EOC Review Pt. 1

Which is a primary function of a vacuole in a cell?

• Enzyme Production

• Protein synthesis

• Storage

• Reproduction

What determines the function of a specialized cell?

• The type of RNA in the cell

• the number of chromosomes in the cell

• the number of ribosomes in the cell

• the active genes in the cell

During which phase of the cell cycle does most cell growth occur?

• cytokinesis

• interphase

• prophase

• mitosis

In nature, which type of behavior causes animals to produce aggressive displays and sounds?

• imprinting

• territoriality

• conditioning

• habituation

What will most likely occur if the population of the world continues to increase at predicted rates?

• There will be an increase biodiversity as a result of improvements in technology

• There will be more rapid depletion of natural resources

• The human race will rapidly become extinct

• All human diseases will be eliminated

What will most likely happen if a nonnative species is introduced into a stable ecosystem?

• the native species will change their diet, and the ecosystem will remain stable

• the native species will move to another area, and the ecosystem will remain stable

• the native species will have to compete for resources with the nonnative species, and the ecosystem will become unbalanced

• the native species will share their food with the introduced species, and the ecosystem will become unbalanced

Why must DNA replication have to occur before a cell can divide by mitosis?

• to maintain the same number of chromosomes in the daughter cells as in the parent cell

• to cause one of the cells produced to have double the number of chromosomes as the parent cell

• to allow crossing over to occur in each of the cells produced

• to cause all of the cells produced to have half the number of chromosomes as the parent cell

A section of DNA has these bases

TAG CAG TAC

Which mRNA sequence is produced from this DNA section?

• ATC GTC ATG

• AUC GUC AUG

• AUG CUG AUC

• UTC GTC UTG

Which process can occur in both mitosis and meiosis?

• fertilization

• independent assortment

• gene mutation

• crossing over

How do some chemicals increase the risk of a person getting cancer?

• by causing cell mutations

• by causing a deficiency of vitamin D

• by causing an increase of toxins in the skin

• by causing a decrease in the immune response
