If the sequence of one strand on DNA is CTA GCT CCA, what is the<br> complementary strand? *
vekshin1

Answer:

If the sequence of one strand on DNA is CTA GCT CCA,  the complementary strand is GAT CGA GGT.

Explanation:

The DNA molecule has four nitrogenous bases in its structure, two purines —adenine and guanine— and two pyrimidines, cytosine and thymine.

The two DNA strands are linked by hydrogen bonds established between their complementary nitrogenous bases, where a purine is complemented by a pyrimidine.

In the case of DNA, adenine is complemented by thymine and cytosine is complemented by guanine:

<em>A=T</em>

<em>C≡G</em>

In the sequence belonging to a DNA strand CTA GCT CCA, the strand that is complementary would be GAT CGA GGT.

What’s the difference between a positive and a negative feedback loop. Give an example
3241004551 [841]

Answer:

Positive feedback loops enhance or amplify changes; this tends to move a system away from its equilibrium state and make it more unstable. Negative feedbacks tend to dampen or buffer changes; this tends to hold a system to some equilibrium state making it more stable.

Some examples of positive feedback are contractions in child birth and the ripening of fruit; negative feedback examples include the regulation of blood glucose levels and osmoregulation.

If a substance accumulates in an animal rather than being broken down, then at each trophic level the concentration of that pest
Romashka [77]

The process should be called biomagnification.


Biomagnification occurs because if one animal has some toxic substances in its body like pesticide, a larger animal that that has a higher trophic level than the smaller one will consume the smaller animal, and that the toxic substance is consumed too. However, the larger animal does not only consume one smaller animal, but a lot more. Therefore, if all the smaller animals have the toxic substance, the level of the toxic substance magnifies in the larger animal.


This cycle continues by a even larger animal eats more of the large animal and so the toxic level is even further magnified for the even larger animal. This goes on and on until the toxic level has reached a level that can kill the animal.


Biomagnification is often mixed up with bioaccumulation. Bioaccumulation happens in one organism, instead of the whole food chain. Bioaccumulation is where the toxic substance accumulates in only the organism. Since the substance cannot be excreted away. But bioaccumulation does not involve the higher trophic levels.


Therefore, your answer should be biomagnification.
