In fish, what is the advantage of countercurrent exchange in the gills?.

It removes a high percentage of oxygen from water. (More than 80% of oxygen is removed from the water as a result of countercurrent exchange.)

explanation:

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.
