(a)
Milly observed that her lettuce plants wilted after several days of drought, but after a a downpour of rain, the leaves began to swell. What cellular process caused the swelling in the lettuce plants?
(a)
Milly observed that her lettuce plants wilted after several days of drought, but after a a downpour of rain, the leaves began to swell. What type of osmosis is this an example of?
hypertonic
hypotonic
isotonic
Protein molecules can be broken down into smaller components called _.

The diagram reveals that lipids and proteins are both parts of cell membranes. They have different functions because -
Lipids stiffen the cell membrane; proteins attach to ends of lipids
Lipids move chemicals; proteins store water
Lipids remove nucleic acids; proteins hold the cell membrane together
Lipids hold the cell membrane together; proteins move chemicals across the cell membrane

This picture shows molecules of red dye that have moved. What is this type of movement called?
Osmosis; the water molecules are moving from high concentration to low
Diffusion; the dye molecules are moving from low to high concentration
Diffusion; the dye molecules are moving from high to low concentration.

Viruses use cell machinery to build products the virus needs.
Viruses release large amounts of energy into the cell, causing increased growth rates.
Viruses release antibiotics that destroy the cell membrane so more viral particles can be released.
