Cell Transport virus Review bustabio

What is the function of the cell membrane?

• maintain homeostasis by carrying the genetic info

• maintain homeostasis by creating proteins

• maintain homeostasis by controlling transport of molecules in and out

• maintain homeostasis by making energy

Both prokaryotes and eukaryotes have which of the following?

• cell membrane

• chloroplast

• nucleus

• ER

Gas exchange in the alveoli of your lungs is considered simple diffusion because?

• The oxygen and Co2 are small molecules that need no energy to transport

• The oxygen and Co2 are big molecules that need no energy to transport

• The oxygen and Co2 are small molecules that need energy to transport

• The oxygen and Co2 are big molecules that need energy to transport

Your stomach absorbs different nutrients like sugar and salts. These are large molecules that go from high to low concentration and travel through a protein channel. What type of transport is this?

• active transport

• facilitated diffusion

• osmosis

• simple diffusion

A salt water fish constantly absorbs water so when it is placed in freshwater, it absorbs too much water and dies. What would happen to a freshwater fish if it is put in a saltwater aquarium?

• It would absorb too much water and die

• It would lose too much water and die

• It would neither absorb nor lose water

Blood is naturally a little bit salty (0.9%). This is why saline solutions can be used in the hospital. This means that the saline solution must be ____________ with the blood.

• saltier, hypertonic

• less salty, hypotonic

• equal, isotonic

Tom drank way to many gallons of pure water. He feels terrible and all of his cells are swollen. Tom needs something to pull water out of his cells. What should he do?

• Eat more salt, the salt will suck the water out

• Drink more water, the water will drain out

In osmosis, water goes from High water to low water concentration. In osmosis water will move to the side that has more solute concentration. Which way will the water move in this picture?

• inside of cell to outside of cell

• outside of cell to inside of cell

• the water won't move

We don't know the water concentration but we know that water will move to the side that has more solute and less water? Which way will water move in this picture?

• water will move inside the cell

• water will move outside the cell

• water won't move

We don't know the solute concentration but we know that water moves from high water to low water and from low solute to high solute. Which way will water move in this picture?

• water will move inside the cell

• water will move outside the cell

• water won't move
