The factor being tested is the variable. There are two types of variables, independent and dependent. The independent variable is the factor being changed by the scientist or the person controlling the experiment. The dependent variable is the thing that gets changed due to the changing of the independent variable. The dependent variable cannot be changed physically by the person doing the experiment.

Answer:

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

What part of the rotifer is responsible for crushing food?
frozen [14]

Answer:

Rotifers are specialists at living in habitats where water dries up regularly.

The Monogononta, which have males, produce fertilised 'resting eggs' which can resist desiccation (drought) for long periods.[11]

The Bdelloids, who have no males, contract into an inert form and lose almost all body water, a process known as cryptobiosis. Bdelloids can also survive the dry state for long periods: the longest well-documented dormancy is nine years. After they have dried, they may be revived by adding water. In this, and several other ways, they are a unique group of animals.[12]

Explanation:

The front has a ring of cilia circling the mouth. This gave the rotifers their old name of "wheel animalules". There is a protective lorica round its body, and a foot. Inside the lorica are the usual organs in miniturised form: a brain, an eye-spot, jaws, stomach, kidneys, urinary bladder.

Rotifers have a number of unusual features. Biologists suppose that these peculiarities are adaptations to their small size and the transient (fast changing) nature of its habitats.
