13. how do eukaryotic and prokaryotic cells differ?
only prokaryotic cells contain ribosomes
only eukaryotic cells come from pre-existing cells.
only prokaryotic cells come from pre-existing cells.
only eukaryotic cells contain membrane-bound organelles.
53. how are eukaryotic cells and prokaryotic cells similar?
both contain a plasma membrane, a nucleus, and ribosomes suspended within cytoplasm.
both contain a plasma membrane, cytoplasm, and circular DNA strands referred to as plasmids.
both contain cytoplasm, mitochondria, and small nuclei with pairs of linear chromosomes made up of DNA.
both contain a plasma membrane, cytoplasm, and ribosomes suspended within the cytoplasm.
Cell membranes are described as selectively permeable.
Four students were asked to explain what this means. Which one is correct?
Student 1: Cell membranes prevent all materials from entering the cell.
Student 2: Cell membranes only provide structural support for the cell.
Student 3: Cell membranes regulate which substances can enter and exit the cell.
Student 4: Cell membranes allow water and water-soluble substances to enter the cell.
A virus consists of:
RNA or DNA and a cell membrane
RNA or DNA and a protein coat capsid

There are four organelles that every cell has. The (a) controls what enters and exits the cell. The (b) make proteins for the cell. (c) is the jelly-like substance that suspends all the organelles, and (d) is a genetic material that instructs the cell what to do.
Which viral cycle takes the longest to show symptoms?
Lysogenic
Lytic
Which conclusion about HIV infection of a host cell is best supported by the diagram?
It takes place outside of living cells
It relies on the host cell to reproduce
It involves the process of meiosis
It requires carbon dioxide
Which of these describes a difference between viruses and cells?
Cells contain protein, and viruses contain only carbohydrates
Viruses have flagella, and cells only cillia
Cells reproduce independently, and viruses require a host to reproduce.
Viruses have membranes made of proteins, and cells have membranes made of nucleic acid.
How do vaccines protect us from viruses
The immune system develops antibodies in response the weakened virus
The weakened viruses attach to unaffected viruses in the host and interrupt the viral reproductive cycle
The rate of genetic mutation in the host is decreased due to the introduction of weakened viruses
the weakened viruses are unable to enter the host organism
Cancer creates abnormal cells by disrupting
the cell cycle
