Less

Explanation:

Hormones are chemical messengers produced by glands called Endocrine glands into the bloodstream in order to effect a change in a particular region of the body. Endocrine glands are those organs that secrete specific hormones e.g pancreas, pituitary gland etc.

When hormone concentrations are low in the blood, the gland will produce more amount of the hormone while the glands will produce lesser amount of hormone when there is a high concentration of hormones.

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.
