Its easy i just need a useful hypothesis should be testable, meaning that an experiment can be conducted that provides evidence either in support or against the hypothesis. a proposed hypothesis is poorly stated if any evidence that can be gathered does not its evaluation. different people might reach different conclusions about the taste of a tomato, or whether or not it was easy to raise, or the properties of the "best" tomato.

The tomato example is not a good hypothesis because the responses are subjective - not measurable. A good hypothesis has to have something that is measured- so you could consider a hypothesis on tomatoes around the amount of lycopene (the red color) And how much sugar/g of tomato there is (so the redder the sweeter kind of idea but is measurable)! Hope this makes sense.

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.

a scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. a scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.
