True. 100% true. Pollution is bad, and living things - even humans - can be effected in it in a negative way, so it's true
Part A:
<span>If early conditions of primeval earth had ammonia, methane, hydrogen in its atmosphere, then it is possible that amino acids such as glycine, α-alanine, and β-alanine may have been spontaneously formed from chemical reactions spurred by energy from lightning.</span>
<span>Their hypothesis was that the early conditions of primeval earth favored the spontaneous formation of organic molecules, from inorganic precursors, that may have been the origin of life. This theory is called abiogenesis. </span>
Part B:
<span>Miller Urey put methane, ammonia, hydrogen gases in a glass flask and a pool of water at the bottom of the glass flask. The flask was heated moderately to simulate the hot conditions then. Sparks were also occasionally induced in the flask to mimic lighting. The flask was then cooled slowly to simulate cooling of earth over time.After one day, they found the presence of some amino acids (glycine, α-alanine and β-alanine) was discovered in the water in the flask</span>

Not 100% positive on my answers but hope this helps!
Answer:
When organisms undertake sexual reproduction, new recombination of characteristics also appear in the progeny. Sometimes an organism may develop mutation in germ cells. In such cases, new characteristic may appear in progeny due to the mutation it has inherited
