover a range of three to twelve centimeters. They can grow to various sizes as a result of this.
To determine the number of bands detected in the lane with undigested plasmid, count the number of distinct bands observed on the gel. The size(s) of each band can be determined by comparing their migration distance to the molecular weight markers (MWM) that were run on the same gel. Each band represents a different sized fragment of DNA that is present in the plasmid sample. The explanation for each band would depend on the context of the experiment and the specific plasmid being analyzed.
To determine the number of bands detected in the plasmid cut with BamHI, count the number of distinct bands observed on the gel. The number of bands should correspond to the number of sites that the restriction enzyme BamHI recognizes and cuts within the plasmid. For example, if two bands are observed, this would indicate that BamHI recognizes and cuts at two specific sites in the plasmid.
To compare the insert digested with BamHI with the undigested insert, compare the sizes of the bands observed in each lane. If a size difference is observed, this would indicate that the BamHI digestion cleaved the insert at specific sites, resulting in fragments of a smaller size compared to the undigested insert. This would confirm that the insert contains BamHI recognition sites.
To calculate the expected size of the plasmid constructed by ligating the vector and PCR product, add the sizes of the vector and PCR product together. For example, if the vector is 4 kb and the PCR product is 2 kb, the expected size of the ligated plasmid would be 6 kb. This assumes that the vector and PCR product were both cut with compatible restriction enzymes, allowing for successful ligation.

The boundaries between Eons and Era’s are marked by huge _____________ events which can be seen in the fossil record.
Answer:
The boundaries between eons and eras are marked by huge geological events which can be seen in the fossil record. These events are often associated with mass extinctions, major changes in the Earth's climate or geology, or other significant shifts in the evolutionary history of life on Earth. For example, the boundary between the Precambrian eon and the Phanerozoic eon is marked by the appearance of hard-shelled organisms in the fossil record, while the boundary between the Mesozoic era and the Cenozoic era is marked by the mass extinction of the dinosaurs.
Explanation:
The geological time scale is divided into several major divisions, including eons, eras, periods, and epochs. These divisions are based on major events in the history of the Earth, such as the appearance or extinction of particular species, changes in climate, or major geological events like volcanic eruptions or asteroid impacts.
The boundaries between eons and eras are particularly significant because they represent major shifts in the evolutionary history of life on Earth. These shifts are often marked by mass extinctions, which occur when a large proportion of the Earth's species go extinct in a relatively short period of time. These extinctions can be caused by a variety of factors, such as changes in climate, geological activity, or the impact of a large asteroid or comet.
The fossil record provides evidence of these major events, allowing scientists to piece together the history of life on Earth and understand how different species have evolved and interacted with each other over time. By studying the fossil record and other geological evidence, scientists can gain insights into the processes that have shaped the Earth and its inhabitants over billions of years.

Compare and contrast how the circulatory system is important to obtaining raw
materials and excreting byproducts of cellular respiration.
The circulatory system plays an important role in both obtaining raw materials and excreting byproducts of cellular respiration.
What is cellular respiration?Cellular respiration is a metabolic process in which living organisms convert nutrients such as carbohydrates and proteins into energy. During this process, energy is released from the molecules and used to produce adenosine triphosphate (ATP) molecules.
Obtaining raw materials: The circulatory system is responsible for transporting oxygen and other essential molecules to cells, which are then used as fuel for cellular respiration. Oxygen is obtained from the lungs and is transported through the bloodstream to the cells. Nutrients, such as glucose and amino acids, are also transported via the circulatory system for the purpose of providing energy to cells.
Excreting byproducts: The circulatory system is also responsible for carrying away the byproducts of cellular respiration, such as carbon dioxide and other waste products. These byproducts are transported away from the cells, to be released as gas or excreted in the form of urine.
In summary, the circulatory system is essential to cellular respiration, as it facilitates the transport of both the raw materials and the byproducts. Without the circulatory system, cells would not be able to obtain the necessary materials for respiration, nor would they be able to expel the waste products in an efficient manner.

Why can’t all animals perform photosynthesis?
What are two examples of photosynthesizing animals?
How do these animals carry out the process of photosynthesis?
Are they born to carry out photosynthesis or do they develop the ability over their lifespan?
Do these animals eat in addition to carrying out photosynthesis?
What are the similarities and differences between these animals?
Why is the ability to perform photosynthesis an advantage to these animals?
How does the discovery of the animals further scientists’ understanding of the relationships between plants and animals?
Explanation:
All animals lack the specialized structures necessary for photosynthesis, such as chloroplasts and specialized pigments. Therefore, they cannot perform photosynthesis like plants and certain algae.
There are no known examples of photosynthesizing animals. While there have been a few reports in the past of animals supposedly capable of photosynthesis, further research has shown that these claims were not well-substantiated.
As there are no known examples of photosynthesizing animals, this question is not applicable.
Photosynthesizing animals do not exist, so they are not born or develop the ability to perform photosynthesis.
This question is not applicable, as photosynthesizing animals do not exist.
As previously mentioned, photosynthesizing animals do not exist.
The ability to perform photosynthesis would be a significant advantage to animals as it would allow them to generate their food from sunlight and would reduce their dependence on external food sources. This would be particularly advantageous in areas with limited food availability.
As there are no known examples of photosynthesizing animals, the discovery of such an animal would have significant implications for our understanding of the relationships between plants and animals. It would suggest that there may be more complex and intertwined relationships between these groups of organisms than we previously thought. However, as of yet, there is no evidence that photosynthesizing animals exist.
6. Assume that eye color in humans is controlled by a single pair of genes of which

(c) What are the expected proportions of eye colors among the offspring of a mat-
ing between two brown-eyed individuals who each had one parent that was blus-
eyed?
Explanation:
(a) The genotype of the brown-eyed individual would be Bb, since they have a dominant B allele for brown eyes and a recessive b allele for blue eyes. The blue-eyed individual would have a genotype of bb.
(b) The offspring of the Bb x bb mating would have a 50% chance of inheriting the b allele from the Bb parent and a 50% chance of inheriting the b allele from the bb parent. Therefore, the expected proportions of the two eye colors among further offspring would be 50% brown-eyed and 50% blue-eyed.
(c) Each of the brown-eyed individuals who had one parent that was blue-eyed would be heterozygous Bb. Therefore, the expected proportions of the offspring's genotypes would be 25% BB, 50% Bb, and 25% bb. Since the B allele is dominant, the expected proportions of eye colors among their offspring would be 75% brown-eyed and 25% blue-eyed.

Describe Genotype?Genotype is the genetic makeup of an individual organism, which includes all of the genes that an organism carries in its DNA. It represents the complete set of inherited instructions that determine the physical and behavioral traits of an organism.
Genotype is typically described using letters that represent different versions of a gene called alleles. Each individual has two alleles for each gene, one inherited from each parent. If the two alleles are the same, the individual is said to be homozygous for that gene, whereas if the two alleles are different, the individual is heterozygous.
The dominant allele is expressed when present in either the homozygous or heterozygous state, while the recessive allele is only expressed when present in the homozygous state.
1. a. Heterozygous: Ff
b. Homozygous Dominant: FF
c. Homozygous Recessive: ff
2. In incomplete dominance, neither allele is completely dominant or recessive, and the heterozygous phenotype is an intermediate between the homozygous dominant and homozygous recessive phenotypes.

I need help the assignment is an savvas assignment it’s called “the genetic code
Answer: split them into section 3 letters in a section. In the 2nd section n the left you would notice AUG that’s your start code, circle that and at the very end circle UAG that’s a Stop code

Experiment I: Effect of Different Substrates on the Rate of Enzyme Reaction
Consider the structures of the other substrates tested. Suggest reasons why only one elicited a reaction with the enzyme. Think about the active site of the enzyme
The other substrates did not fit the active site of the enzyme, resulting in no reaction.
The reason why only one substrate elicited a reaction with the enzyme could be due to the fact that the other substrates did not fit the active site of the enzyme. Enzymes are highly specific in their action, and they can only catalyze reactions with molecules that fit their active sites.
In the case of the experiment, the enzyme may have a specific active site that only allows the structure of the substrate that elicited a reaction to fit into it. The other substrates may have different structures that prevent them from binding to the enzyme's active site, and as a result, no reaction was observed.
It is also possible that the other substrates were not the optimal substrate for the enzyme, and therefore, the reaction rate was low or non-existent. Enzymes often have a preferred substrate that they can catalyze the reaction with the most efficiency. Overall, the selectivity of the enzyme's active site is likely the reason why only one substrate elicited a reaction with the enzyme in the experiment.

why do traits vary, and why do they vary even between parents and offspring and among sibilings
Answer: Traits vary because of recessive and dominant traits
Explanation: When an offspring inherits traits, it receives traits from both its parents. For example, we can use the gene for brown or green eyes.
Brown is a dominant trait (meaning organisms only need one of its genes in order to have brown eyes) and green is a recessive trait (meaning organisms must have two green eye genes in order to inherit green eyes).
We can make BB be brown eyes with two brown eye genes, Bb be brown eyes with one brown eye gene and one green eye gene, and bb be green eyes with two green eye genes.
Say both parents have Bb, and the offspring can inherit one gene from each parent. The possibilities for the offspring gene would be BB, Bb, and bb. Therefore demonstrating how it is possible for an offspring to have different traits than their parents or siblings (a sibling could inherit bb and another BB, so one is green-eyed and the other brown-eyed.)
Obviously in reality there are many more factors that play into genes and much more diversity, however, this method pretty much explains the Punnet square method.
What's The answer ?????
Ferns
Explanation:
"Ferns are a natural inhabitant of shady areas"
Ferns live in shady areas. So do Oxalis but they do not live in a lot of shade. So Ferns.
