Answer:
10 chromosomes
Explanation:
<u>Ten (10) chromosomes</u> would be found in each cell of Arabidopsis thaliana during prophase.
The prophase stage represents the first stage of the mitotic division immediately after the interphase. A diploid cell has 2n number of chromosomes and the ploidy level of a cell remains intact throughout the interphase to the prophase stage of mitosis.
<u>At the prophase, the chromosomes of a cell only condense and become visible under the microscope. Each chromosome is seen as being consisting of two sister chromatids joined together by a structure known as the centromere. </u>
<em>Hence, the number of chromosomes in the cells of Arabidopsis thaliana would remain the same even at the prophase stage of mitosis.</em>
During the first one to two months of life, infants are incapable of deep sleep (they do not have trouble falling asleep but they do not generally stay asleep for very long stretches). This happens because infants can’t make the difference between night and day - they do not yet have a circadian rhythm. Around six weeks, the hormone melatonin is produced (pineal gland) and it helps establish a normal sleep-wake cycle.
