Mutualism Humans release carbon dioxide that plants need; plants provide oxygen that humans need.

Explanation:

Parasitism =Tapeworms enter a human’s intestines through contaminated water and steal nutrients from the human.

Commensalism =Remora sharks attach themselves to whales by way of an adhesive disk on their dorsal surface. They then feed on the scraps from the whale’s meals

looks like youre on your own with this one buddy

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
