A different flask of cultured cells contains 7 x 105 cells in 50 ml of medium. What is the concentration of cells (per ml) (0.5p

Nadusha1986 [10]

To find the average number of cell cultured per area, you have to divide the total cell count with the total area. The cultured cells contains 7 x 10^5 cells count in 50 ml of medium area. The number would be: 7 x 10^5 cells / 50ml= 0.14x 10^5 cells /ml= 1.4 x 10^4 cells/ml

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.

ioda

Answer:

Those organisms survive and maintain its population who are chosen by natural selection.

Explanation:

This statement means that when the population experiences a new set of environmental conditions, two things are happened i. e. the population either adjusts through natural selection or becomes extinct.
