Explanation:

Homeostasis refers to the ability of an organism to maintain a stable internal state despite changes in external environment. In order to perform this process, some processes are required to be performed by the cell including:

- Photosynthesis, which is the process by which plants synthesize their food, helps the plant supply energy needed by the cell to perform it's function.

- Cellular respiration is the process of synthesizing energy (ATP) by the cell. Energy is needed by the cell for the numerous functions it carries out. Hence, cellular respiration is a homeostatic process.

- Diffusion is the process by which substance move from a region of high conc. to a region of low conc. until there is even distribution. Without diffusion, some materials cannot get into the cell, hence, it is a homeostatic process.

- Osmosis is the movement of water from a region with high water conc. to a region of low water conc. via a permeable membrane. The osmotic process is also a homeostatic one.

the answer is c) an oak tree

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
