two. pink. flowers are crosswd there are 40 offspring which consist of red flowers
The correct answer is 'If molecules are small enough, then they can pass through the semipermeable membrane because they can cross the semipermeable membrane from their small pores or openings'.
The semipermeable membrane is permeable to few molecules, and the smaller molecules pass through the molecules from small pores present in the semipermeable membrane. The size of the big molecules are large, so, they cannot cross through semipermeable membrane.

Dissolved O2 conc. in flask with algae will be higher since photosynthesis produces O2.
For number 1 the first arrow is the cell wall, the second is the membrane, and the last arrow would be the cytoplasm
For number 2 they are in distilled water Bc they are remaining the same and not shrinking up
For three draw the cells smaller salt water sucks the water out of them
For four they get smaller because the salt has a higher concentration making the water leave the cell. Once water has left the cell begins to shrink
