Why don't cells just stretch when you grow, instead of making copies of themselves?

• The muscles in the cells can't stretch that far.
• The cell won't be able to bring in food fast enough or get waste out fast enough.
• The cell membrane doesn't like the feeling of stretching.
• The lysosomes don't want to work so hard.

If you were able to count the number of chromosomes of a body cell in every organism, you would find:

• Every organism has the same number of chromosomes
• Each organism has a specific number of chromosomes that are associated with it.
• There are different numbers of chromosomes in different cells of the same organism.
• There is no way to determine the number of chromosomes in any organism except humans.

Why is sexual reproduction better than asexual reproduction?

• It gives an advantage to organisms to be different than the rest, if the environment changes.
• It is better for all organisms to be the same.
• It happens faster.
• It helps skin cells divide faster to heal wounds.

Which is a disadvantage of sexual reproduction?

• Sexually reproducing organisms reproduce too quickly
• Sexually reproducing animals must find a mate
• Sexual reproduction does not allow organisms to adapt
• Sexually reproducing organisms are identical to their parents

Why do we need meiosis?

• To double the number of chromosomes going into sex cells
• To halve the number of chromosomes going into sex cells
• To triple the number of chromosomes going into sex cells
• To not change the number of chromosomes going into sex cells
