NOT a test variable they might want to investigate?
A. resulting sunburns
B. frequency of application
C. length of exposure to the sun
D. numerical strength of the sunscreen

Answers

Answer 1
Hi there! Based on the question you provided, it seems like Marley's mom's company is trying to test the effectiveness of its new sunscreen products. To answer your question, they might want to investigate all of the test variables mentioned except for the numerical strength of the sunscreen (option D). This is because the strength of the sunscreen is already known and should not be changed during the testing process.

Option A, resulting sunburns, would be a good variable to investigate as it measures the effectiveness of the sunscreen in preventing sunburns. Option B, frequency of application, would also be important to investigate as it can determine how often the sunscreen needs to be applied for optimal protection. Option C, length of exposure to the sun, would also be a significant variable to investigate as it can determine how long the sunscreen can protect the skin from sun damage.

I hope that helps! Let me know if you have any otherquestions.

Answers

Based on the endosymbiotic theory, A: Prokaryotic organisms engulfed* a virus and developed a symbiotic relationship which led to the evolution of organelles such as mitochondria and chloroplasts.

The endosymbiotic theory proposes that eukaryotes evolved from a symbiotic relationship between a prokaryote and another prokaryote. Evidence for this theory includes the discovery of small, membrane-bound organelles within eukaryotic cells that are similar in structure and function to prokaryotic cells. This suggests that these organelles may have originated from engulfed prokaryotes. One example of this is the endosymbiotic theory of the origin of plastids, which proposes that chloroplasts in plant cells and other organisms originated from engulfed cyanobacteria. Therefore, option A is supported by evidence for how eukaryotes evolved.

Why does an action potential travel in one direction down an axon?.

Answers

An action potential is an electrical signal that travels down the axon of a neuron. One of the key features of an action potential is that it travels in one direction only, from the cell body of the neuron to its axon terminal.

This directional flow of the action potential is due to the refractory period of the neuron. After an action potential is fired, the neuron enters a brief refractory period during which it is unable to generate another action potential in the same direction.

This refractory period ensures that the action potential moves only in one direction, preventing the signal from moving backward and interfering with other signals in the nervous system.

For a sequence of mrna, how many reading frames are possible?.

Answers

For a sequence of mRNA, there are three reading frames possible.

The genetic information in DNA is transcribed into mRNA, which is then translated into proteins. The mRNA sequence is read in groups of three nucleotides called codons.

Each codon specifies a particular amino acid to be added to the growing polypeptide chain during translation. However, the reading frame, or the grouping of nucleotides into codons, can be shifted by one or two nucleotides, resulting in a different amino acid sequence.

Thus, for a given mRNA sequence, there are three possible reading frames, one for each possible starting position of the codon triplets. The correct reading frame is established by the start codon, AUG, which codes for the amino acid methionine and signals the beginning of translation. If the reading frame is shifted, the resulting protein may be completely different, leading to a frameshift mutation.

Therefore, the three possible reading frames of mRNA are crucial for the accurate translation of genetic information into proteins.

The trait of polydactylism has a dominant inheritance pattern. Individuals only need 1 copy of the allele for polydactylism to show the trait of having 6 fingers. With albinism two unaffected (pigmented) individuals can have an affected child with albinism.

Explain why two individuals unaffected by polydactylism cannot have a child with polydactylism? Use the alleles when describing the genotypes of individuals in your explanation:
D- affected by polydactylism and d- unaffected by polydactylism

Answers

Two individuals unaffected by polydactylism cannot have a child with polydactylism because they do not carry any copies of the dominant allele (D) for polydactylism.

To express the trait, an individual only needs to inherit one copy of the dominant allele. The unaffected individuals can only pass on the recessive allele (d) to their offspring. Therefore, the child will not receive a dominant allele for polydactylism from either parent, making it impossible for them to express the trait.

In other words, if both parents are homozygous recessive (dd) for polydactylism, all their offspring will be heterozygous (Dd) carriers of the recessive allele. Even if one of the parents is heterozygous (Dd), the probability of the child receiving two recessive alleles (dd) is 25%, making it impossible for the child to express the dominant trait of polydactylism. Therefore, for a child to express the dominant trait of polydactylism, at least one of the parents must have the dominant allele (D).

A cell with 89% particles is placed in a solution with 75% particles. The water will flow from the solution into the cell.

This is because the solution has a higher concentration of particles than the cell does. When particles are placed in a solution with a higher concentration of particles, the water molecules tend to move from the dilute side (the cell) to the more concentrated side (the solution).

This movement of water is known as osmosis. Osmosis occurs when two solutions at different concentrations are separated by a semipermeable membrane. In this case, the cell has a lower concentration of particles compared to the solution.

Clades refer to the evolutionary groups that share a common ancestor. In a phylogenetic tree, clades are represented by branches that split into smaller sub-branches as you move further down the tree. Clades 2 and 3 are the two major groups of birds and dinosaurs, and they share a common ancestor.

Birds belong to the clade 2, which includes theropod dinosaurs. These were a group of bipedal dinosaurs that included the famous Tyrannosaurus rex and Velociraptor. As a result, birds share many characteristics with their dinosaur ancestors, such as feathers, hollow bones, and the presence of a wishbone.

Clade 3, on the other hand, includes sauropod dinosaurs such as the Brachiosaurus and Diplodocus. These were herbivorous dinosaurs that had long necks and tails. Unlike birds, they went extinct about 66 million years ago.

Therefore, based on the evolutionary relationships shown by the phylogenetic tree, birds are considered dinosaurs as they evolved from a common ancestor shared by the theropod dinosaurs.

On Principles of Evolution:

The two methods used together to demonstrate the Earth is at least 3.8 billion years old are radiometric dating and stratigraphy. Known for Pangaea, smaller continents and current configuration respectivelyImportance of the environment in shaping organisms and lack of evidenceFalse Subject to natural selection, genetic drift, gene flow, and mutation.Passed to offspring naturally and the other is done by humans.

What are the principles of evolution based on?

Radiometric dating involves using the decay of radioactive isotopes to determine the age of rocks and fossils, while stratigraphy involves the study of rock layers and the order in which they were deposited.

During the Paleozoic era, the continents were clustered together as one large landmass known as Pangaea. During the Mesozoic era, Pangaea began to break apart into smaller continents, and by the end of the era, the continents were in positions similar to their current locations. During the Cenozoic era, the continents continued to move and drift apart, forming the modern configuration we see today.

Lamarck's theory of evolution, also known as the theory of inheritance of acquired characteristics, states that organisms can pass on traits acquired during their lifetime to their offspring. The strengths of this theory are that it was one of the first to propose a mechanism for evolution, and it emphasized the importance of the environment in shaping organisms. However, the theory has several weaknesses, such as the lack of evidence supporting the idea that acquired traits can be passed on genetically, and the fact that some traits are determined by genes rather than environmental factors.

False. Dominant alleles do not always increase in frequency because their success is dependent on the environment and the fitness of individuals carrying the allele. If the environment changes, a once-dominant allele may become detrimental and decrease in frequency.

Populations evolve because they are subject to natural selection, genetic drift, gene flow, and mutation. These factors can cause changes in allele frequencies over time, leading to the evolution of the population. Individuals, on the other hand, do not evolve because they cannot change their genetic makeup during their lifetime.

Natural selection is the process by which organisms with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. It is a natural process that occurs without human intervention. Artificial selection, on the other hand, is the process by which humans intentionally breed plants or animals for specific traits. Humans selectively choose individuals with desirable traits to mate and produce offspring with those traits.

Answers

Bears are solitary animals and live alone for several reasons. One of these reasons is that there are not enough resources in the environment to support multiple bears.

The food available is limited, and so each bear has to compete to find enough to survive. The limited resources also mean that bears must travel long distances in order to find enough food and shelter. Living alone allows them to cover more ground, and also reduces competition for food and shelter.

Additionally, living alone means that bears are less exposed to potential threats from other animals, reducing their risk of injury or death. Finally, bears have to be able to find mates in order to reproduce, and living alone allows them to have more options for mates. All of these factors contribute to why bears are solitary animals.

Seals and polar bears share a predator-prey relationship because polar bears eat seals. In colder regions where polar bears live, ice caps have melted as a result of climate change. This change has made it harder for polar bears to effectively chase seals as they depend on the ice to chase and travel. Polar bears are forced to swim for longer distances as a result of the loss of sea ice, which results in an increase in their energy expenditure and a decline in their overall health. Because they are unable to procure sufficient food to sustain themselves, this circumstance will result in a decrease in the population of polar bears.

Answer:

A. The kittens inherited different genes for fur color from their parents.

Explanation:

This because the genotype of fur color is from parents, your literal genetic makeup. While phenotype is influenced by your surroundings.

which of the following is an example of transmembrane transport? group of answer choices transport of a protein from the cytosol to the nucleus transport of a protein from the cytosol to the er transport of a protein from the golgi apparatus to the endosomes transport of a protein from the er to the golgi apparatus all of the above

Answers

In the context of transmembrane transport, the correct answer among the given choices would be transport of a protein from the cytosol to the endoplasmic reticulum (ER).

Transmembrane transport involves the movement of molecules, such as proteins, across a biological membrane. In this case, proteins are transported from the cytosol, where they are synthesized, to the ER, where they undergo further processing and modifications.

The other options do not represent transmembrane transport. Transport of a protein from the cytosol to the nucleus is an example of nuclear import, while transport between the ER and Golgi apparatus or from the Golgi apparatus to the endosomes represents intracellular vesicular trafficking.

These processes are distinct from transmembrane transport and involve different mechanisms and molecular machinery.

When cloning an organism, who will the clone be most similar to: body cell donor, egg cell donor, or surrogate mother? Why?

Answers

The clone will be most similar to the body cell donor. This is because the body cell donor provides the genetic material that is used in the cloning process to create the clone.

The egg cell donor's genetic material is replaced with the donor's body cell genetic material, and the surrogate mother only provides a host for the embryo to develop in. Therefore, the clone will be the most similar to the body cell donor since the clone will be made up of the donor's genetic material.

The clone will be an exact genetic replica of the body cell donor, and will have the same characteristics and traits, though it will not have the same experiences or life events as the donor.

Suppose a large airline wants to estimate its average number of unoccupied seats per flight over the past year. To accomplish this, the records of 300 flights are randomly selected and the number of unoccupied seats is noted for each of the sampled flights. The sample mean is 11. 3 seats and the sample standard deviation is 4. 3 seats. Required:Construct a 92% confidence interval for the population mean number of unoccupied seats per flight Based on information in the article, which best describes the difference between the child labor rates in Nepal and Mongolia?A.Child labor rates have increased in Mongolia since 1990, but decreased in Nepal since 1990.B.Child labor rates have increased in Mongolia since 1990, but stayed the same in Nepal since 1990.C.Child labor rates have increased in Nepal since 1990, but decreased in Mongolia since 1990.D.Child labor rates have increased in Nepal since 1990, but stayed the same in Mongolia since 1990.In 2000, there were 127 million children working in Asia. By 2004, that number had fallen to 122 million. Officials are pleased that child labor rates have dropped, but they say the decline isn't happening fast enough.Those numbers came from a recent report from the International Labor Organization (ILO). The report focused on South Asia, which includes Afghanistan, India, Pakistan, Bangladesh, Sri Lanka, and other nations. It concluded that despite the decrease in the number of working children ages five to 14, South Asia remains a child labor hot spot.The report discussed child labor in several nations and identified Nepal as one of the worst offenders. As of 2004, almost 40 percent of Nepalese children aged 10 to 14 were working. Many continue to do strenuous physical labor in mines, quarries, and carpet factories. Still, even in Nepal, child labor rates are declining; they had been near 50 percent in 1990.The Philippines has improved, but problems remain in some industries. Many Filipino children still work in fireworks production, deep-sea fishing, and mining. The country has a national action plan to change this."The [anti-child labor] laws are all there," said Filipino Undersecretary of Labor and Employment Manuel G. Imson. Imson says that the government is working with the police to enforce these laws.In some cases, child labor has emerged where it was previously nonexistent. There were few or no child laborers in Mongolia until 1990; today, up to 10,000 children there work in gold, coal, and mineral mines. Kh. Ganbaatar, executive director of the Mongolian Employers' Federation, blames the problem on economic changes as well as on natural disasters. Several years ago, winter storms killed millions of livestock. This made it harder for families to maintain their traditional herding way of life. Many of these families were forced to send their children to work.In fact, child labor often develops because area families cannot make ends meet and need extra income. In other cases, parents want to send their children to school but cannot afford the related fees."A large number of working poor means that we have a large number of people who are unable to support children [going] to school," said Panudda Boonpala, senior child labor specialist at the ILO.In August, government representatives from nearly 40 countries as well as workers' and employers' organizations attended an ILO conference. Topics on their agenda included migration, competitiveness, productivity, and youth employment (child labor). At a session on youth employment, participants watched a video that showed children working at a gold mine in Mongolia.The ILO says that it will try to end some of the worst forms of child labor within 10 years. Its officials point out that attitudes about working children have changed in Asia. This is contributing to the reduction in child labor rates."I think 10 years ago there was lots of denial," Panudda said. Still, she said, nations will not be able to end child labor unless they are willing to put a lot of effort and funding into the fight against it.
