Question 1 • Which of the following is the best example of K-strategist species? • A- Fruit Flies • B- Fish • C- Humans • D-Beetles • E- Desert Annual Flowers
Question 2 • The role of oxygen in aerobic respiration is • A- The final hydrogen acceptor in the electron transport chain • B- in glycolysis • C- in the Kreb Cycle • D-Exactly the same as a cytochrome • E- To reduce NAD to NAD+
Answer is… • A- the final hydrogen acceptor in the electron transport chain
Question 3 • The frequency of crossing-over event occurring between any two linked genes is • A-Proportional to the distance between them • B- greater if the genes are sex-linked • C- higher if they are dominant and lower if they are recessive • D- higher if the genes are in a male • E- higher if the genes are on separate
Answer is… • A- proportional to the distance between them
Question 4 • What kind of chemical bonds are found between the nitrogenous bases in a molecule of DNA? • A- Covalent • B- van der Waals • C- ionic • D- hydrogen • E- disulfide
Question 5 • Who was the author and naturalist who developed a theory of natural selection independently of Darwin and who is often credited along with Darwin for the theory we accept today? • A- Linnaeus • B- Cuvier • C- Lyell • D- Wallace • E- Lamarck
Question 6 • Genetic Drift has the largest effect on allele frequencies when • A- mating is random • B- the population is small • C- there is no migration, in or out • D- there is no natural selection • E- there is no mutation
Question 8 • Polymerase chain reaction would be carried out to accomplish which one of the following? • A- To prevent a virus from replicating • B- To amplify a region of DNA • C- to identify the location of a point mutation in a genome • D- to identify a chromosome mutation • E- to prepare a specimen of DNA for X-ray diffraction
Question 9 • All of the following structures are adaptations specifically for life on land EXCEPT • A- Xylem • B- roots • C- waxy cuticle • D- seeds • E- cell walls
Question 10 • All of the following are correct about enzyme-catalyzed reactions EXCEPT • A- phosphofructokinase is inhibited by ATP • B- Enzymes speed up reactions by supplying necssary energy • C- enzymes lower the energy of activation • D- enzymes often require the presence of minerals • E- all enzymes are not active at the same pH
Answer is… • B- enzyme speed up reactions by supplying necessary energy
Question 11 • Pinching back a plant, removing the new leaves at the top, results in the plant growing bushier. This happens because when the new leaves are removed, ____________ is removed as well. • A- Gibberellins • B- cytokinins • C- auxins • D- ethylene • E- abscisic acid
Question 12 • All of the following are true about cellular respiration EXCEPT • A- NAD+ is reduced to NADH during both glycolysis and the Kreb Cycle • B- in the absence of NAD+, glycolysis cannot occur • C- ATP is produced by substrate level phosphorylation during electron transport chain • D- the most important product of glycolysis is ATP • E- lactic acid is converted back to pyruvic acid in the liver
Answer is… • D- the most important product of glycolysis is ATP
Question 13 Which is correct about the person from whom this karotype was taken? A- Person has Klinefelter’s syndrome B-Person has sex-linked conditions C- Person has Down’s Syndrome D- Person has hemophilia E- The person has Turner’s syndrome
Question 16 • The population of peppered moths in England changed from white to black in less than 100 years. This is an example of • A- directional selection • B- genetic drift • C- disruptive selection • D- sexual selection • E- artificial selction
Question 17 • The process by which some bacteria convert nitrate to free nitrogen is called • A- ammonification • B- nitrogen fixation • C- denitrifying • D- nitrifying • E- denitrogenation
Question 18 • Which of the following is the dominant stage of the life cycle in moss? • A- Diploid • B- sporphyte • C- flowering stage • D- monoploid (haploid) • E- none of the above is correct
Question 19 • In order to move from the right side of the heart to the left side of the heart, blood must pass through the • A- mitral valve • B- vena cava • C- right atrioventricular valve • D- lungs • E- aorta
Question 20 • A diploid cell has three pairs of homologous chromosomes : AaBbCcDd. How many different gametes can this cell produce? • A- 4 • B- 8 • C- 16 • D- 32 • E- 64
Answer is… • C- 16 • This type of problem can be solved by following this 2 raised to the power of the n umber of pair of alleles. There are four pairs of alleles, so 24 = 16

Answer is… • D- A fertilized egg undergoes a series of changes in the following order cleavage (first division of the zygote), morula (solid ball), blastula (hollow ball), gastrula (formation of three germ layers ), and neurula (formation of nervous system)
Question 23 • Chemical substances released by organisms that elicit a physiological or behavioral response in other members of the same species are known as • A- Auxins • B- hormones • C- phermones • D- enzymes • E- coenzyme
