Answer:
d) It binds to intracellular receptor.
Explanation:
Nitric oxide is a compound produced by many cells of the body. It relaxes vascular smooth muscle by binding to the heme moiety of cytosolic guanylate cyclase(intracellular receptor) ,activating guanylate cyclase and increasing intracellular levels of cyclic-guanosine 3',5'-monophosphate, which then leads to vasodilation.
Cycad is more closely related to the Arabidopsis . It is so as the closest species from the node of cladogram posses the most common traits as each node represents the end of the ancestral taxon and the species that further split from the node are called sister taxa.
