Answer:
The correct answer is option D) selective breeding.
Explanation:
Selective breeding is a process in which human selects a particular organisms for breeding purpose to avail a specific characteristics in the offspring which is present in the organisms that are used for breeding. For example, if a person wants a cow that produces high amount of milk so it can breed the local cow with male of high milk producing specie. So the calf which is formed have the characteristics of high milk producing specie.
Answer:
Relative dating is the science of determining the relative order of past events.
Explanation:
Relative age dating determines whether one geological or paleontological event happened before or after a second event.
Since all cells in our body contain DNA, there are lots of places for mutations to occur; however, some mutations cannot be passed on to offspring and do not matter for evolution. Somatic mutations<span> occur in non-reproductive cells and won't be passed onto offspring. For example, the golden color on half of this Red Delicious apple was caused by a somatic mutation. Its seeds will not carry the mutation.

A single germ line mutation can have a range of effects:
<span><span>No change occurs in phenotype.
Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.</span><span>Small change occurs in phenotype.
A single mutation caused this cat's ears to curl backwards slightly.</span><span>Big change occurs in phenotype.
Some really important phenotypic changes, like DDT resistance in insects are sometimes caused by single mutations. A single mutation can also have strong negative effects for the organism. Mutations that cause the death of an organism are called lethals — and it doesn't get more negative than that.</span></span>
Answer: A) genes involved in the cell cycle.
B)<span>There is a change in shape of the receptor which triggers the stopping of the signaling cascade</span>
