Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN

Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

<em>In any one species, the amount of adenine closely approximates that of thymine. </em>
<em>In any one species, the amount of guanine closely approximates that of cytosine. </em>
<em>The amounts of A, T, G, and C in DNA varies from species to species. </em>

<em>(options A, B and D)</em>

Explanation:

Organizing the data has to:

<u>Source of DNA A T G C </u>

Streptococcus 29.8 31.6 20.5 18.0

Yeast 31.3 32.9 18.7 17.1

Herring 27.8 27.5 22.2 22.6

Human 30.9 29.4 19.9 19.8

E. Coli 24.7 23.6 26.0 25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.

What happens to an enzyme when it performs its function? What does this mean about enzyme molecules??

ratelena [41]

1. Enzyme interacts with substrate
. 2. Enzyme may undergo a conformational change to capture the substrate ("induced fit" model)
3. Enzyme-substrate complex may undergo several changes to form the product(s).
4. The product(s) are released
. 5. The enzyme returns to its original form. It is then ready to do the cycle all over again.

You have been assigned to care for Jim. He is 29 years old and has been diagnosed with Schizophrenia. Jim has been prescribed ch

Digiron [165]

Answer and Explanation:

My first response would be that it is not a good strategy to speculate things negatively in the very begining even when you have not tried it. We can definitely go for alternative drugs in case it doesn't fit to Jim's metabolic functioning and physiology. However, it is also possible that the drug would help Jim. Everybody is different when it comes to side effects of a particular drug. Some people even don't show any side effects for one particular drug whereas others show mild or significant concerns. Therefore, I would suggest her to reconsider her decision and try chlorpromazine as prescribed. After all, it is Schizophrenia and you cannot simply ignore it. Such negligence could worsen the situation for Jim and you all.

1. Which of the following are factors that both unicellular and multicellular organisms actively balance in order to achieve hom

MrMuchimi

The correct options are as follows:
1. C
Homeostasis is the process by which living organisms maintains constant internal environment. Maintaining homeostasis is very important because the survival of the living organism depend on it. In order to maintain homeostasis, the amount of wastes, nutrients and water that is in an organism must be controlled and maintained at optimum level.
2. A.
An organism that can not maintain an homeostasis will die. This is because, lack of homeostasis will disrupt the biochemical reactions which sustains the life activities of the organism and once the biochemical reactions that produce life energy can no longer take place the organism will die.
3. A.
For both unicellular and multi cellular organisms, when they are exposed to water containing no salt, much of the water will move into their cells. This happened because, the level of salt in the interior of the living cells is higher and so the water will move from the medium which has no salt to the inside to the cell where there is salt. This process is known as osmosis. In osmosis water move through a semi permeable membrane from the region of low salt concentration level to the region of higher salt level concentration.
4. D.
Cells in living organisms are able to maintain homeostasis by specializing in specific functions and by working together in cooperatively. Each cell has its own functions which it performs; in the process of its duty, it communicates with other cells which also help it in order to achieve common goals, which is maintenance of homeostasis within the cell.
