A student is investigating how substrate concentration affects the rate of an enzyme-catalyzed reaction. Which THREE variables should be kept constant in the setup of the student’s investigation?

• temperature of the reaction

• amount of enzyme

• amount of substrate

• amount of product

• pH of the reaction

Tupai is part of the Leeward Islands. For years, people were not allowed on this island. Recently, it has been opened to tourists. How will increased development and human interactions likely affect succession on this island?

• Lichens will increase quickly, creating a climax community.

• Mature trees will decrease, creating a pioneer community.

• Biodiversity will decrease as the number of species decreases.

• More diverse species will move into the area as biodiversity increases.

Which claim about reproduction in dogs can best be supported using a valid argument?

• Offspring produced by sexual reproduction are genetically identical.

• Gametes from both dogs are needed to maintain the correct number of chromosomes in the offspring.

• Phenotypic variation will occur in the offspring as a result of mitosis in the gametes.

• Binary fission is required for sexual and asexual reproduction in dogs.

Based on the diagram, which statement best explain how the green sea slug is able to produce its own food?

• the slug is able to convert the oxygen needed for cellular respiration into glucose in the chloroplasts

• the slug is able to store algae within its body and use the glucose produced by the algae for cellular respiration

• the slug is able to use the chloroplasts to make glucose molecules that it then uses for cellular respiration

• the slug is able to perform cellular respiration to provide the carbon dioxide needed for photosynthesis
