Mitosis results in the formation of...

• Two identical cells with a full set of DNA

• Two different cells with half of the original DNA

• Four identical cells with all of the original DNA

• Four different cells with half of the original DNA

Apoptosis is

• the process of programmed cell death

• the process of programmed cell growth

• the process of programmed cell birth

• the process of programmed cell regulation

Why do stomach cells function differently than skin cells?

• They contain entirely different DNA

• They use different genes in the DNA

What is cell differentiation?

• Process by which cells become UNSPECIALIZED

• Process by with cells become SPECIALIZED

• Process by which cells become old and DIE

• are undifferentiated

• never divide

What is gene expression regulation and why is it important in biology?

• Gene expression regulation is important in biology because it allows cells to mutate and become cancerous

• Gene expression regulation is not important in biology because it only affects non-essential functions

• Gene expression regulation is not important in biology because it has no impact on the organism's overall health

• Gene expression regulation is important in biology because it allows cells to respond to their environment, differentiate into specific cell types, and maintain proper functioning of the organism.

Fruit fly body cells have 8 chromosomes. After mitosis, you would expect a resulting fruit fly daughter cell to have -

• 16 chromosomes.
• 46 chromosomes.
• 8 chromosomes.
• 4 chromosomes.

What is the purpose of Mitosis?

• Growth of an organism and Repair of damaged tissue

• To help the body get rid of extra cells

• To increase the amount of classwork you have to do

• To get rid of the nucleus
