Responding variable
Manipulated variable
Dependent variable

According to the claim about hydrogen peroxide and catalase, what happens to the reaction rate as the amount of hydrogen peroxide increases?
The reaction rate decreases steadily.
The reaction rate increases at first and then levels off.
The reaction rate remains constant.
The reaction rate decreases and then increases.
What does the graph suggest about enzyme activity when there is far more substrate than the enzyme can deal with?
The enzyme works faster and faster.
The enzyme stops working completely.
The enzyme becomes saturated (full) and the reaction rate levels off.
The enzyme breaks down all the substrate instantly.
Why does the reaction rate level off when the concentration of substrate is very high, according to the evidence provided?
The enzyme is destroyed by the substrate.
The enzyme is saturated (full) and cannot process more substrate at once.
The substrate turns into a different chemical.
The temperature decreases.
Which process describes the diffusion of water across a selectively permeable membrane from high to low concentrations?
Osmosis
Simple diffusion
Facilitated diffusion
Active transport
What is the term for a cell structure that has its own membrane and houses genetic information, acting as the control center of the cell?
Nucleus
Nucleoid
Mitochondria
Ribosome
Which cell structure is not enclosed by a membrane but houses genetic material?
Nucleoid
Nucleus
Chloroplast
Endoplasmic reticulum
What is the process called when molecules move from high to low concentrations through transport proteins in the cell membrane?
Facilitated diffusion
Simple diffusion
Osmosis
Active transport
What is the term for molecules moving through the cell membrane from high to low concentration until equilibrium is reached?
Simple diffusion
Osmosis
Facilitated diffusion
Endocytosis
How does increasing the amount of salt in a solution affect the percent change in mass of plant cells, according to the claim provided?
The percent change in mass decreases
The percent change in mass increases
The percent change in mass stays the same
The percent change in mass fluctuates randomly
Why does the percent change in mass of plant cells decrease when the concentration of salt outside the cell increases?
Water moves out of the cell due to osmosis
Water moves into the cell due to osmosis
Salt moves into the cell by active transport
The cell produces more water internally
What is the independent variable tested in the experiment shown in the graph "Percent Change in Mass vs. Salt Concentration in Celery"?

Which organ captures oxygen from the water and releases carbon dioxide in fish and crayfish?
Pyloric Caeca
Lateral Line
Gills
Organ
What is the correct term for a group of tissues working together?
Organ

Pyloric Caeca
Which of the following is a possible claim about the effect of light on photosynthesis in algae?
If we increase the amount of light, then the final pH will increase because the more light available, the more the algae will use up carbon dioxide to complete photosynthesis.
If we decrease the amount of light, then the final pH will increase because algae need less carbon dioxide.
If we increase the amount of light, then the final pH will decrease because algae will stop photosynthesis.
If we keep the light constant, the final pH will always decrease.
Which of the following best describes how pH is used to study photosynthesis?
An increase in pH means photosynthesis is increasing.
A decrease in pH means photosynthesis is increasing.
Which of the following best describes how pH is used to study cellular respiration?
An increase in pH means cellular respiration is increasing.
A decrease in pH means cellular respiration is increasing.
Which process is described as the number of chromosomes per cell being cut in half through the separation of homologous chromosomes?
Mitosis
Crossing Over
Meiosis
Regulation
What is the function of specialized proteins called regulators in the cell cycle?
They exchange portions of chromatids during meiosis.
They facilitate the progression from one phase of the cell cycle to the next.
They cut the number of chromosomes in half.
They divide the cell nucleus.
What is the process in which the cell nucleus divides called?
Meiosis
Crossing Over
Mitosis
Regulation
During which process do homologous chromosomes exchange portions of their chromatids?
Mitosis
Crossing Over
Regulation
Cytokinesis
