The animal cell has a nucles while the red blood cell does'nt have any
During protein synthesis the cell uses information from messenger RNA
Id say D
as the tide range may affect at how close to the sea a species can live without being submerged by the tide
length of exposure can determine what species can live on the shore as they may be submerged underwater for different periods of time
wave action can also determine what species can live on rocks as depending on the action it will favour diffrent species
hope that helps
