Investigate the conditions required for seed to germinate. keep the dishes at room temperature for a week. explain your observations Dry cotton wool
wet cotton wool
covered with water

Explanation:

Starting off, the conditions required for a seed to germinate are:

Observations:

Dry cotton wool: Seeds placed here will not germinate. They will not show any changes since not all the the conditions are met. (There's no water)

Wet cotton wool: Seeds placed here will germinate since all the conditions required for germinations to take place are met.

Covered with water: The seeds will gradually start to expand. The oxygen which is dissolved in water does not enter the seed due to excess water thus preventing germination.

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.
