Trait formation due to behaviours, Thus, option "D" is correct.
What has most likely caused the variation in forelimbs?It is obvious to see that the three animals, cat, whale, and bat, have the same basic structure of their forelimbs, but also that they have developed differently and have taken a new shape. The reason for this is a trait formation due to behaviour.
The cat's ancestors were terrestrial, and the cats have remained terrestrial, walking on their four legs, and having the same shape and function as their ancestors.
The whales had similar forelimbs, but their ancestors started to move more and more in water. As they did, they needed more muscle power, but also greater width of the forelimb so that they can move more easily and more efficiently in the water.
This behaviour has gradually resulted in a flat, strong, peddle-like forelimb. The bat too had similar forelimbs to that of the cat, but its ancestors started to try to fly.
The process was gradual, and it started with jumping, then longer jumps, development of skin between the fingers, and elongation of the fingers, thus providing more area for the development of wider skin area. This has resulted in developing a light, wide, skin-dominated forelimb with elongated fingers, providing flight for the bat.
Thus, option "D" is correct.

You will write an argumentative essay to the “Bill and Melinda Gates Foundation” to convince them to support the use of genetically modified organisms in agricultural development and to support your team in developing the transgenic strain, knowing that this organization can provide the needed funding for your project.
The word count of your essay should be between 300 and 750.
Your essay should include at least 10 keywords from table 2.
Your essay will discuss how the new strain of the genetically modified plant will contribute to eradicating disease by using appropriate scientific methods that take into consideration any possible adverse health effects and environmental concerns (such as new potential allergies, herbicide-resistant weeds, and biodiversity issues for replacing other strains). It will also discuss why community acceptance of the new strain is important as a sustainable long-term solution as opposed to supplements or other food additives.
The purpose of your essay is to establish a stance on the urgency of the new strain issue by providing reasons and supporting evidence. When you’re writing a persuasive essay, you need more than just an opinion to make your voice heard. Even the strongest stance won’t be compelling if it’s not structured properly and reinforced with solid reasoning and evidence. Your essay needs to be well written and should include the following 4 elements:
1. Introductory paragraph:
The first paragraph of your essay should outline the topic, provide background information necessary to understand your argument, outline the evidence you will present and states your thesis.
2. The thesis statement:
This part of your essay is a concise, one-sentence summary of your main point and claim.
3. Body paragraph:
You will explain the reasons why you support your thesis. You can discuss more than one idea or piece of evidence that clearly and concisely explain why the reader should agree with your position.
This is where you will back up your claims with examples, research, statistics, studies, and scientific evidence based on your knowledge in genetics and your answers in the graphic organizer.
Address opposing points of view and disprove them or explain why you disagree with them. Presenting facts and considering the topic from every angle adds credibility and will help you gain the reader’s trust.
4. Conclusion:
One paragraph that restates your thesis and summarizes all of the arguments made in your body paragraphs. Rather than introducing new facts or more arguments, a good conclusion will appeal to a reader’s emotions. In some cases, writers will use a personal anecdote explaining how the topic personally affects them.
Some of the points that you can use in your argumentative essay to support the use of genetically modified organisms in agricultural development are:
They are tolerant to herbicidesThey help in weed controlThey help maintain soil healthThey lead to a lower cost of laborThere is a greater nutrient composition Increase in food quality. What is an Argumentative Essay?This refers to the type of essay that makes use of logical arguments in order to convince or persuade a person about a point of view.
Hence, we can see that based on the argumentative essay prompt, you would need to show the good reasons why the use of genetically modified organisms in agricultural development should be supported and the above points should come in handy.

3. What are the functions of the macromolecule you explored?
4. Summarize the relationship between the structure of your subunit and the function of the macromolecule it forms.
Answer:
1. Macromolecules are typically BIG molecules, and they truly are the building blocks of cells. Macromolecules are generally built by combining many single units, or monomers, into larger units, called polymers.
2.polymers which are long chains of subunits called monomers.
3.Gigantic molecules, called macromolecules, populate a cell and provide it with important functions for life. For example, macromolecules provide structural support, a source of stored fuel, the ability to store and retrieve genetic information, and the ability to speed biochemical reactions.
4.Polymers are macromolecules, but not all macromolecules are polymers. The main difference between a polymer and a macromolecule is that polymers contain repeating units that represent monomers whereas not all macromolecules have a monomer in their structure

Answer:
The most closely related are amphibians and reptiles.
The least related are amphibians and mammals
Explanation:
Amphibians broke off from reptiles, birds, and mammals around 260 millions years ago and next up are the reptiles which broke off around 225 million years ago. So they are the most closely related
Mammals are the last to break off, around 200 million years ago. So they are the least related to amphibians.

Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages.In an experiment, a snail was observed to have moved a distance of 0.5 meters in 2 hours. What rate of movement was observed in this experiment?
The rate of movement was observed in this experiment as 0.25 m/ hour.
How, explain your answer?A rate of movement is essentially a speed measurement, where you divide the distance crossed from point A to point B by the time it took to do it.
o, we know the snail moved a total distance of 0.5 meters. that's our distance crossed.
We know that took 2 hours. so we just have to calculate that:
0.5 meters / 2 hours = 0.25 m/hour

Energy from ATP
Explanation:
ATP, or adenosine triphosphate, is a chemical that transports energy within cells. It is the cell's primary source of energy, and it is produced via photophosphorylation (adding a phosphate group to a molecule using light energy), cellular respiration, and fermentation. ATP is used by all living organisms. It is employed in signal transduction pathways for cell communication and is integrated into deoxyribonucleic acid (DNA) during DNA synthesis, in addition to being an energy source.
