Answer:
c Aquaculture produces large amounts of seafood for human
purchase and consumption year-round.
Explanation:
Most seafood produced via aquaculture is destined for human consumption, which has added to the sector’s momentum. The ability to dependably harvest many different species of finfish, shellfish and aquatic plants has also facilitated gains for the world’s aquaculture industry.
A because it uses a FAN-BOY
The answer is LH only.
Luteinising hormone promotes the release of an egg
from an ovary during ovulation. Follicle Stimulating Hormone, on the other hand, stimulates
the maturation of ovarian follicles. When its levels
drop and LH surge, ovulation of a mature
egg from the mature follicle occurs.
Answer:
The answer is D
Number of motor units recruited
Explanation:
The force a muscle generates is dependent on the length of the muscle and its velocity which is shortened.
A motor unit is the grouping of muscle fibers supplying nerves by the neuron and consists of the motor neuron.
The number of muscle fibers within a motor unit varies, and is a function of the muscle’s ability for accurate and refined motion.
Precision can be determined to be inversely proportional to the size of the motor unit. As a result, small motor units can exercise greater precision of movement compared to larger motor units. For example, thigh muscles which are responsible for large powerful movements, can have a thousand fibers in each unit, while eye muscles which requires small precise movements, might only have about ten.
Groups of motor units are supplied with nerves to coordinate contraction of a whole muscle and generate appropriate movement; all of the motor units within a muscle are referred to as a motor pool.
As a result, the number of motor units with are recruited will facilitate the maximum amount of tension that allows the student keep his arm extended in place under the increasing weight of the books.
