FALSE
The ancient earth did not contain much oxygen. - correct answer. TRUE
Why is it important to know the limitations of technology? - correct answer. Unable
to view live cells under SEM magnification, Microscopy is limited with magnification.

TRUE
The cytoskeleton gave rise to the nuclear envelope. - correct answer. FALSE
The presumed first step in the transition of the primitive, proto-prokaryotic cell into the
primitive, proto-eukaryotic cell was the loss of the cell wall.
Group of answer choices - correct answer. FALSE
List one limitation of the cell culture technique. - correct answer. -Not all cells grow
in culture
-Cells lose their histotype (in vivo shape) and 3-D structure of tissue is changed
-Metabolism likely changes
It is presumed that the peroxisomes evolved in these primitive, proto-eukaryotes to
remove oxygen, which was toxic to the primitive cells. - correct answer. TRUE
A normal cell is ____________and _________________for growth. - correct answer.
Mortal
Anchorage-dependant
Motility improved the fitness of these early cells because:
It allowed them to make a nuclear envelope.
It caused them to acquire ribosomes.
It allowed them to move away from predators and towards food.
Two of the above.
None of the above. - correct answer. It allowed them to move away from predators
and towards food
