1) cover cells
2) cell membrane, Cytoplasm
3) Protein synthases
4)The movement of molecules from a higher concentration to a lower concentration
5) 6 marker
factors affecting photosynthesis: light intensity and temperature
0.04%=16 units
percentage increase was 25%
cell division question = 4
ethical problem = killing life
good thing = healthier baby
Possibility of next child having diseases = 1/4

I have a friend who makes a strong case for the cell division question actually being 15, because technically in order to obtain 16 cells from 1, the total number of divisions is 15.

The specification backs this up as it refers to two divisions producing four daughter cells.

1 parent cell splits into 2 daughter cells. These 2 cells then split to make 4. The 4 then split to make 8. Then the 8 split to make 16.

We have discussed this answers among a group of friends and all of us agree that this answer is technically correct, despite all of us but him having put 4 and not 15. Nevertheless, we believe that the mark scheme will be looking for 4, despite the technical answer being 15.

would 15 units be right?
