of the cell is:
A. Nucleus
B. Ribosome
C. Plasma membrane
D. Golgi apparatus
,Correct Answer: C. Plasma membrane
Rationale: Selectively permeable membrane regulates transport.
3. Ribosomes are composed of:
A. DNA and protein
B. RNA and protein
C. Lipids and RNA
D. Protein only
Correct Answer: B. RNA and protein
Rationale: Ribosomal RNA combines with proteins to form
ribosomes.
