a)
Anaerobic cellular respiration
b)
Protein synthesis
c)
Aerobic cellular respiration

3.
Some students used vinegar to dissolve away the shells of three eggs and used these eggs as models of human red blood cells. The students observed the changes in the eggs when they were placed in different solutions.
Which statement best describes the role of the cell membrane in this model?
Which statement best describes the role of the cell membrane in this model?
a)
The cell membrane is an impermeable barrier that prevents water from entering the cell.
b)
The cell membrane allows solutes to enter the cell, which causes the cell to shrink.
c)
The cell membrane allows water to enter and leave the cell.
d)
The cell membrane removes solutes from the environment.

H1N1 flu is a highly contagious viral infection caused by the influenza A (H1N1) virus. The symptoms of H1N1 flu are listed in the box below. An antiviral agent administered within 48 hours of the appearance of symptoms can reduce the severity of the illness.
Why is it important to administer an antiviral agent to an infected person within 48 hours of the appearance of symptoms?
Why is it important to administer an antiviral agent to an infected person within 48 hours of the appearance of symptoms?
a)
The H1N1 virus is dormant in cells.
b)
The H1N1 virus replicates quickly.
c)
The H1N1 virus does not mutate.
d)
The H1N1 virus is transmitted through a vector host, such as a mosquito.

Models of the human immunodeficiency virus (HIV) and an animal cell are shown below.
What is the difference in the function of the glycoprotein structures of an HIV virion and the cilia of an animal cell?
What is the difference in the function of the glycoprotein structures of an HIV virion and the cilia of an animal cell?
a)
The glycoprotein structures are used for attachment, and the cilia are used to move fluids surrounding the cell.
b)
Ughhhhh
c)
The glycoprotein structures are used to provide physical support for the viral envelope, and the cilia strengthen the cell membrane.
d)
The glycoprotein structures are used for defense, and the cilia are used for locomotion.

budding
d)
mitosis
8.

The differences between two molecules include the type of sugar that forms a section of the molecules and the identity of one of the four nitrogenous bases that make up another section of the molecules. These two molecules are -
a)
Proteins
b)
Lipids
c)
Nucleic acids
d)
Complex carbohydrates

Cells typically respond to DNA damage in three ways: by ceasing to grow and divide until the damage is repaired, by permanently ceasing to grow and divide, or by dying. In 2010 a group of scientists reported that a certain kind of immune reaction can cause DNA damage that leads to a fourth response. DNA damage can turn off genes involved in cell-signaling pathways. Turning off these genes can cause less-mature cells to divide too rapidly, often leading to the development of -
a)
Tumors
b)
Allergies
c)
Hemophilia
d)
Cardiovascular disease
