es into the lungs. The human body can store many nutrients, but it can’t store oxygen. Oxygen is essential for all cells to function properly. That’s why humans have to breathe continually to stay alive. Respiration also moves carbon dioxide, a waste product, out of the body.
Which of these best describes the relationship between respiration and oxygen?

A
Oxygen is the process by which respiration happens.

B
Respiration and oxygen are both types of gases.

Which phase of cell division is shown?
GarryVolchara [31]

The image shows the phase of cell division  called telophase II.

<h3>What is Telophase II?</h3>

It is the last phase of mitosis, the sister chromatids separate, the chromosomes decondense, the achromatic spindle breaks down and the karyotheca, and consequently the nucleoli, reappear. With cytokinesis, in telophase I two daughter cells are formed and continue in the process of division until telophase II.

In this case, we can see in the image that the chromosomes decondense so we have telophase II.

Individuals in a population of purple people earters are polymorphic at a single locus that leads to variation in purple people
Allisa [31]

Answer:

The correct answer is - overdominance.

Explanation:

In the given question, genotype Pp is a heterozygote condition that has a 54% survival rate or fitness thus these individual people get more chance of mating and increase in number as compared to the other two conditions of PP or pp traits where PP has 45% survivability, less than heterozygous condition and more than pp that has only 4% rate.

It results in a normalizing selection model of natural selection as a moderate trait, that is heterozygote, is selected. Thus, the selection of overdominance which means heterozygote condition produces a better phenotype than PP or pp parents is heterosis.

"Replication forks from the same origin of replication extend __________. __________ DNA strand is used as template for the lead
cluponka [151]

Answer:

Explanation:

Replication forks from the same origin of replication extend from the beginning of the strand to the end where the enzyme helicase helps to move the replication fork unwinding DNA double helix structure by breaking the hydrogen bonds between the Nitrogenous bases.

DNA strand is used as template for the leading strand at one fork and for the lagging strand at the second fork. New DNA is synthesized from 5' to 3' on the leading strand.

The strand is made continuously forward in the direction of the replication fork while the other strand is made in 3' to 5' direction and been referred to as ozazaki fragments.
