Multiple Choice

When the skin of a human is damaged,the existing skin cells around the area fill fill the area.How does this occur?

• Cell differentiation creates new cell types to heal the damaged area.

• Cell differentiation duplicates new stem cells to heal the damaged area.

• cell division duplicates existing skin cells in the area to heal the wound.

• cell division creates new skin cells from bone cells in the area to heal the wound.

Multiple Choice

Meiosis creates daughter cells from a parent cell.How are the daughter cells different from the parent cell?

• Have half the number of chromosomes and half of DNA as the original parent cell

• Have half the number of chromosomes and the same amount of DNA as the original parent cell

• Have the same number of chromosomes but only half of the DNA as the original parent cell

• Have the same number of chromosomes but double the amount of DNA as the original parent cell

Multiple Choice

Why are sugar molecules ideal for building a range of other macromolecules?

• Require energy to form and are attached to a range of other organic molecules.

• They contain carbon,hydrogen and oxygen which are the main parts in macromolecules.

• They can easily react with water to create all types of organic macromolecules.

• They are simple molecules that can be easily combined to create all types of macromolecules.
