Mammals that live in the arctic ocean have a large amount of blubber, which is a fatty tissue just beneath the skin. which statement best relates why these animals have so much blubber? a.)lipids in blubber insulate the animals from cold water. b.)proteins in blubber the animals move to stay warm. c.)carbohydrates in blubber provide all the energy that the animals need to stay warm. d.)nucleic acids build the lipids in blubber, which keep animals warm by regulating cell activities.

The right option is; A.)Lipids in blubber insulate the animals from cold water.

Blubber is a thick layer of fat (adipose) tissue that is located under the skin of all marine mammals such as polar bear and whales. Blubber insulates heat, stores energy, makes animals float in water. The adipose tissue in blubber has a relatively low thermal conductivity and it insulates the animals by keeping them warm in cold environments.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
