Answer:
The correct answer is - option A.
Explanation:
Elephant populations are currently declining lapidary. Human influence is the main and major reason that leads to such a population decline of the elephants. The habitat loss, environmental change, and killing for human safety are the few reasons that affect the population of the elephant, but the major and most responsible cause of the killing and decrease in the elephant population is killing for the ivory of elephants,
Elephant ivory is very expensive and use for making jewelry, artifacts and many more items even illegal medicines are made by ivory.
Thus, the correct answer is option - A.
Answer:
inactive proteins can be activated by phosphorylation
Explanation:
Proteins are regulated after translation by the non-covalent binding of small molecules. These molecules include amino acids or nucleotides. A change in the conformation and thus, the activity of the protein is usually achieved when this occurs.
Proteins could also be regulated by phosphorylation which is the addition of phosphate groups of specific amino acids on the protein.
Answer: 3- mutation, natural selection, migration
Explanation:
1-genetic drift, mutation, natural selection
2-mutation, founder principle, bottleneck effect
3-mutation, natural selection, migration (gene flow)
The correct answer for this question is" #3.mutation, natural selection, migration (gene flow)." The sequence of evolutionary mechanisms which have come into effect in each event is that of mutation, natural selection and migration. There is a steady rise in the population of bright-colored fish. Both populations thrive.
