This diagram shows a red blood cell in a beaker that contains a solution with a higher salt concentration than that inside the red blood cell.
What will happen to the red blood cell in this environment?
The size of the red blood cell will remain constant.
The red blood cell will swell at first and then shrink.
The red blood cell will swell from absorbing salt molecules.
The red blood cell will shrink from losing water molecules.
This diagram represents a closed terrarium exposed to sunlight.
What must happen for the carbon cycle to continue in this terrarium?
All organisms must continue to exchange gases.
The snails must double their production of carbon dioxide.
The plant must produce carbon dioxide at a faster rate.
The decomposers must begin to produce oxygen.
A student noticed that the freshwater plant, Elodea, produced bubbles when placed in direct light. What could the student most likely conclude?
Bubbles of carbon dioxide were produced as a result of photosynthesis.
Bubbles of oxygen were produced as a result of photosynthesis.
Bubbles of carbon dioxide were produced as a result of cellular respiration.
Bubbles of oxygen were produced as a result of cellular respiration.
Which statement best explains how sweating during exercise maintains homeostasis?
It regulates mineral concentrations in cells.
It regulates body temperature.
It maintains water balance.
It maintains sugar balance in cells.
A contractile vacuole helps protists eliminate excess liquid. This is a “pumping" process which reduces pressure inside the cell and prevents the cell from bursting. What is most likely the source of energy for this process?
DNA
lipids
ATP
ribosomes
Which word equation best represents the process of cellular respiration?
carbon dioxide + glucose → oxygen + water
carbon dioxide + water → glucose + oxygen
glucose + oxygen → carbon dioxide + water
oxygen + water → carbon dioxide + glucose
How does the body of a runner keep up with the demand for energy when cellular oxygen levels are low?
through energy production in the mitochondria
through aerobic respiration in the plasma membrane
through ATP produced directly from sunlight
through anaerobic respiration in the cytoplasm
During strenuous exercise, body temperature increases. The body responds to the increase in temperature by sweating, which helps to reduce the body temperature. Which is demonstrated in this situation?
excretion
metabolism
homeostasis
synthesis
What is the function of autotrophs in the carbon cycle?
to use oxygen to produce glucose
to take in excess water
to use carbon dioxide to produce glucose
to feed on herbivores
How does the amount of energy resulting from fermentation compare with that of aerobic respiration?
Aerobic respiration results in less energy.
Aerobic respiration results in more energy.
Each process results in equal amounts of energy.
Each process results in variable amounts of energy.
A freshwater plant is placed in a container of saltwater. What will most likely happen to the cells of the plant?
They will swell because water will move into them.
They will swell because salt will move into them.
They will shrink because water will move out of them.
They will shrink because salt will move out of them.
If energy is needed to move materials into or out of a cell, what is most likely occurring?
active transport
passive transport
osmosis
diffusion
Which statement best compares aerobic and anaerobic respiration?
Less ATP is generated during anaerobic respiration than during aerobic respiration.
More water is generated during anaerobic respiration than during aerobic respiration.
More oxygen is generated during anaerobic respiration than during aerobic respiration.
Less lactic acid is generated during anaerobic respiration than during aerobic respiration.
Which would be the best evidence that a cell is using active transport to move a substance across its cell membrane?
Substances are moving rapidly across the cell membrane.
ATP is being rapidly consumed near the cellular membrane.
Substances are moving from high to low concentrations.
Substances are moving through channels in the cell membrane.
