Each Each Each Each Each

species species species species species

lives in a slightly different habitiat. functions at a different trophic level. makes up a different population. occupies a different niche. inhabits a different biome.

12 The flow of which of the following into the mitochondrial matrix provides the chemiosmotic energy for the synthesis of ATP? A B C D E

ADP Glucose Protons Inorganic phosphate Electrons

13 Which of the following is TRUE of C4 plants such a corn? A B C D E

The stomates open at night rather than during the day. The plants are classified as cacti. The Calvin cycle is confined to the bundle sheath cells. The will not grow in climates where the temperature exceeds 70 degrees Farenheit. The have an anatomy that is found only in gymnosperms.

Fall Final Review 15 Which of the following best summarizes the relationship between dehydration reactions and hydrolysis? A B C D E

Dehydration reactions assemble polymers, and hydrolysis breaks down polymers. Hydrolysis only occurs in the urinary system, and dehydration reactions only occur in the digestive tract. Dehydration reactions can only occur after hydrolysis. Hydrolysis creates monomers, and dehydration reactions break down polymers. A and C are correct.

16 What is the term used for a protein molecules that assists in the proper folding of other proteins? A B C D E

denaturing protein renaturing protein enzyme protein Chaperonin tertiary protein

17 All of the following statements concerning characteristics of predator-prey relationships are correct EXCEPT: A B C D E

A rise in the population of prey is often followed by a rise in the population of predators. A rise in the population of predators is followed by a decrease in the population of prey. Camouflage is an adaptation that protects prey. The population of predators most often eliminates the population of prey. The production of large numbers of offspring within short periods ensures the survival of some prey populations.
