1. In a wx bacterial cell, the DNA is in t
wx wx wx wx wx wx wx
he:
A) cell envelope.
wx
B) cell membrane.
wx
C) nucleoid.
D) nucleus.
E) ribosomes.
2. A major change occurring in the evolution of eukaryotes from prokaryotes was
wx wx wx wx wx wx wx wx wx wx wx
the
wx
development of: wx
A) DNA.

3. In eukaryotes, the nucleus is enclosed by a double membrane called
wx wx wx wx wx wx wx wx wx wx wx
the:
A) cell membrane. wx
B) nuclear envelope. wx
C) nucleolus.
D) nucleoplasm.

4. The dimensions of living cells are limited, on the lower end by the minimum num
wx wx wx wx wx wx wx wx wx wx wx wx wx wx
ber of biomolecules necessary for function, and on the upper end by the rate of di
