Which description best fits the activity of a cell during interphase?
katovenus [111]

Answer:

<em>The correct option is A) The cell carries on metabolism.</em>

Explanation:

During the interphase, the cell tends to carry out its normal cell activities and it prepares itself for the cell division process during the interphase. It synthesizes proteins etc which will be required for cell division during this phase. The cell becomes enlarged during this phase. A cell tends to spend most of its time in the interphase. Hence, option A is correct.

Other options, like option C, cannot be considered to be true because the process of cell splitting does not occur during the interphase, It happens during the process of cytokinesis.

Suppose that a diploid cell contains 8 chromosomes (2 n = 8). How many different combinations in the gametes are possible?
zhenek [66]

Answer:

16

Explanation:

A diploid organism that produces gametes will undergo meiosis to do so. Meiosis reduces the chromosomal number in the gametes by half. Hence, each gamete will have 4 chromosomes (haploid,n). Crossing-over will likely occur during the meiotic process leading to recombination in the arrangement of chromosomes in the gametes.

If this occurs, a mathematical expression of 2^n is used to determine the number of possible combinations, where n is the number of chromosomes in the gamete.

Hence, 2^4 = 16 possible combinations of chromosomes in the gamete.
