The arrows show the movement of sugar through a cell membrane. Which cell is using energy to transport sugar?
The cell on the left is using energy to transport sugar.
The cell on the right is using energy to transport sugar.
Both cells are using energy to transport sugar.
Neither cell is using energy to transport sugar.
The arrows show the movement of sugar through a cell membrane. Which cell is not using energy to transport sugar?
The cell on the left is not using energy to transport sugar.
The cell on the right is not using energy to transport sugar.
Both cells are not using energy to transport sugar.
Neither cell is transporting sugar without the use of energy.

With the concentration gradient.
Against the concentration gradient.
What kind of cell transport is happening to maintain homeostasis (balance) in these cells?
The movement of water by osmosis.
The movement of solutes by diffusion.
The cell takes in molecules by endocytosis.
The cell removes molecules by exocytosis.
How does a virus cause a person to develop the common cold?
invades the host cell to reproduce
removes energy from the host cell
produces toxins in the host cell
protects the host cell from bacteria
What do viruses need to reproduce?
they need genetic material
They need a host cell
They need bacteria
They need insulin
Which viral life cycle kills its host cell by lysing (exploding)?
lytic
mitosis
lysogenic
S phase
Which viral life cycle allows viral genetic material to lay dormant while the host cell reproduces?
lytic
mitosis
lysogenic
S phase
How do vaccines work against viruses?
Vaccines are like antibiotics, except they work against viruses.
Vaccines prepare the immune system to fight the virus without harming the host.
Vaccines make it impossible for a virus to enter a host cell.
Vaccines find viral DNA or RNA and cut it to pieces, making the virus unable to replicate.
How does Human Immunodeficiency Virus (HIV) replicate?
Lytic Cycle
Lysogenic Cycle
Mitosis
Binary fission
How does influenza (flu virus) replicate?
Lytic Cycle
Lysogenic Cycle
Mitosis
Binary fission
Should a doctor give a patient antibiotics to treat a disease caused by a virus?
Yes, because antibiotics will stop the cellular processes of the virus, helping the patient get better faster.
Yes, because antibiotics will kill bacteria in the body, giving the immune system an easier time fighting the virus.
No, because diseases caused by viruses are always deadly, meaning that the patient cannot be saved.
No, because viruses are not cells, and antibiotics target cellular processes.
Which shows the correct complementary base pairing for DNA?
C-A, T-G
A-G, C-T
C-G, U-A
T-A, G-C
What is responsible for holding the two strands of the DNA double helix together?

It took millions of years for giraffes to develop long necks. Slow evolution is called:
Punctuated equilibrium
Survival of the fittest
Gradualism
Selective Breeding
A grizzly bear survives because he is well-adapted to his environment. When he reproduces he passes on those traits to his offspring. this process is called
Natural Selection
Selective Breeding
Random mutations
Variations in a species
Heredity is:
Survival of the fittest
The passing of genetic traits from parent to offspring
Believing in false gods
Unexplained
The male and female black widow spider look very different. However, we know they are the same species because:
They reproduce creating fertile offspring
They reproduce creating infertile offspring
They cannot reproduce
They are not the same species
