Answer: c. Air pollution

Explanation:

There was a heatwave in Europe during the early years of the 21st century that killed tens of thousands across the continent and thousands in France.

Air pollution was blamed for having made the situation worse because the pollutants in the air acted to prevent heat from escaping back into the atmosphere which led to increased heat on ground and therefore a heat wave.

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.
