dmitriy555 [2]

During the postnatal stage, the various major systems in the body develop at different rates, with the brain reaching full development first, then dentition, then the whole body, and finally the reproductive system. Thus, option "C" is correct.

<h3>What is postnatal stage?</h3>

The postnatal stage-from infancy to childhood to the juvenile period to adolescence to adulthood-involves growth acceleration and deceleration. Childhood and adolescence are long events, in which adult behaviors are learned, individuals become completely mature, and the reproductive capacity develops.

Thus, option "C" is correct.

Some photosynthetic bacteria contain the protein bacteriorhodopsin, which absorbs light and pumps protons out of the cell direct

Yanka [14]

Answer:

Explanation:

Bacteriorhodopsin is one of the simplest protein from a family of a protein called opsin which is present in photosynthetic bacteria, algae and few fungi.

The bacterio-rhodopsin acts as an active light-gated proton pump which can pump the protons against their concentration gradient and then establishes concentration gradient across the membrane.

When the photosynthetic bacteria gets exposed to the light, bacteriorhodopsin pumps the proton from the cytosolic side to outside. This establishes electric motive force across the membrane which causes disequilibrium of protons.

The protons move back from the outside of the membrane to inside through H+ATPase which help allow the generation of ATP in the cell.

It has been demonstrated that environmental uva and uvb levels have resulted in this feature in homo sapiens:

Sedaia [141]

Answer:

variation in skin color.

Explanation:

The human skin color is determined genetically depending on the amount of melanin. However pigmentation can occur as a results of exposure to uv rays that causes induced pigmentation.

The sun emits two types of ultra violet rays which can reach can reach the skin namely the uva and uvb. Both type of rays can damage the skin if unprotected. Due to this there was evolution against the damaging rays. More melanin that provides a natural sunscreen to the people leaving in the tropic environment.

Melanie is asked to list the complementary base pairings of a DNA sample in her lab. What is the MOST appropriate response she c

rodikova [14]

Answer:

AT, CG, CG, AT, CG

Explanation:

Hi, the answer is the last one, AT, CG, CG, AT, CG.

When we read the question, it says base pairings of a DNA sample in her lab. The only base pairs in DNA is A, T, C, and G.

A is complementary to T, and C is complementary to G.

Therefore, you can eliminate the first three.

Hope this helps you!
