17. Before a cell can continue through the cell cycle there must be enough nutrients to support cell growth, the
DNA must be replicated, and the DNA should not be damaged.
18. (a) Binary fission and budding are both methods of asexual reproduction.
(b) Differences are that binary fission occurs in unicellular organisms and budding can occur in both
unicellular and multicellular organisms. Also, in binary fission one parent cell divides once into two
same-sized daughter cells, whereas in budding there may be repeated cell divisions and an unequal-size
outgrowth forms off the parent.
19. The main disadvantage of asexual reproduction is that the offspring are genetic clones. If the conditions
change or a disease appears it could wipe out the whole population
