Tropical savannas in East Africa have herds of zebra and wildebeest hoofed animals.
The zebra is a member of the equid family and is one of the most recognizable animals in the world. Its black and white stripes make it easily distinguishable from other animals, and it is found in a variety of ecosystems across Africa. Zebras are very social animals, living in large herds of up to several hundred individuals. They feed on grass and other vegetation, and are mostly active in the early morning and late afternoon.
The wildebeest is also a grazing mammal, but from the bovidae family. It is larger than the zebra and has a distinctive curved horn on its head. Wildebeest are highly social animals, often traveling in large herds of up to several hundred individuals. They are also mainly active during the early morning and late afternoon, and feed on grass and other vegetation.
The relationship between zebra and wildebeest is one of mutual benefit. The zebra’s stripes help camouflage it from predators, while the wildebeest’s curved horns are used to defend itself and the herd. Together, they can also provide better protection against predators by forming a large herd. In addition, the two species of hoofed animals help each other to find food and water, and they even graze in the same areas.

In RNA editing spliceosomes change the base sequence of the primary transcript and therefore the protein for which it codes. a combination of spliceosomes and enzymes creates different primary RNA transcripts from the same DNA sequence. different spliceosomes in different cells create different RNA sequences from the same primary transcript. enzymes change the base sequence of the primary transcript and therefore the protein for which it codes. microRNAs in different cells create different primary RNA transcripts from the same DNA sequence.
Answer:
enzymes change the base sequence of the primary transcript and therefore the protein for which it codes.
Explanation:
RNA editing refers to the post-transcriptional mechanisms by which nucleotide modifications are introduced into an RNA chain. The RNA editing processes exclude modifications produced during RNA splicing and polyadenylation. For example, deamination is an RNA editing mechanism by which an amine group from cytidine is removed by specific cytidine deaminase enzymes, thereby resulting in uridine (C to U).
Write a claim evidence and reasoning on Do trees change the composition of the atmosphere around us?
Answer:
Evidence: Trees absorb carbon dioxide from the atmosphere during the process of photosynthesis, and release oxygen as a byproduct. In this way, trees play a vital role in the global carbon cycle, and can help to mitigate the negative impacts of human activities that contribute to the increase of atmospheric carbon dioxide, such as the burning of fossil fuels.
Reasoning: The evidence provided demonstrates that trees have a direct effect on the composition of the atmosphere through their role in the carbon cycle. By absorbing carbon dioxide and releasing oxygen, trees can help to balance the levels of these gases in the atmosphere, and contribute to the overall health of the planet. The fact that trees have this ability suggests that they have the power to change the composition of the atmosphere around us.
Which evidence causes most scientists to believe that seafloor
spreading occurs at the mid-Atlantic Ridge?
А
Oceanic crust is oldest at the ridge.
B
Large sedimentary folds exist in the mantle near the ridge.
Oceanic crust on both sides of the ridge is less dense than
continental crust.
D
Oceanic crust on both sides of the ridge shows matching
patterns of reversed and normal magnetic polarity.
Answer:
Oceanic crusts on both sides of the ridge shows matching patterns of reversed and normal magnetic polarity.
Explanation:
Mid-Atlantic Ridge is a collection of mountains that settle at the bottom of the ocean. These mountains are the result of the movement of the plates. The breakdown of these mountains was very important to give truth to the theory that defended the existence of the expansion of the ocean floor and continental drift. That's because by looking at the mid-Atlantic Ridge, scientists were able to see that the oceanic crusts on both sides of the mid-Atlantic Ridge had patterns corresponding to normal and reverse magnetic polarity. This was the basis for perceiving the movement of the ocean's bottom in random directions.
How do you get the macromolecules in your body?
Answer:
explanation
Explanation:
Food provides the body with the nutrients it needs to survive. Many of these critical nutrients are biological macromolecules, or large molecules, necessary for life. These macromolecules (polymers) are built from different combinations of smaller organic molecules (monomers).
What is meant by this statement: “Mutation is random, but natural selection is not random.”
Environment-related factors are thought to affect the rate of mutation but not typically the direction of mutation.
What is Mutation?Exposure to dangerous chemicals may speed up the rate of mutation, but it won't result in more changes that make the organism immune to those toxins.
Many mutations are in reality "random," according to tests, and did not happen because the organism was put in a setting where the mutation would be advantageous.
Esther and Joshua Lederberg found that many of these mutations for antibiotic resistance were already present in the population in 1952, even before the population had been exposed to the antibiotic.

The cell cycle is an organized series of processes that take place in a cell before cell division.
What is Cell cycle?The cell cycle is a four-stage procedure in which the cell enlarges (gap 1, or G1), copies its DNA (synthesis, or S), gets ready to divide (gap 2, or G2), and splits (gap 4, or S).
Interphase, which accounts for the time between cell divisions, is made up of the stages G1, S, and G2. A cell "decides" whether to enter the cell cycle and divide based on the stimulatory and inhibitory signals it receives.
Growth factors, growth factor receptors, signal transducers, and nuclear regulatory proteins are the four groups that can be used to categorize the proteins that are involved in promoting cell division.

What phenomenon leads to calico pigmentation in female cats?
In cats, the genes for coat pigmentation are X-linked, resulting in an orange or black coat color depending on which copy of the X chromosome each cell has activated. X inactivation occurs only in cells with multiple X chromosomes. This characterize why almost all calico cats are female.
Known for their distinctive black, orange, and white coat patches, the calico cat is an example of a genetic process known as "lionization." Because calico cats have a genetic condition called spotting. Mottled animals have white skin or patches of white fur. This is controlled by genes that affect the ability of skin cells to produce the pigments responsible for color.

What assumption do we make about an isolated bacterial colony that formed on an agar plate?
When an isolated bacterial colony is discovered on an agar plate, there are a few assumptions that are typically made.
Firstly, it is assumed that the bacteria are a single species, which means that all of the bacteria in the colony are genetically related. This allows scientists to identify the bacteria by its unique characteristics, such as its color and size. Secondly, it is assumed that the bacteria are capable of reproducing, since it is only possible for the colony to form if the bacteria are able to divide and multiply. Lastly, it is assumed that the bacteria are not contaminated with any other microorganisms, since the bacteria need to be isolated in order to form a colony.
These assumptions allow scientists to accurately identify the bacteria and gain a better understanding of its characteristics. This knowledge can then be used to further research and study the bacteria, as well as develop treatments or vaccines if necessary. Therefore, these assumptions are essential in understanding the biology of the bacteria and its potential implications on human health.

Screens out harmful radiation
Answer:
Explanation:
With the arrival of warm summer weather, states have started to relax their COVID-19 stay-at-home orders. Excited to spend time with family and friends, people are now planning vacations, with one destination remaining a popular choice for many: the beach. However, extra time spent soaking up the sun increases our exposure to harmful ultraviolet (UV) radiation and raises our risk for developing skin cancer.
July is UV Safety Month. We know that one of the best ways to practice UV safety is to wear sunscreen every day. To help you choose and correctly use the best product for your needs, review the nine facts about sunscreen listed below.
Fact #1: Broad Spectrum Sunscreens are Best
UV radiation from the sun includes two types of harmful rays:
Ultraviolet A (UVA) Rays: Most common; cause premature aging of the skin (e.g., wrinkles)
Ultraviolet B (UVB) Rays: Most dangerous; cause sunburns
Overexposure to both types of rays can cause skin cancer. Sunscreens labeled as “broad spectrum” help protect against the effects of both UVA and UVB rays.
Fact #2: Aim for a Sunscreen with at Least 30 SPF
A sunscreen’s sun protection factor (SPF) indicates how much protection the product offers against UV radiation. Sunscreens with an SPF of at least 30 block 97 percent of the sun’s rays.
Fact #3: No Sunscreen is Waterproof or Sweat Proof
Manufacturers can no longer advertise sunscreens as waterproof or sweat proof. Instead, products are now labeled:
Water Resistant: Effective for up to 40 minutes in water
Very Water Resistant: Effective for up to 80 minutes in water
The AAD recommends reapplying sunscreen every two hours, after getting out of the water, or after sweating.
Fact #4: Children Under Six (6) Months Typically Should Not Wear Sunscreen
Infant skin is more sensitive than adult skin. To protect infants younger than six months, the AAD recommends keeping them in the shade as much as possible; dressing them in protective clothing, such as long-sleeved shirts, pants, and a wide-brimmed hat; and making sure they stay hydrated. If you are still concerned about sun exposure, ask your pediatrician if he/she recommends sunscreen.
Fact #5: Sunscreen is Only One Tool in Your UV Safety Toolbox
There are many ways to reduce your exposure to UV radiation. Experts recommend combining sunscreen use with wearing protective clothing, staying in the shade when possible, and avoiding outdoor activities when the sun is most intense.
Fact #6: Use “Teaspoon and Shot Glass Rule” to Determine How Much Sunscreen to Apply
Many people do not apply enough screen. The “Teaspoon and Shot Glass Rule” recommends using one teaspoon of sunscreen to cover the face and neck, and enough sunscreen to fill a shot glass — approximately one ounce — to cover all other exposed areas on the body.
Fact #7: Sunscreen Expires
According to the AAD, the FDA requires all sunscreens to retain their original strength for at least three years. Many sunscreens include an expiration date printed on the label. Visible changes in color or consistency can also indicate that it is time to dispose of the product.
Fact #8: Spray-On Sunscreens Are Convenient, But Not Always Effective
The AAD explains that current FDA regulations on testing and standardization do not apply to spray-on sunscreens. Individuals who want to use spray-on sunscreen should make sure to use an adequate amount, rubbing it in to thoroughly cover all areas of exposed skin.
Fact #9: Sunscreen is Safe to Use
Some recent news stories have called into question the safety of the ingredients used in sunscreens, but sunscreen remains completely safe to use and is recommended by all health care professionals. Read more about this in our blog post titled “Is Sunscreen Safe?”
