The correct answer is the control variable. For example, if you want to measure how men and women like cats, you would present the same cats to all the people (that;s the constant variables) and gender is your control variable.

The lysosome functions in a cell like the _______ does in our bodies.
Troyanec [42]
Lysosomes remove waste at a cellular level.
They contain digestive enzymes, so they're like the digestive system.
The stomach digests food, so lysosomes could be considered like the stomach.
But then again, so do the intestines, small and large.
Since the stomach doesn't also work to remove waste though, I'd say the answer is probably large intestine, which finishes the digestive process and removes waste material.

satela [25.4K]

Explanation:

Biome and the ecosystem are the words that are sometimes applied interchangeably to explain a particular kind of environment.

The biome represents the geographical region that has the same kind of ecological atmosphere, climate and mostly consistent collection of the species and it is made of a large number of ecosystems.

An ecosystem represents a particular element of the biome and a species that nearly interact in it.

Thus the biome is the collection of various types of ecosystems.
