I go with Ice Core examples since early sociteties probably didn't have Written Records or maps, and tree rings would only tell if they were fossilized. I hope this helped :)

A cell undergoing cell division identifies a chromosomal misalignment. How does this normally affect the progress of the cell cy

telo118 [61]

When a cell undergoing cellular division identifies that a chromosome misalignment had taken place the cell cycle stops until the error it's corrected.

Option two of the question states that the cell cycle will proceed uncontrollably, this is not the case for the error at hand. Although this can be a problem for cells and leads to the appearance of cancer, it is not caused by chromosome misalignment. As is the case with options 3 and 4.

The stop or delay in the cell cycle is what normally takes place in these situations. This stoppage is done by the spindle checkpoint, which prevents duplicate chromosomes from separating.

During this time, the error it's corrected. If a cell is not able to correct the error at this time, many situations can follow. However, the most likely is that the cell will undergo a programmed cellular death.

Increasing the volume of air that reaches the alveoli and takes part in gas exchange will cause blood pH to:

Karolina [17]

Answer:

B. increase, because the partial pressure of CO2 in the blood will decrease.

Explanation:

The presence of carbon dioxide gas in blood imparts H+ ions due to its reaction with H2O and thereby, lowers down the blood pH.

When more air reaches alveoli, the rate of gaseous exchange is increased. More of the carbon dioxide is removed from the blood and is released out of the body via exhalation.

Removal of carbon dioxide from blood would increase the pH of the blood since the partial pressure of CO2 in the blood would decrease.
