Answer:
True.
Explanation:
It is TRUE that Polyculture is well suited to intensive aquaculture because you have two or more non-competing species in the same system.
This is evident in the fact that Polyculture is a type of agriculture whereby more than one species of plant is cultivated or animals reared simultaneously.
For example, Polyculture in animals may involved paddlefish, tilapia, and bighead carp reared in the same pond. In this case, the paddlefish will feed on crustaceans, while tilapia feed on zooplankton and phytoplankton. Also, bighead carp will feed on zooplankton and big phytoplankton.
Answer: a. action potential frequency is high enough that no relaxation of muscle fibers occurs.
Explanation:
A tetanic contraction occurs due to repeated stimuli at short intervals. In this situation, the muscle fiber does nor relax and contracts again. It is a process of sustained contraction of muscles, which evoke when the motor nerve innervates a skeletal muscle and emits the action potential at high rate. The muscles become hyperactive in this condition.
