Answer:
a. inhibits cAMP phosphodiesterase, the enzyme that converts cAMP to AMP.
Explanation:
The phosphodiesterases are a group of enzymes that are capable of breaking phosphodiester bonds such as those between nucleotides in nucleic acids. The Cyclic adenosine monophosphate (cAMP) is a second messenger involved in intracellular signaling pathways. This molecule (cAMP) is hydrolyzed by the cAMP-dependent phosphodiesterase, which catalyzes the enzymatic breakdown of phosphodiester bonds (i.e., hydrolyzing cAMP to 5-AMP). The cAMP levels are modulated by the balance between its generation and the degradation via cyclic nucleotide phosphodiesterase.
The answer would be D. Tropical Rainforest, this would be due to the abundance of rain which creates plenty of vegetation and then, more herbivores will live in the rainforest, and the more herbivores there are, the more carnivores will come to the rainforest. The canopy of the tall trees also provide shelter for countless of thousands of species of birds.
The answer is <span>C. reductions of chromosome number.
Meiosis is also known as a reduction division of the cells. The reason for that is because during meiosis the diploid cells are divided into haploid cells. Meiosis consists of two divisions - meiosis I and meiosis II. In meiosis I, the number of chromosomes is reduced, while meiosis II is similar to mitosis. In both meiosis and mitosis, however, cell division, duplication of chromosomes, and production of new cells are common processes.</span>
