A somatic cell from a corn plant normally contains 20 chromosomes. How many sister chromatids would that cell contain during g2 of the cell cycle?

Total 40 sister chromatids

Explanation:

A cell cycle comprises of various phases that includes G1 phase, S phase, G2 phase, Mitosis and cytokinesis.

As G2 phase occur after DNA duplication so each chromosome in this phase contains two sister chromatids that's why the corn plant with 20 chromosomes would contain 40 sister chromatids in G2 phase.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
