A student put an elodea plant in a test tube for 24 hours. For 12 hours, the plant received light; for the next 12 hours, the plant was kept in the dark.

The student measured the pH in both conditions. Explain why the water

became acidic at highttime. (You may use the formula for photosynthesis:

6CO, + 6H 0 -- CH, 20. + 602.)

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.
