A student is conducting an investigation to determine the effect of temperature on the metabolism of yeast (Saccharomyces cerevisiae). Yeast and sugar are added to water, the gas produced is captured, and its volume is recorded. Which variables should be held constant during this investigation?

What is the mass of yeast and mass of sugar?

100

What best describes a characteristic that distinguishes Fungi from other kingdoms?

What is fungi are multicellular and break down dead plant and animal matter?

100

In what circumstance would it be most likely for large organic molecules to form during a laboratory experiment?

What is if RNA segments that could act as catalysts formed?

100

What is a characteristic that defines a cell as a eukaryote?

What is having a nucleus?

100

What best summarizes why the technological invention of microscopes was important to biology?

What is it allowed for development of the cell theory?

200

To help patients replenish body fluids during an illness, doctors need to understand how cells behave in their environment. Doctors have confidence in what they know about how cells behave because of this.

What is the cell theory, that has been tested, refined, and observed to be true over hundreds of years?

200

If a plant's leaves developed so that its vascular tissue only contained xylem, how would this affect the rest of the plant's physiological processes?

What is the glucose produced during photosynthesis in the leaf cells would not be able to reach the rest of the plant, and the cellular respiration in the plant's other cells would not function?

200

What best compares the structures of lipids and carbohydrates?

What is both consist of carbon, hydrogen, and oxygen, but carbohydrates have repeating structural units and lipids do not?

200

What best compares a eukaryote and a prokaryote?

What is eukaryotes have membrane-bound organelles, while prokaryotes have few specialized structures?

200

What provides the best argument for separating Archaea from Bacteria into their own domains instead of leaving them together in the single kingdom, Monera?

What is it was discovered that they make their membranes differently and copy their DNA differently?

300

Scientific law and a scientific theory are similar in that both do this.

What is represent a large amount of scientific investigation and evidence?

300

Terrestrial plants have a waxy covering produced by the dermal tissue called the cuticle. If this waxy covering was overproduced so that the stomata became clogged, what would happen to the plant?

What is the plant would not be able to exchange oxygen for carbon dioxide, and the plant's ability to perform photosynthesis would be limited?

300

Some proteins catalyze biochemical reactions. If a genetic defect prevented a protein catalyst from being produced, what do you predict would happen in the cell?

What is the reaction the protein catalyzes would proceed very slowly or not at all?

300

What best compares the structures found in plant cells and animal cells?

What is animal cells do not contain chloroplasts, cell walls, or a large central vacuole while plant cells do?

300

What part of the brain is the last to develop?

What is the frontal lobe of the cerebrum?

400

If a company claims that its product has been proven scientifically, which of the following should have taken place if the results are to be considered reliable?

What is results should have been peer reviewed and repeated producing the same findings?

400

How are fungus-like protists similar to heterotrophic protists?

What is they both need to gather food from their environment?

400

A variety of organic molecules have been found in meteorites that have landed on Earth, including individual amino acids and lipid molecules. To date, however, no microspheres have been found on these meteorites. Why is it unlikely that microspheres will ever be found on a meteorite even though lipids can form in them?

What is groups of lipids will only form into microspheres when they are in liquid water?

400

In the cytosol of a cell, lactic acid is being formed from pyruvate. What is the most likely conclusion on can make regarding the processes that are occurring?

What is fermentation is taking place as a result of a lack of oxygen?

400

A large piece of plaque breaks away from the inner wall of the carotid artery in an otherwise healthy person. What part of the body would this dislodged plaque most likely affect and how?

What is a narrow vein in the brain would become blocked, restricting blood flow to capillaries in the brain?

500

The graph above shows atmospheric carbon dioxide levels since the year 1880. What conclusion can be drawn from this graph?

What is atmospheric carbon dioxide levels have been rising at an increasingly higher rate as the last century progressed?

500

What correctly compares the two divisions of the plant kingdom?

What is nonvascular plants lack xylem and phloem and reproduce asexually, while angiosperms have xylem and phloem and reproduce sexually?

500

What best describes a result of the polar nature of water molecules?

What is ionic compounds dissolve easily in water?

500

What best explains why meiosis results in greater genetic diversity than mitosis?

What is during meiosis, chromosomes assort themselves independently of each other, which allows more different possible combinations of chromosomes?

500

What best compares the processes involved in aerobic and anaerobic respiration?

What is glycolysis takes place in the cytosol, while the Krebs cycle and electron transport chain take place in the mitochondria?
