A student collects several plants and pebbles from a riverbank, places them in an aquarium, and records observations for 15 days.

Which criteria does the student use as the basis for the classification? A ability to grow B ability to move C ability to reproduce D ability to respond to stimuli

nucleus

would be most reasonable answer tbh

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.
