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.
Question: The ___________ in males and the _________ in females are permanently blocked when an individual undergoes a sterilization procedure.
Answer: vas deferens in males; fallopian tube in females
The vas deferens (males) and fallopian tube (females) underwent permanent blockage when the individual is undergoing the procedure of sterilization.
Answer:
125
Explanation:
The correct option would be 125.
<em>The carrying capacity of a particular environment generally refers to the maximum number of individuals of a particular species that the environment can support at a particular time based on the resources it has. Hence, the maximum population of a species will normally oscillate around the carrying capacity of the environment where it is found. </em>
In the case of the elephants in the illustration, the maximum population recorded was 125. The population decreased from this value at some point only to increased back to it later.
<u>Hence, the carrying capacity for the elephant is 125.</u>
