How many cells do miTosis produce?
3.
What is the difference between asexual and sexual reproduction?
a)
Asexual produces genetic diversity, but sexual does not

Asexual the offspring are genetically different, sexual reproduction are all clones of each other 
4.

All of the offspring of an organism have the same genetic material, which is identical to the parent organism. From this, we can conclude that this organism - (a)

When comparing the offspring of sexually and asexually reproducing organisms, we would expect the genetic material (DNA) of the sexually reproducing organism to - (a)  

Choose from the below words
contain fewer mutations
be lesser in quantity
be simpler overall
show more variation
6.

Takes only one mate to reproduce and takes a shorter time to reproduce
8.
What are some of the facts about sexual reproduction?

Why is reproduction necessary?
a)
The environment could change
b)
Because it requires very complex structures
c)
Increases genetic variability of species
d)
The survival of the species depends on the ability for organisms to reproduce
