What do viruses have in common with living cells? They both...

use glucose for cellular respiration

What is the capsid of a virus?

the receptors to which it binds

Viruses can be transmitted through air, water, food, insect bites, and direct skin contact. Once a virus gains entry to the body, it invades a host cell in order to -

access cellular process for replication

deactivate the host cell's defenses

synthesize antibodies for defense

metabolize host proteins and grow

Some students used vinegar to dissolve away the shells of three eggs and used the eggs as models of human red blood cells . The students observed the changes in the eggs when they were placed in different solutions . (View Image) Which statement best describes the role of the cell membrane in this model?

The cell membrane allows water to enter and leave the cell.

The cell membrane is an impermeable barrier that prevents water from entering the cell.

The cell membrane allows solutes to enter the cell, which causes the cell to shrink.

The cell membrane removes solutes from the environment.

Which of these correctly identifies the two cells described in the table?

Cell 1 is Prokaryotic, Cell 2 is Eukaryotic

Cell 1 is Eukaryotic, Cell 2 is Prokaryotic

Both cell 1 and cell 2 are Eukaryotic

Both cell 1 and cell 2 are Prokaryotic

The cellular process known as the sodium-potassium pump was discovered in the 1950's by Jens Christian Skou, a Danish Scientist. This process is a form of active transport that moves three sodium ions to the outside of the cell for every two potassium ions that it moves into the cell. Which of these best explains why energy is needed for active transport?

Ions are moved against the concentration gradient

Ions are attached to large proteins

Ions are trapped inside the plasma membrane

The diagram illustrates the activity of vesicles during a cellular process. Which statement best explains the function of the vesicles?

Transporting packaged molecules from the Golgi apparatus to be released out of the cell

Delivering packaged materials to the golgi apparatus for protein synthesis.

Exchanging genetic information between the Golgi apparatuses of separate cells.

Extracting portions of the Golgi apparatus to be represented for growth within the cell

The diagram shows cellular activity across a cell membrane. Which two process does this diagram most directly model?

Homeostasis and transport of molecules

Energy conversions and the synthesis of new molecules

Synthesis of new molecules and homeostasis

Transport of molecules and energy conversions

The human immunodeficiency virus (HIV) often infects and destroys CD4 T cells. These CD4 T cells are one of many kinds of white blood cells that are an important part of the immune system. The most common danger related to the destruction of CD4 T cells is _

an increase in the threat of diseases caused by microorganisms and viruses

an increase in the risk of high blood pressure

a decrease in the flow of blood to vital organs

a decrease in the amount of oxygen being transported to tissues

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?

The glycoprotein structures are used for attachment, and the cilia are used to move fluids surrounding the cell.

The glycoprotein structures are used to obtain nutrition, and the cilia are used to secrete proteins.

The glycoprotein structures are used to provide physical support for the viral envelope, and the cilia strengthen the cell membrane.

The glycoprotein structures are used for defense, and the cilia for locomotion.

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 above. 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?

The H1N1 virus replicates quickly.

The H1N1 virus is dormant in cells.

The H1N1 virus does not mutate.

The H1N1 virus is transmitted through a vector host, such as a mosquito.

Which of the following describes how viruses and cells are similar?

They both have the ability to reproduce

They both use and obtain energy

At the end of the lytic cycle (the cycle that makes viruses)...

The host cell is destroyed (lysis)

The host cell continues to function normally

The host cell divides into two new cells

Why do viruses have projections on the outside?

To send signals to other viruses.

Which of the following correctly describes viruses?

non-living because they cannot reproduce on their own

non-living because they grow and develop

living because they can use energy

living because they can maintain homeostasis
