Biology

Deffense [45]4 years ago

Answer:

The correct answer would be "due to the absence of the sun".

During the night, solar energy is not available due to which light reaction or photolysis of water could not take place at efficient rates.

photolysis of water results in the production of oxygen, protons, and free electrons.

Thus, due to the absence of sun or solar energy during the night results in the decreased production of oxygen.

7. Why is approximately 50% of any individual's DNA inherited from that individual's father?
Strike441 [17]

Answer:

B. It was passed to the individual by a gamete from the father.

Explanation:

<u>DNA is transferred</u> to the next generation <u>via gametes</u>, which are produced during <u>meiosis</u>. During meiosis, <u>half of the genetic material</u> is <u>transferred</u> from parent cell to their gametes. Therefore, among the given options, only <u>B is correct</u>.

Option A is not correct because it talks about <u>somatic cells;</u> whereas, in somatic cells, <u>genetic material is not transferred half</u> rather duplicate first and then a complete duplicated set of genetic material is transferred.

Option C is also not correct because only <u>one gamete (sperm)</u> fertilizes the egg. Hence, not half of his cells descend from father gamete. Similarly, option D is also incorrect because it is not possible to descend half of the nuclei from the father to the offspring.
