Answer:
Option C
Explanation:
In elephant seals, the male arrive the beach first and start establishing its territory. Once their territory is established female elephant seals starts arriving at the beach and prefer mating with the male who can defend their territory or females in his territory from other males. All females in the territory of specific male mate with the male give birth to their pups and after staying for few months move back into the water.
hence, option C is correct
A biological community of interacting organisms and their physical environment.
1. Action potential reaches the axon terminal and depolarizes it.
2. Depolarization opens voltage-gated calcium channels, enabling influx of Ca into the neuron.
3. Calcium binds to specialized proteins on vesicles (containing pre-made acetylcholine) and triggers them to fuse with the neuron membrane at the synapse.
4. Exocytosis of acetylcholine into the synaptic cleft occurs.
5. Acetylcholine diffuses across the synapse and binds to nicotinic receptors on the end plate of the myocyte.
6. Activated nicotinic receptors, themselves ion channels, cause cation influx into the myocyte and generate an end plate potential. This eventually gives rise to the full depolarization within the myocyte that enables contraction.
