1
Meiosis is different in mitosis because:
DNA condenses into chromosomes
the genetic information is received from the parent cell
it is necessary for life
more than one daughter cell is produced
2
External fertilisation does NOT require:
a moist (fluid) environment
appropriate environmental conditions
parents to raise offspring
a large number of gametes to increase success rates
3
Which kind of pollination is most likely used by plants with bushy or feathery appendages?
wind pollination
mammal pollination
bird pollination
insect pollination
4

Sexual reproduction
All of the above
15
Internal fertilisation does NOT require:
appropriate timing of male/female cycles
a moist (fluid) environment
close proximity of an appropriate mate
a large number of gametes
16
