Answer:
Carbon based molecules have 3 main structures which are
straight chain
branched chains
rings
Explanation:
The structure or shape of carbon can be a straight chain, branched chained or in the form of rings. Examples of straight chain carbon includes propane, butane and pentane. Examples of branched chain carbons include members of the alkyl group like methyl and ethyl. Ring shaped carbons form structures in the form of rings like benzene which forms a six carbon ring. All these structures are made and dependent on the ability of carbon molecules to form four covalent bonds. Enormous, complex molecules can be formed by the binding of carbon chains to carbon rings. The carbon based molecules are very important as they are the basic buiilding blocks of life. Many important molecule like the DNA, RNA, lipids are made up of carbon atoms.

Sea lions are noisier, seals are generally quieter, seals lack external ears, while sea lions have small flaps for ears.
2) The concentration of O2 will increase inside the cell.
The cell will want to reach equilibrium, meaning that there should be an equal number of oxygen inside and outside the cell. In the picture, more oxygen is shown outside the cell than inside so oxygen will flow into the cell until it has reached equilibrium. Therefore, the concentration of O2 will increase in the cell.
Hope this helps!!
