Describe three traits that might be desired in sheep. how can these traits be passed on to the next generation? explain.

1 answer:

7 0

Sheeps possibly should be able to run quickly, to have a good sense of smell and to have quick reflexes.

These three sheeps are desirable for sheep as they enhance their survival capabilities. These traits are passed on to the new generation through reproduction.

Now can you predict nucleotide quantities in a hypothetical scenario with more than four different types of nucleotides? An alie

Answer:

16% is G

12% is T

12%is A

22% is X

Explanation:

Given that each nucleotide is complimentary to another nucleotide, there cannot be more of one than the other. For example, C bonds to G, so there cannot be more C than G, because there would be nothing for it to bond to.

So if there is approximately 16% of the genome composed of C, that would mean that approximately 16% is composed of G (for it to bond to).

The same logic can be used to determine the amount of nucleotide X is present. If Y binds to X, and approximately 22% is composed of nucleotide Y, then the same percentage can be given to nucleotide X, and say the amount of X is 22%.

Now all of the nucleotides have to add up to 100%, so:

A + T + G + C + X + Y = 100%

A + T + (16%) + (16%) + (22%) + (22%) = 100%

A + T = 24%

Given that A binds to T, they must be equal to each other, hence we can say that the concentration of A, equals the concentration of T.

Therefore, the concentration of A is 12%, and the concentration of T is also 12%.

Which observation provides evidence that a cell is most like/ya prokaryote?

Over [174]

Answer:

C. It has DNA that is not contained within a nucleus.

Explanation:

If we look at golgi apparatus, they are one of the most prominent characteristic of a eukaryotic cell because they are membrane bounded organelles. As we know that in prokaryotic cells there are no membrane bounded organelles so option A is incorrect.

If we talk about long tail like structure, then it can be correct option because many prokaryotic organisms like bacteria have flagella for movement. However, there is Euglena which has flagella but it is a eukaryote. It means that option B can be false.

If we look at option C, it says that DNA of the cell should not be necessarily in nucleus. This looks suited for prokaryotes like bacteria because they donot have any nucleus and DNA is positioned almost center of the cell without any nucleus. So option C is best option.

If we look at option D, again it cannot be right answer because they are one of the most prominent characteristic of a eukaryotic cell that their organelles are large and covered with membranes.

Hope it helps!

differences between the structure of the wall of the stomach and the structure of the wall of the ileum

JulijaS [17]

Answer:

Wall of stomach : it has three layers of muscle instead of two. Under these muscle layers is the adventitia, layers of connective tissue continuous with the omenta. The epithelium of the stomach forms deep pits, called fundic or oxyntic glands.

wall of ileum : The wall itself is made up of folds, each of which has many tiny finger-like projections known as villi on its surface. The ileum has an extremely large surface area both for the adsorption of enzyme molecules and for the absorption of products of digestion.

Three characteristics of enzymes

choli [55]

1)Enzyme is a protein. The main material of an enzyme is protein
2)It is easily influenced, by environmental change. Environmental factors include temperature, pH, and inhibitor.
3)It acts as catalyst The enzyme functions in accelerating chemical reaction, but the enzyme itself does not change after the reaction ends.
