Many molecules are moved through the body by . provide structure for plants. determine what people look like. Cells are surrounded and protected by . speed up chemical reactions in the body. Hemoglobin, a protein, is built by . The human body is insulated by

1) facilitative diffusion use a special transport Proteins to move molecules across the membrane that cannot pass through on their own.

2) carbohydrates

3) Nucleic acids: The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid(DNA) encodes the information the cell needs to make proteins.

4) lipids

5) proteins

6) hemoglobin: Hemoglobin is a protein in your red blood cells that carries oxygen to your body's organs and tissues and transports carbon dioxide from your organs and tissues back to your lungs

7) lipids: Lipids designate fats, oils, steroids and waxes found in living organisms. Lipids serve multiple functions across species, for energy storage, protection, insulation, cell division and other important biological roles.

Explanation:

These are right ^ the one the other person gave i got wrong

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.
