3. What is the difference between cotyledons in dicot seeds and the endosperm in monocot seeds?
cupoosta [38]

Explanation:

Monocots contain a single cotyledon in their seed and dicots contain two cotyledons. The nutrients in the endosperm of dicots is absorbed by the two cotyledons. Therefore, a tiny endosperm is found inside the dicot seed. However, the main difference between cotyledon and endosperm is in their function during seedling.

Which of the following characteristics are true for an action potential?
pickupchik [31]

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.
