Karlee and Benjamin are studying how cells provide energy to maintain homeostasis. Based on this model, which statement best explains how this cellular process provides the energy an organism needs?

• Glucose molecules are metabolized, resulting in the storage of energy.

• The bonds in glucose molecules are broken down, resulting in the loss of energy.

• Glucose molecules are broken down, resulting in the release of energy that is captured in ATP.

• The bonds of complex molecules are metabolized to form glucose, resulting in the formation of ATP.

Karlee and Benjamin are studying a population of wild rabbits in a forest. Select two statements that support their claim that increased genetic diversity within the rabbit population increases the chances of the survival of the species.

• The rabbits would be better able to resist diseases.

• The rabbits would be better able to adapt to changes in climate.

• The rabbits would be better able to mate more frequently.

• The rabbits would be better able to produce individuals with similar genotypes.

• The rabbits would be better able to produce large numbers of offspring.

In pea plants, round pods (R) are dominant to wrinkled pods (r) and yellow pods (Y) are dominant to green pods (y). The Punnett square below shows the possible gene combinations for a dihybrid cross between two parent plants that are heterozygous (RrYy).

• 3/16

• round and green offspring

• 9/16

• Round and yellow offspring

• 1/16

• wrinkled and yellow offspring

• 3/16

Karlee and Benjamin are studying pea plants in their biology class. They learn that round pods (R) are dominant to wrinkled pods (r) and yellow pods (Y) are dominant to green pods (y). The Punnett square below shows the possible gene combinations for a dihybrid cross between two parent plants that are heterozygous (RrYy). What is the probability of producing round and green offspring?

• 3/16

• 1/16

• 9/16

• 6/16
