Answer:
Explanation:
This is because once a Voltage Gated Sodium Channels closes up after depolarization, they can not be reopened.The transmission of action potential is such a way that they are propagated one after the other in a forward direction, and never backwards. Thus once a sodium channel depolarizes,it closes up, to under go a shot rest.No matter the strength of the next stimulus it will not open. Then the channel ahead of it opens to depolarise to conduct action potential, this again after shut opening closes up for the channel ahead to open. This short period of rest when the sodium channels closes up is called refractive period. However after sometime of rest the rested sodium channels open, from the inactivated stage to conduct action potential.

A hypothesis is an educated guess while using reasonable thinking, about the answer to a scientific question. Although it is not proof in an experiment, it is the predicted outcome of the experimentation. It can either be supported or not supported at all, but it depends on the data gathered.
The rose family is a medium-sized family of flowering plants. The rose family (Rosaceae) is one of the major angiosperm families. The leaves are generally arranged spirally. Flowers of plants in the rose family are generally described as "showy". They are actinomorphic and almost always hermaphroditic. Rosaceae generally have five sepals, and five petals. They also have many spirally arranged stamens. The bases of the sepals, petals, and stamens are fused together to form a cup-like structure called a hypanthium. They can be arranged in racemes, spikes, or heads; solitary flowers are rare.
