Answer:

The correct answer is option d, that is, it prevents the enzyme, which degrades cyclic GMP.

Explanation:

Oral therapy for erectile dysfunction is Viagra, which is the citrate salt of sildenafil, it works by preventing a specific phosphodiesterase type 5 or PDE5, which is the inhibitor of cGMP. During sexual stimulation, nitrous oxide is released in the corpus cavernosum causing the erection of the penis in males. The nitrous oxide then stimulates the enzyme guanylate cyclase that further makes the concentration of cGMP to elevate, this generates smooth muscle relaxation in the corpus cavernosum and permitting blood the inward flow of blood.

Viagra works by increasing the influence of nitric acid by preventing PDE5, which is accountable for the deprivation of cGMP in the corpus cavernosum. At the time of sexual stimulation, the discharging of nitrous oxide takes place, the viagra inhibits PDE5 causing the levels of cGMP to elevate in the corpus cavernosum leading to smooth muscle relaxation and continuous flow of blood to the corpus cavernosum.

The phylum Cycliophora are tiny organisms that live in large numbers on the outsides of the mouthparts and appendages of lobster
Tom [10]

Answer:

The answer to the question above is option B (Eumetazoa and Lophotrochozoa)

Explanation:

Cycliophorans exhibit sexual dimorphism, they live on the mouthparts of their lobster hosts using anterior buccal funnel; oval-shaped trunk; and posterior, acellular stalk, with an adhesive disc which they use to attach themselves to their hosts’ mouthparts. Cycliophorans do not feed during free swimming stages and are filter feeders during their sessile stage.

Cycliophorans live on lobsters, they do not generally adversely affect their hosts, although it is possible for large numbers of cycliophorans to clog their host's mouthparts.

Coelom is the fluid-filled cavity within the body of most multicellular animals, except some invertebrates, it acts as a cushion for the internal organs of the organism. Animals which have a space between their digestive tract and body wall and entirely lined by mesoderm are termed as coelomate animals.

Eumetazoans include radially-symmetrical animals and bilaterally-symmetrical animals that have true tissues organized into germ layers, and an embryo that goes through a gastrula stage, and are distinguished by their characteristic epithelia,

The characteristic features of the group lophotrochozoa are, they are animals with  ciliated larval phase, and they have the presence of a trochophore larvae and a feeding structure called lophophore.
