1. Bacteria cells reproduce by binary fission, a type of asexual cell division. One evolutionary advantage of binary fission is to ensure survival of the population.

a

greater genetic variation in daughter cells

b

the ability to reproduce quickly

c

naturally greater resistance to disease

d

the ability to live under anaerobic conditions

membrane-bound organelles.

d

All of the above

Question 4

DNA replication occurs in the of cells.

a

nucleus : eukaryotic

Question 7

DNA replication ensures that each daughter cell will have all of the
