Biology quiz
Please read the following questions and answer them:
1) Explain thebenefit of having tiny small sized cells instead of few large ones.
2) List the common features of cells.
3) Explain the arrangment of the lipid bilayer molecules in the cell membrane.
4) What is the cell theory?
5) Compare between eukaryotes and prokaryotes (not less than 3 points)
PLEASE DONOT SEND THE ANSWERS AS ATTACHED FILES AS I HAVE A PROBLEM WITH OPENING ANY DOCUMENT THAT IS NOT 2007 .....
SO JUST PLEASE WRITE THE ANSWERS AS AN EMAIL AND SEND (OR ELSE I WON'T BE ABLE TO CORRECT SOME OF THE QUIZES)
