Which of the following are key differences between eukaryotic and prokaryotic cells?
Eukaryotic cells have a nucleus, while prokaryotic cells do not.
Prokaryotic cells have membrane-bound organelles, while eukaryotic cells do not.
Eukaryotic cells are generally larger and more complex than prokaryotic cells.

How are plant cells and human cells different?
Human cells need food, but plant cells do not.
Human cells need energy, but plant cells do not.
Plant cells make their own food, but human cells do not.
Plant cells make their own energy, but human cells do not.
Once the virus is attached to our cell, the lipid layer of our cell and the lipid layer around the virus can merge because
Lipids attract lipids
Lipids attract proteins
The DNA instructs them to do this.
At the top left of this picture, you can see the spike protein of a virus fitting perfectly into a receptor site on our cells. Which sentence below is true?
Humans have receptor sites for viruses on our cells because we want viruses to invade our cells.
Humans have receptor sites for viruses on our cells because those receptor sites were made for a different purpose, but viruses evolved to be able to use them.
Which sentence is true about this picture.
It shows a virus being made.
It shows a virus entering the cell of a human or animal.
It shows a virus being destroyed by soap.

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.

against
up
down
with
