a
Some O2 will enter the cell.
b
Some CO2 will leave the cell.

Some H2O will leave the cell.
Question 3
Herpes simplex and HIV are excellent examples of which of the following?

a
antigens
b
bacteria
c
immunity
d
virus
Question 4
Why do viruses need living hosts, such as bacteria or eukaryote cells?

a
Viruses depend on a host cell because they lack their own DNA or RNA.
b
The host cell is the source of food for the virus.
c
Viruses depend on the host cells that they infect to reproduce/replicate.
d
Viruses have a cellular structure which never requires a host.
Question 5
Summarize the lytic cycle.

10.7A: The Lytic Life Cycle of Bacteriophages - Biology LibreTexts

a
The viral DNA incorporates itself with the host cell’s and replicates whenever the host cell replicates itself.
b
A virus injects its genetic material into the host cell, copies itself using the host's structures and resources, and then forms new viruses that burst out of the host cell.
c
A virus copies its own genetic material and then splits its cell membranes in half to form two identical viruses.
d
A virus lays eggs on the host cell’s protein coat, which then hatch and move on to infect other cells.
Question 6
Review the responses below; then SELECT ALL the reasons why we use scientific models.

a
Models are always expensive.
b
Models are used when systems are too expensive, expansive or impossible to use.
c
Models help you understand complex systems.
d
Models allow exploring very small or very large systems.
Question 7
Which statement best describes the plasma membrane of a living plant cell?
The plasma membrane of a plant cell is

a
designed to allow for the free flow of all protein substances to move into and out of the cell.
b
composed of two layers of proteins and carbohydrates only.
c
composed of two layers of proteins with floating molecules of lipids only.
d
designed to allow certain substances to enter and certain substances to exit the cell.
Question 8
How do the Golgi apparatus and vesicles interact in an animal cell?

a
The Golgi apparatus synthesizes proteins, and the vesicles package the proteins for transport in the cell.
b
The Golgi apparatus transports proteins, and the vesicles control the transportation of the proteins in the cell.
c
The Golgi apparatus degrades proteins, and the vesicles synthesize replacement proteins in the cell.
d
The Golgi apparatus packages proteins, and the vesicles transport the packages to various locations in the cell.
Question 9
How do ribosomes and the Golgi apparatus interact to maintain homeostasis?

a
Ribosomes synthesize proteins that are sorted and packaged by the Golgi apparatus.
b
Ribosomes store molecules that are converted into usable energy by the Golgi apparatus.
c
Ribosomes transport proteins and enzymes that are synthesized by the Golgi apparatus.
d
Ribosomes store liquids and other waste products that are created by the Golgi apparatus.

Answer 1

Here are the answers to the questions based on your provided queries:

Question 1

Under what condition will diffusion take place most rapidly?

• Answer: a. movement from an area of high concentration to an area of low concentration

Question 2

What do you think will happen if no energy is used?

• Answer: a. Some O2 will enter the cell.
• Answer: b. Some CO2 will leave the cell.
  (Note: Depending on the concentration gradients, both a and b could happen, but typically diffusion allows for both gases to exchange.)
