An insecticide kills most of the ants on a plant. Over time, it is determined that the insecticide is not as effective for killing ants. Which statement best explains this observation?

• The ants killed initially by the insecticide were genetically the same as the surviving ants.

• The ants killed initially by the insecticide had thinner cell membranes than the surviving ants.

• The ants that survived were younger than those that died as a result of the insecticide.

• The ants killed by the insecticide and the surviving ants were genetically different.

A contractile vacuole helps protists eliminate excess liquid. This is a “pumping" process which reduces pressure inside the cell and prevents the cell from bursting. What is most likely the source of energy for this process?

• lipids

• ATP

• ribosomes

Identical twin girls are separated at birth and cared for by two different families. After twenty years, the twins have different heights and weights. What is most likely the cause of these differences?

• One twin had a genetic condition that prevented her from growing tall.

• The DNA of one twin was different from the DNA of the other twin.

• Each twin was provided a different diet and physical activities.

• The proteins made by one twin were different than the proteins made by the other twin.

What is the function of a restriction enzyme?

• to control the movement of proteins into a cell

• to regulate blood sugar levels

• to produce hormones that regulate digestion

• to cut DNA at a specific nucleotide sequence
