Answer:
When it comes to crickets, fitness means one's reproduction in producing as many offspring as possible, so the chances of their offspring living are higher. In addition, the passing on their genes is the most important for their offspring's evolution.
Answer:
The correct answer is translation.
Translation is the process by which amino acid polypeptide chain is synthesized based on the sequence provided by mRNA.
Ribosomes are considered as the sites of protein synthesis.
mRNA is placed between the small and large sub-units of the ribosomes.
Specific tRNA decodes the codon present in mRNA with help of anti-codon present in int.
Based on this codon-anti-codon interactions, specific tRNA adds specific amino acid to the growing polyeptide chain in the ribosome (in one at a time manner).
Many tRNA(s) are required to build a single polypeptide chain which eventually transforms into a functional protein after several modifications.
Hence, if tRNA is inhibited from delivering amino acids to the ribosome the process of translation would be inhibited.
Answer: It is possible for two O bloody type to have a child of Blood type B which can be caused by mutation.
Mutation is the changes in genetic content or DNA . Although it is normal for two O blood type parents to have O type child but it is technically possible for O blood type parents to have child of A or B blood type which is due to changes in DNA. Changes in DNA can be caused when sunlight hit our bodies, conversion of food to energy , when our body absorb some chemicals and when our cells try to copy another DNA. The differences between the blood types A, B, and O is very small. This makes it possible for a mother of O blood type produce B egg or a father of O blood type produce B sperm which is caused by mutation.
For a parents with blood type O to have a child with B type blood, the parents blood type O would have to look like B type .
Explanation:
Mutation is the change in genetic material or DNA. It can lead to change in blood type of humans with different parents blood types. This mutation can be caused by chemicals we breathe in, exposure to sunlight and so on.
