Answer - The chromosomes has to be crucially duplicated and it happens actively during the resting phase or interphase.
Reasoning - During the resting phase or interphase you call it, Is important to have the same exact DNA or Chromosomes to be duplicated. If the chromosomes did not duplicate during the interphase then the split of the cell would be unbalance and uneven and likely to cause defects.
Answer:
b. cause an increase in blood pH.
Explanation:
Carbonic anhydrases are zinc-containing enzymes that catalyze the reversible reaction of conversion between CO2 and bicarbonates (carbon dioxide hydration and bicarbonate dehydration). The conversion of bicarbonate to CO2 facilitates its entry into the cell. On the other hand, the conversion of CO2 to bicarbonate helps keep the CO2 inside the cell.
This enzyme is important in all living organisms for maintenance of acid-base balance (regulates pH ). For example, carbonic anhydrases lowers pH in the stomach by producing an acid.
<span>The right answer is D. males have only one copy of the X chromosome.
</span>Hemophilia is a rare hereditary bleeding disorder disease. The blood of hemophiliacs does not coagulate normally. Bleeding is not more important, but without treatment, they can be more frequent and last longer than normal. Hence the importance of good monitoring and good treatment.
<span>The 2 types of hemophilia A and B are recessive and X-linked, but a third of hemophilia correspond to a de novo mutation. It is observed that a man who wears the X is always affected by the disease (because he has only one X chromosome in its genome) whereas the woman is only a carrier (she has two X chromosomes, so it can carry a safe X and a mutated X without being attempted by the disease but can transmit it to her descendants). This must be taken into account for genetic counseling.</span>
4 is correct. In a wide expanse of space, gravity drew dust and gas together to create the solar system. The sun formed first from the vast material.
