Which other molecule is a product of this process?

When mammals get an infection, their internal body temperature often rises 2 to 3 degrees Celsius. The body gets the energy it needs to react to an infection by-

increasing the rate of cellular division

decreasing the rate of glucose movement into the cell

increasing the rate of cellular respiration in mitochondria

decreasing the rate at which carbon dioxide is removed from the cell

What conditions cause the contractile vacuole to fill with water?

the concentration of water is greater outside the cell than inside the cell

the temperature of water in the vacuole is higher than the temperature of its environment

the concentration of water inside the cell is the same as the concentration outside the cell

the temperature of water in the vacuole is lower than the temperature of its environment

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-

deactivate the host cell's defenses

synthesize antibodies for defense

metabolize host proteins and grow

access cellular processes for replication

Which statement is best supported by the observable structures of the different humerus bones?

The primate lived in similar environments

The primates shared a common ancestor

The primates interbreed with similar organisms in a population

The primates had diets that consisted of similar types of food

After examining the fossil record, scientists have determined that scorpions today are much smaller than their extinct ancestors. For example, Jaekelopterus rhenaniae, a giant scorpion species that lived 255 million to 460 million years ago, was 2.5 meters long. Which of the following conclusions is supported by this information?

Scorpions living today have increased their numbers since they first appeared.

Scorpions in the fossil record are smaller than their descendants are.

Scorpions have changed as a result of natural selection.

Scorpions do not appear in their original state in the fossil record.

Which result is most likely to occur to the beetle population due to predation over time?

The number of light colored beetles in the population will increase

There will be more dark colored beetles than light colored beetles

The number of light colored beetles will decrease

The dark colored beetles will move to a different type of tree

Which statement about the beetles in this environment is best supported by the data?

Green beetles are more fit for the environment than brown beetles are.

Brown beetles undergo a greater number of unfavorable mutations than green beetles do.

Green beetles have a greater gene frequency among their population than brown beetles have.

Brown beetles have a shorter life cycle than green beetles have.
