The salinity of a small inland lake has recently started to increase. researchers are planning to study the lake over several decades to investigate how freshwater organisms survive significant changes in their natural habitat. which of the following physiological mechanisms will the researchers most likely observe among the surviving organisms in the lake? a. prokaryotic organismus will use various menchanismus to counteract swelling of cells as a result of increased water uptake. b. single- celled organismuss will use various mechaismus to counteract the increased flow of water from cells to the entvironment. c. eukaryotic organismus will use various mencahismus to counteract the diffusion of positively charged ions across the cell membrane. d. eukarytic organismus will use mechanismus to counteract diffusion of swelling of scells charged ions of increased water uptake. e. multicellular organismus organismus will use various mechanismus to counteract the loss of cell adhesion as a result of calcium deficiencies.

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

that is true   : ) hope this you

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
