The choice that best describes when a cell becomes 2n is : ( C ) after meiosis when froming a zygote

Mitosis is a single round division of a parent body cell which produces two ( 2 ) identical diploid daughter cells ( 2n cells ). while Meiosis is the divison of parent gametes which produces four ( 4 ) haploid daughter cells. Meiosis leads to the production of gametes.

Hence we can conclude that The choice that best describes when a cell becomes 2n is : after meiosis when froming a zygote

All the possible gametes for Aabb would be Ab and ab; that of AABb would be Ab and AB; that of AaBB would be AB and aB; that of AAbb would be Ab; that of AaBb would be AB, Ab, aB, and ab; and that of aabb would be ab respectively.

The formation of gametes for a dihybrid involves the crossing of the two traits involved.

Thus: Aabb is equivalent to crossing Aa and bb

                           Aa   x   bb

                       Ab   Ab   ab   ab

Hence, all the gametes would be Ab or ab.

For AABb:                     AA   x   Bb  =   AB   Ab   AB   Ab

The gametes are either AB or Ab

For AaBB: the gametes are either AB or aB

For AAbb, only Ab gametes are produced

For AaBb: the gametes would be AB  Ab   aB and ab

For aabb: only ab gametes are produced.

An error is to describe arteries as the vessels that always transport oxygenated blood instead of describing them as vessels that take blood away from the heart.

An artery is a big blood vessel that transport enriched oxygen blood to all part of the human body.

This rich oxygen blood is used by human tissues to carry out cellular respiration (aerobic cell respiration).

Moreover, veins are other types of blood vessels that are also capable of carrying blood toward the heart.

The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species.

Explanation:

Original Question:

Describe the theory of evolution in your own words. How does this theory relate to the principle of natural selection?

Answer and Explanation:

Evolution means the adaption of animals, plants, species, etc. This study ties in with the theory of humans being descended from other animals; specifically chimpanzees. Over the course of time, Animals are believed to adapt to the environment they live in. One common example would be giraffes. In the past, they used to have shorter necks that couldn’t the leaves in a tree. Throughout the years, many breeds tended to have offsprings that had long necks. That is why giraffes have longer necks now.

Explanation:

The neuron is a highly specialized type of nervous system cell that is called unipolar when dendritic and axonal processes are continuous and the soma lies off to one side.

The neuron is the structural and functional unit of the nervous system, which when they have only a short projection that later branches into two or more branches, are considered unipolar.

That is, they are those neurons in which only one extension or neurite emerges from the soma, which will act as an axon and at the same time will have dendrites with which it can both receive and transmit information.

Therefore, we can conclude that the neuron is a highly specialized type of nervous system cell that is called unipolar when dendritic and axonal processes are continuous and the soma lies off to one side.
