PLEAS HELP! Can anyone tell me how plants survived the ice age

POSSIBLE ANSWERS:

Plants shut down their reproductive processes for thousands of years.

Seeds that are adapted to warm climates will germinate in greater numbers.

Stems will become taller and thinner over time.

Plants that could withstand the cold would reproduce in greater numbers.

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.
