Wich phase of the cell cycle is most affected by cytarabine

Biology
1 answer:
melisa1 [442]3 years ago
7 0

Its mode of action is due to its rapid conversion into cytosine arabinoside triphosphate, which damages DNA when the cell cycle holds in the S phase (synthesis of DNA). Rapidly dividing cells, which require DNA replication for mitosis, are therefore most affected.

Suppose a female began menstruating at age 12 and stopped menstruating at age 55. if she never became pregnant and her menstrual
Arte-miy333 [17]

Answer:

561

Explanation:

This is math so I got you.

This is just going to subtract 12 from 55 since we don't now when during her 12th year of age she started or when during her 55th year f age she ended.

55 - 12 = 43, so about 43 years.  Also not going to account for leap years.  So we are just going to say each year had 365 days.  so 43 years and 365 days per year = 15695 days.

If her cycles were each about 28 days we divide the total number of days by 28 and that tells us about how many cycles there were.

15,695 / 28 = 560.5 which I will round to 561

561 cycles means 561 eggs if my biology knowledge is as accurate as I think it is.

According to the general equation for conditional probability, if p (a^b')=1/6 and p(b')=7/12 , what is the value of p(a[b)?

P(B) = 1 - P(B') = 1 - (7/12) = 5/12 <span>P(A∩B)=<span><span>P(A∩<span>B′</span>)/</span><span>P(<span>B′</span>) </span></span>× <span><span>P(B)/</span>1

</span></span>Plugging values into the last equation we get: <span>P(A∩B)=<span><span>1×12×5 / </span><span>6×7×12 </span></span>= <span>542</span></span>
Now we can make use of the following formula <span>P(A|B)=<span><span>P(A∩B) / </span><span>P(B)</span></span></span><span> by plugging in the values that we have found.
</span>
<span>5/42 is the numerator and the denominator is 5/12.

The bottom (denominator) is P(B) which equals 5/12.

<span>P(A|B)=<span><span>5×12 / </span><span>42×5 = 6/210

6/210 = 2/7

Plz help me <br> WILL GIVE BRAINIEST
Illusion [34]

Answer:

The correct answer to this question should be a drup called antibiotics.

In our case, we need to look for something that helps us deal with bacteria infection, or in other words, treating diseases caused by bacteria. A drup that interfers with viral DNA is responsible for treating a kind of virus that basically  attack DNA to live. And I would consider the drug that moderates you use of sugar should be used to solve problem related to the amount of sugar in your body, maybe diabetes. Antibiotics is especially designed to kill bacteria, so it is the correct answer.

Chemoreceptors in the circulatory system detect changes in circulating pCO2. If CO2 concentrations get too high, the rate of ven
Levart [38]

Answer: The more active cells produce more carbon dioxide.

Explanation:

When the cells are constantly working the amount of oxygen consumed and more amount of carbon dioxide is released by the cells.

Chemo receptors in the circulatory system increases the ventilation so that more carbon dioxide can go out of the cell and more oxygen can get inside the cell.

This is because the more active cells more carbon dioxide and there is a sudden increase in the concentration of carbon dioxide which need to be corrected by the help of ventilation.
