SHORT ANSWER
36. ANS:
Cell division (mitosis) is used to repair damaged tissue by replacing injured cells.

37. ANS:
Skin cells are always being replaced by cell division (mitosis). As long as they are replaced as fast as they
are shed, they cannot be worn down.

38. ANS:
Nuclear DNA is exclusive to an individual; no two people have the same nuclear DNA, except identical
twins. Mitochondrial DNA comes from the mother; children with the same mother will have the same
mitochondrial DNA. Mitochondrial DNA is not specific to an individual.

39. ANS:
Chromosomes are made up of DNA (and protein). A section of DNA that codes for a protein is a gene.
Therefore, genes are found in the chromosomes.

40. ANS:
Before mitosis, DNA is replicated; the cell has a double set of all genes. When the cell divides, one set of
chromosomes goes to one of the daughter cells, while the other set goes to the other daughter. Since both
daughters receive a copy of the original chromosomes, both daughters are identical.

41. The advantage is that new habitats may be easier when an individual does
not need to find a mate to reproduce.The disadvantage is that all of the offspring
are genetically identical and may not have the genetic variation to survive in new
or different conditions.
42. What 3 instructions does Dna give a cell?
-How the cell functions
-what the cell produces
-when the cell dies.
43. Describe 3 advantages and 3 disadvantages of asexual reproduction
Advantages
●
●
●
●
Population can increase rapidly
Only 1 parent is needed
More efficient since you don’t
need a mate
Faster than sexual reproduction
Disadvantages
●
●
●
Lack of diversity
Unable to adapt to the changing
environment
A change in environment could eliminate
the entire species
44.)
Internal Fertilization
External Fertilization
Definition
When the sperm and egg join inside the
parent
When the sperm/egg join
outside parents
Example
Birds
Fish
Advantages
●
●
Embryo protected from predators
Offspring more likely to survive
●
●
Disadvantage
s
●
●
Fewer zygotes produced,
resulting in fewer offspring
More energy required to raise,
care for offspring
●
●
Very little energy
required to mate
A large number of
offspring produced
Many gametes will not
survive
Many eggs will not be
fertilized
