Which is an example of osmosis? *
Potassium ions moving in and out of an animal cell

Carbon dioxide moving into leaf cells of a plant

Oxygen moving into the bloodstream from the lungs

Water moving into the root cells of a plant

equal distribution i think.

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate
