A scientist places four identical cells into four different liquids, each with different concentrations of magnesium. Cell Description of Liquid Result W Slightly more magnesium than the cell Took in magnesium X The least amount of magnesium Took in magnesium Y Slightly less magnesium than the cell Took in magnesium Z The most amount of magnesium Took in magnesium Which shows evidence of active transport?

The correct option is Z

Explanation:

Active transport can be described as the movement of molecules against a cell's concentration gradient; meaning the movement of molecules across the cell's membrane from a region of lower concentration to a region of higher concentration. From this, it can be deduced that to have active transport in the description in the question, the "body" (the cell or the liquid) with the most amount of magnesium took in more magnesium (showing movement against concentration gradient as the magnesium moved from the least side to the most side). Thus, the correct option is Z

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.
