A contractile vacuole helps eliminate wastes in a protist by pumping out wastes. This pumping reduces pressure and keeps the cell from bursting. The energy needed for this "pumping" most likely comes from?

• DNA

• Lipids

• ATP

• Ribosomes

• Protein synthesis

• Storage

• Reproduction

What do prokaryote and eukaryote cells both contain?

• membrane bound organelles

• linear chromosomes

• a nucleus

• cytoplasm

Which best explains why muscle cells are different from blood cells.

• A mutation happens in muscle cells but not in blood

• Different genes are activated in muscles cells and blood cells

• Muscle cells experience different environmental conditions than blood cells.

• Muscle cells are produced by the brain while blood cells are produced by the heart

Which of these cells in the human body is specialized to transport oxygen throughout the body?

• 
• 
• 
• 

A freshwater plant is placed in a container of saltwater. What will most likely happen to the cells of the plant?

• They will swell bc water moves in

• They will swell because salt moves in

• They will shrink bc water moves out

• They will shrink bc sald will move out

Which is the best evidence that a cell is using active transport to move a substance across its membrane?

• Substances are moving rapidly across the membrane

• ATP is being rapidly consumed near the cellular membrane

• Substances are moving from high to low

• Substances are moving through channels in the membrane

This diagram shows a plant cell. Which parts does a plant cell ha:ve that an animal cell doesn't.

• A and B

• B and C

• A and C

• C and D

The picture shows a variety of cells from the same organism. How can cells from the same organism have such different shapes and functions?

• As cell differentiate, the DNA changes so each cells has different DNA at maturity

• Mutations in the cell lead to new combinations of DNA

• During differentiation, different parts of the DNA in each type of cell is activated causing them to have different functions

• During differentiation, different types of cells produce proteins that destroy nonactive DNA
