Please help me.. ty if you do Chloe is studying the effect a certain kind of fungus has on bacteria. Which of the following could be her hypothesis?
"I notice that when a certain fungus is present in a bacterial culture, the bacteria do not grow".
"Based on my tests, I realize that this fungus kills bacteria".
"I predict that the bacterial cultures in which I place this fungus will not grow".
"I propose that this fungus somehow kills bacteria."

I propose that this fungus somehow kills bacteria

Explanation:

you rule out 2,3 because a hypotheses has not yet been proven therefore it is not certain

while in 1 in some cases the bacteria can also over power and kill the fungi using genes

but I chose 4 since fungi lack chloroplasts so they feed of ready made food and bacteria can be autotrophic therefore can manufacture food and so the fungi digests the bacteria in the process of trying to acquire the food since they don't have cell walls I guess
