Evolution is one of the unifying themes of biology. Evolution involves change in the frequencies of alleles in a population. For

a particular genetic locus in a population, the frequency of the recessive allele (a) is 0.4 and the frequency of the dominant allele (A) is 0.6.
Identify a particular environmental change and describe how it might alter allelic frequencies in this population. Explain which condition of the Hardy-Weinberg principle would not be met.

A Mutation occurring in the population will change the allelic ratio.

<h3>What is evolution?</h3>

Evolution refers to the changes that occurs in organisms over a long period of time such that those changes results in new species better adapted to their environment and having higher specialization.

One of the factors of evolution is mutation.

According to the Hardy-Weinberg principle, the allele and genotype frequencies of a population of organism in equilibrium will remain constant in the absence of evolutionary influences.

Therefore, if a mutation occurs in the population, the allelic ratio will change.

gogolik [260]

Answer:A,B,D,E,F

Explanation:

Stock can be transfer depending on the organization.

The movement of stock is divide into three broad categories

Stock transfer from Plant to plant- movement of stock from a plant to another plant

Stock transfer from Company code to company code- movement from ome company code to another

Stock transfer from Storage location to storage location

Between different plants within the same storage - stock can be moved from one plant to another within the same storage this will lead to a change in quantity in both plant and it should be noted

Between storage locations within one plant- stock location can be change in a plant but it doesn't affect the quantity.

Between plants in different company code- stock can also be moved from one company code to another this requires adequate documentation when the stocked are moved.

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.
