Q. Which of the following are true concerning living things? Check all that apply. (2 pts) 1: They contain a vital force absent in nonliving things.
2: They are composed of molecules that contain carbon-carbon bonds.
3: They undergo chemical reactions to use energy they acquire from the environment.
4: They do not require catalysts to sustain their living state.

Explanation:

2 They are composed of molecules that contain carbon-carbon bonds.  

3. They undergo chemical reactions to use energy they acquire from the environment.  

Living things includes all the organisms that display features which make them distinct from non-living organisms. The living organisms  have an organized structure, they are composed of cells, they require energy to survive or sustain existence, they are able to reproduce and they exhibit ability to grow.

They are composed of molecules that contain carbon-carbon bonds: Carbon is the main component present in all living things. They make up the organic biomass of these living organisms.

They undergo chemical reactions to use energy they acquire from the environment: The plants traps sunlight energy and converts it into food and lastly into chemical energy in the form of ATP. This ATP is used as a energy reservoir for metabolic processes occurring in the plants. Therefore, energy is generated after chemical reactions.

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.
