All enzymes have an optimum ph. in short, some enzymes can only function within a
narrow range of ph values; in contrast, a few enzymes can function in a broad range of
ph values. see the graph of pepsin and arginase in the follow-up questions. thus, an
enzyme that has specific ph requirements will have a
slope
(describe the slope). in contrast, an enzyme that can function in a range of ph values
will have a
_slope (describe the slope).

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.

answer; the tunica intima also called tunica interna, consists of elastic fibers,connective tissue and smooth muscle cells;
