2
Q
GROWTH
A
mitosis will occur to produce new cells
3
Q
REPAIR
A
mitosis will occur to replace damaged or dead cells
4
Q
CLONING
A
mitosis will occur to make identical copies
5
Q
ASEXUAL REPRODUCTION
A
mitosis will occur to produce offspring that is genetically identical to the parent
6
Q
DIPLOID
A
normal human body cell as a result of mitosis that has two of each chromosome, resulting in 46 chromosomes

Q
DARWIN’S THEORY
A
- individuals in a species show a range of variation caused by differences in genes
- individuals with characteristics most suited to te environment has a higher chance of survival and to reproduce
- these genes that allow organisms to survive are passed to their offsprings
