Answer:
Nerve impulse
Explanation:
A nerve impulse is transmitted through the synaptic cleft by acetylcholine. When an impulse reaches the synaptic knob, it stimulates the vesicles to move towards the presynaptic membrane releasing the acetylcholine. The transmitter substance makes the membrane permeable. An action potential is then formed along the neuron.

Answer:
.45 from mom, .05 from dad
Explanation:
Given that:
the mother's genotype is AZ/az
i.e AZ = 50%
az = 50% (parental)
But we were also told that the recombination rate is 10% which will like wise affect the mother's genotype
So 100% -10% = 90 % of the mother's genotype
We have a new genotype
AZ = 45%
az = 45% (parental)
Therefore the probability of az gamete from the mother = 
= 0.45
Similarly; the genotype of the father is: Az/aZ
This is an heterozygous father who is diploid hence, there is a remarkable presence of two copies of each autosomal chromosome.
Az is the allele of the genes in one chromosomes and aZ is the allele of the genes in the other.
The gametes of this self cross are: Aa, AZ, az, zZ
Therefore; the recombinants are:
AZ
az
Since there are 10% recombinant; then
AZ = 5%
az = 5%
Therefore the probability of az gamete from the father = 
= .05
Answer:
The correct option is D.
Explanation:
Primates refer to an order of animals that include: apes, monkeys, bush babies, etc. The group is very diverse and include up to 350 different species. The smallest primate is mouse lemur while the biggest is wild gorilla. Generally, primate have pairs of prehensile hands and feet, flexible shoulders and hips and well developed brains. They also have hands that are sensitive to touch. Primates have different foraging methods, which they use to acquire their foods.
