Answers
Which statement best describes how Watson and Crick's model used other scientists' work to create a model of DNA? They used Chargaff's rule to determine that it contains ribose sugar. They used Franklin's photo to determine that DNA was a double helix. They used Levene's work to determine the number of base pairs in each strand. They used Nirenberg and Matthei's studies to determine that DNA is made of nucleotide
The statement best describes how Watson and Crick's model used other scientists' work to create a model of DNA.
A) They used Chargaff's rule to determine that it contains ribose sugar.
B)They used Franklin's photo to determine that DNA was a double helix.
How, explain your answer briefly?Watson and Crick used pieces of information available from different researchers such as Chargaff's rules and Franklin.
Chargaff had explained that the four kinds of nucleotides are present in a DNA molecule in such a manner that 2 types of nucleotides were always present in the same amounts and the other 2 types of nucleotides were also always present in the same amounts.
The first X-ray picture of DNA, created by Rosalind Franklin using a technique known as X-ray crystallography, which led to Watson and Crick's model of DNA. It explained the helical shape of the DNA molecule.
Thus, The correct statement is-They used Chargaff's rule to determine that it contains ribose sugar. They used Franklin's photo to determine that DNA was a double helix.

Explain how parts of a glucose molecule are used to make amino acids.
Answers
Glucose particles are ingested from gastrointestinal cells into the circulatory system. The circulation system then, at that point, conveys the glucose particles all through the body. Glucose enters every cell of the body and is involved by the cells mitochondrion as fuel.
After entering the Krebs cycle, the glucose forms different intermediates such as fumarate, succinyl coA, oxaloacetate, etc. These intermediates form the amino acids like asparagine, aspartate, valine, phenylalanine, etc.
How are amino acids formed from glucose?Glucose enters the cell and undergoes the glycolysis process to form pyruvic acid. Pyruvic acid enters the Krebs cycle and produces a variety of intermediates such as citrate, succinate, fumarate, oxaloacetate, and others.
These intermediates form amino acids. Oxaloacetate forms asparagine and aspartate. Fumarate makes valine and phenylalanine. Succinyl CoA makes isoleucine, valine, methionine, and threonine.
From pyruvate, different amino acids are formed, such as alanine, glycine, cysteine, serine, etc. From acetyl COA, acetoacetyl CoA is derived. This compound can make amino acids such as lysine, leucine, tyrosine, phenylalanine, etc.
Hence, in this way, different intermediates of glucose can make amino acids like valine, serine, etc.

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.
do you think that all living organisms show all of the characteristics of living organisms of all time?
Answers
Let’s explore this with an example,
The Characteristics of living things are:
Movement
sensitivity
respiration
reproduction
growth
excretion and nutrition
Human for example are living organisms, but we as organisms do not reproduce constantly or excrete constantly. The cells which make us up are constantly working but because we are multi cellular they are not considered the whole living organism.
If we were looking at a unicellular organism like salmonella bacteria, it might be a bit different. But even in bacteria they reproduce and excrete following a rhythm. They don’t do it constantly all the time, I hope that makes sense.

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.
Answers
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.
