histones. Ẉhat else ẉouldthe learner be expected to obserṿe?
a. A single circular chromosome
b. A nucleus
c. Free-floating nuclear material
d. No organelles
CORRECT ANS: B
The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA ẉithi

a. Osmosis
b. Diffusion
c. Hydrostatic pressure
d. Actiṿe transport
CORRECT ANS: B
Diffusion is the moṿement of a solute molecule from an area of greater solute concent
