The correct answer is E)52

When there is Hardy-Weinberg equilibrium like in this case of a single locus with two alleles denoted A and a with frequencies f(A) = p and f(a) = q, the expected genotype frequencies under random mating are f(AA) = p² for the AA homozygotes, f(aa) = q² for the aa homozygotes, and f(Aa) = 2pq for the heterozygotes. Let's put that A is dominant and a is recessive allele. In Hardy-Weinberg equilibrium we have:

p²+2*p*q+q²= 1     p+q=1      p=1-q

f(a) =0.4=q            q²=0.4²=0.16=16%    

p= 1-0.4=0.6         p²=0.6²=0.36=36%

Percentage of a homozygous genotype in the population is 16%+36%=52%

Place the following events that occur at the vertebrate neuromuscular junction in the correct order. I Depolarization of the mus
meriva

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.
