What happens when proteins and enzymes don’t control the cell cycle properly

The cell will begin to die and shut down.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

this is a good question! i'll do some research and come back when i have the answer!
