Chromosomes, which are found in the nucleus of a cell, contain genes. A gene is basically a section of DNA, which carries some type of coding for particular protein. The structure in which all genetic information can be found is your DNA (short for D<span>eoxyribonucleic Acid). (I don't know if the first part helped?).</span>
The limitation is that she can't test is on humans for ethical reasons.

Explanation:
One of the ways in which a cell maintain homeostasis is by regulating what goes in and out of the cell through the cell membrane (which is a semi-permeable barrier). The amount of water is highly regulated by the cell in this case so as to regulate osmosis (movement of water molecules from a region of higher concentration to a region of lower concentration). Other substances regulated are oxygen and carbon dioxide.
NOTE: The cell <u>does not create water molecules neither does it use carbon dioxide to maintain homeostasis</u>, it rather regulates these two compounds.

I'm going to guess on your unmentioned following and say that it is not derived from beans, eggs, milk, and so on because a lipid is an oily, greasy and waxy molecule found inside of a body. Lipids can normal be extracted from cells using non-polar solvents such as chloroform or benzene. Hope this helped!
