Answer:
amino acid is the monomer that makes up the polymer known as the protein.Hence,amino acid is the monomer of protein.
Answer:
The correct answer will be option D.
Explanation:
DNA replication is a complex process which forms the exact copy of the DNA molecule from the existing DNA. This process takes place during the synthesis phase or S-phase of the cell cycle which takes place in the cytosol of prokaryotes and nucleus of the eukaryotes.
The most common way of producing replicas of the DNA molecule is through semi-conservative mode in which each strand of DNA is synthesized from both the strands of the parental DNA using as a template.
Thus, option D is the correct answer.
<span>The correct answer is cGMP.</span>
<span>cGMP, during the dark (when there are no stimulations of photoreceptor cells), reaches high intracellular levels. When the light stimulation occurs cGMP levels decrease because it is converted to GMP by phosphodiesterase. Phosphodiesterase is activated by transducin which is activated by excited rhodopsin (contains photopigment).</span>
<span>
Low levels of cGMP block the cGMP gated ion channels and that prevents the entry of Na and Ca. Because of that membranes becomes more negative, hyperpolarization occurs and this creates a signal for the next cell.</span>
