cannot breathe, is not a living organism, doesn't grow doesn't move
Answer:
negative feedback
Explanation:
Insulin reduces blood sugars when the levels are high in the blood. The hormone is produced by the pancreas and binds on receptors of cells. This initiates cell signaling mechanisms that signal the cell absorb sugars. When the blood sugars get back to normal, insulin production is reduced.
Answer:
The mutations lie at locations where they don't affect protein sequence due to degeneracy of the genetic code.
Explanation:
Genetic code is the set of the triplet codons each of which code for a specific amino acid. The nucleotide sequence of mRNA is read in the form of triplets during the process of protein synthesis and the respective amino acid is added to the growing polypeptide chain. The genetic code is degenerate. This means that more than one triplet code specifies one amino acid and some amino acids are encoded by more than one codon.
For instance, genetic codes CUU, CUC, CUA, CUG specify amino acid "leucine". Therefore, any change in the DNA sequence that replaces one code for the leucine with another would not affect the amino acid composition of the protein. This would result in the synthesis of proteins with the same amino acid sequence from both the wild type and mutated genes.
The zygote undergoes mitosis where it divides and doubles it's cells. This is called the germinal phase.
Answer:
The correct answer is - A. Producing offspring that are genetically identical to the parents
Explanation:
Genetic variation is the difference between the population or individual on a genetic level. If there is a change in the DNA of individuals or among the population, it is genetic variation in these organisms.
There are several factors that result in genetic variation such as random mating, random fertilization, mutation, crossing over during meiosis, and many more. Producing genetically identical offspring to the parents is not a factor as there is no variation is taken place on the genetic level.
