In what stage of meiosis is crossing over most likely to occur?
a. prophase i
b. anaphase ii
c. metaphase i
d. prophase ii

Option A, Prophase I

Explanation:

It is during the prophase I stage of meiosis when chromatic tetrads exchange their chromosomes followed by disappearance of  nucleus envelope.

In Meta phase I,  the chromatic tetrads arrange themselves along the equator.

In Anaphase II, sister chromatids (within each chromosomes) seperate from each other and move towards the opposite end of the cell.

In Prophase II, haploid cells formed in meiosis I condenses their chromosomes.

Hence, option A is correct.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.

the answer is d. none of the above
