What do parasitism, predation, and commensalism have in common? how are they different? (site 1)

Parasitism, predation, and commensalism, all three are common as only one species is benefited in process.

Explanation:

Parasitism is the symbiotic relationship in which one species benefits while other is harmed. Benefited species refers to parasites while harmed species known as the host.

Predation is the interaction of two same or different species where one kill or eat other, here also only one benefits.

Commensalism is a symbiotic relationship of two species where one benefits while other is unaffected.

Thus, parasitism, predation, and commensalism, all three are common as only one species is benefited in process.

answer; /// i do believe the correct answer is (

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
