Which of the following statements is true?
a. Linear chromosome structures observed in a karyotype are actually pairs of sister chromatids.
b. Prokaryotic and eukaryotic cells divide through binary fission.
c. Because chromosomes of prokaryotes are smaller than eukaryotic chromosomes, prokaryotic nuclei are also smaller.

Which of the following statements about cell division in prokaryotes and eukaryotes is correct?
a.
In prokaryotes, all cells divide if conditions are favourable; in eukaryotes, only a few cells divide, and they do so according to a developmental program
b.
After cell division, the daughter cells are genetically identical in prokaryotes but genetically different in eukaryotes
c.
In prokaryotes, only a few cells divide to ensure survival of the colony without depleting too many resources from the environment
d.
The process of segregation is more complicated in prokaryotes than in eukaryotes
e.
Reproductive signals for initiation of cell division are intracellular for prokaryotes and extracellular for eukaryotes
