When DNA replication occurs, the DNA strand is being unwound, causing the DNA to be overwound tightly past the replication fork.
For example, If you have ever wrapped two strings around each other and then tried to pull part the middle of the string while holding the ends tight, the rest of the string past the place you're pulling the string apart becomes very tight and strained.

Topoisomerase is an enzyme that binds to the DNA and helps release some of that strain by unwinding the DNA past the replication fork.

That means the correct box is the leftmost one. Hope this helps:)

Basically the question is asking you, out of these statements:

A) Meiosis results in four haploid daughter cells

B) Meiosis results in four diploid daughter cells

C) In both processes, DNA replication must occur

D) During meiosis the 2N mother cells produces N daughter cells

E) Mitosis is responsible for genetic continuity, in higher organisms it is essential for growth and repair

which one(s) are true. They provide you information (Venn diagram as well as paragraph) to help you solve this question.

The information tells us what's the correct answers.

Say for an example, the venn diagram tells us that unlike mitosis, during the process of meiosis the 2N mother cells produces N daughter cells (hence why you see the equation 2N ---> N only in meiosis' circle instead of in the middle [which signifies that both mitosis and meiosis shares this trait] or on mitosis' side [which signifies that only mitosis has this trait].) Therefore, D - or the fourth - answer choice is correct, so identify it as a true statement.

A - or the first answer choice - is correct as well. B - or the second answer choice - is not so do not identify it as true. In the paragraph it tells us that instead of two identical daughter cells with the same chromosome number (which is a diploid cell) and DNA, four daughter cells are produced with half the chromosome number, which is a haploid (think of half when you see haploid).

C - or the third answer choice - is right. In the paragraph is states that both processes have DNA replication take place. For mitosis it states "The parent cell goes through DNA replication(...)". For meiosis it states "(...) DNA replication still takes place (...)".

E - or the last answer choice - is correct. In the venn disgram, it has growth and repair under mitosis and the paragraph states that for mitosis, simple organisms use this process as a method of asexual production (which, by the way, maintains genetic continuity).

So, here's our recap:

A is a true statement. Identity it as true.

B is NOT correct thus do <em><u>not </u></em>identify it as true.

C is a true statement. Identify it as true.

D is true thus identify it as such.

E is too true. So, identify it.

Ways to identify includes and is not limited to:

* circling

* highlighting

* selecting

* writing T or true by what's true

* underlining the true statements

* checking the true statements with a check mark

You can signify B as untrue by writing F or false by it, crossing it out, putting an x by it, or simply leaving it be. It all depends on what you're able to do.

Data clusters are sets of signs or symptoms that are grouped together logically. Match each sign or symptom with its appropriate
aivan3 [116]

Answer:

Explanation:

(A) PaO₂ below normal: PaO₂ is used to describe the partial pressure of oxygen dissolved in the blood. When it is below normal, it indicates the individual isn't getting enough oxygen hence there is low pressure of dissolved oxygen in the blood. This sign/symptom falls under the Respiratory/oxygenation data cluster.

(B) Dyspnea on exertion: Dyspnea is a term used to describe shortness of breath while dyspnea on exertion is when an individual runs out of breath as a result of not been able to breath deeply/properly during or after an exercise. This sign/symptom also falls under the Respiration/oxygenation data cluster.

(C) Productive cough: This is a type of cough that produces/forces mucus out of the airway (thereby clearing the airway). This sign/symptom from this description is also Respiratory/oxygenation data cluster.

(D) Oxygenation saturation 92%: Oxygen saturation is when the body can supply enough oxygen to the cells and tissues within it's system. This sign/symptom is also a Respiratory/oxygenation data cluster.

(E) Feels "too tired to do much": This can also be referred to as fatigue. This is usually as a result of inadequate energy produced (usually from glycolysis) in the body. This sign/symptom, from this description, is a Reduced energy level data cluster.

(F) Requires frequent rest periods: This usually occurs as a result of imbalance in the body's metabolism. Here, the body uses more energy than it produces; more anabolic processes (energy requiring) than catabolic processes (energy produced/released). This sign/symptom, from this description, is a Reduced energy level data cluster.
