Answer:
Generation of an action potential in the neuron.
Stimulation of Ca2+ entry into the neuron
Release of acetylcholine into the synapse
Depolarization of the muscle fiber membrane
Explanation:
The following events takes place in the vertebrate neuromuscular junction
a) Nerve Action Potential - Action potential reaches the axon terminal
b) Entry of calcium ion - The calcium ion reaches the axon terminal and enter into the presynaptic terminus after which the Synaptic vesicles fuse with the membrane of axon terminal
c) Releasing of Arch Quanta - Acetylcholine is released into synaptic cleft which then binds to the receptor sites on motor end plate
d) The Na+/K+ channels opens and Motor end plate becomes depolarized.

Galapagos species are among those populations whose
members do not interbreed. The reasons that keep them from mating is that they
are separated due to differences in songs and beaks, individuals only recognize
and respond to songs of their own species. Therefore, geographic isolation and different
environments led to changes in traits that affected mating.

Answer:
lower than
Explanation:
The protons obtained from the spit of hydrogen atoms, to protons and electrons, (which was transported to the Matrix of the mitochondria by NADH and FADH2 ) are pumped by PMF into the intramembrane space.
The constant pumps by the PMF,due to the electron transport chains set up high concentration of Hydrogen ions in the intramembrane space.If pH is -log[H+] then the high the number of H+/protons,the stronger the acidity,and lower the pH of the medium.
This set up higher electrochemical gradient compare to the matrix.Thus H+ diffuses down the gradients into the matrix.
This generate energy needed for the synthesis of ATPs by ATPase synthase in the matrix
I'm assuming there is a graph to go along with the question but as a guess, The numbers of lynx and rabbits flow as opposites when rabbit population goes up soon after the lynx population wil also go up due to increase in food, then the rabbit population will go down due to the increase in predators. This patern will continue on.
