Two students list characteristics of an organism:
-has cytoplasm
-has DNA in a nucleus
-has ribosomes
Based on the list of characteristics, Student A claims that the organism is prokaryotic, while Student B claims that the organism is eukaryotic. Which student is correct and why?
Student B because the cell contains a nucleus.
How do viruses disrupt normal cellular processes to cause disease?
Viruses use the cellular machinery of host cells to build products the virus needs.
