Answer:
I, II, III
Explanation:
A threshold stimulus is a stimulus that is capable to produce a response in excitable tissues such as neurons and muscle fibers. At threshold potential, the outward movement of K+ and inward movement of Na+ become equal to each other. When the potential exceeds the threshold potential, more and more Na+ enter the cell to depolarize it and to allow the opening of Na+ channels. Therefore, to fire an action potential, the threshold must be exceeded.
Conduction of action potential is all or none phenomenon which means that either it occurs or it does not occur. As an impulse is passed by each successive part of an exon, it enters the refractory period during which there is no conduction of nerve impulse. It ensures the one-way conduction of impulse from the cell body to the axon terminal only.
Meiosis sexual reproduction only occurs in the gametes, which do not contribute to the body's growth and repair, only reproduction.
Replication mitosis, however, produces diploid cells identical to the parent/mother cell, which aids in the body's growth and repair.
Renewable resources are easily obtained and can be created quickly. Things like fossil fuels take millions of years to create. C is the answer because as k stated fossil fuels are nonrenewable and take millions of years to create, Soybeans are easily made so it's renewable.
Hope I helped. :)
