35. A plant developed a mineral deficiency after being treated with a fungicide. What is the most probable cause of the deficiency?
(A) Mineral receptor proteins in the plant membrane were not functioning.
(B) The genes for the synthesis of transport proteins were destroyed.
(C) Active transport of minerals was inhibited.
(D) Mycorrhizal fungi were killed.

31. Which of the following is an advantage of using molecular data rather than morphological data for phylogenetic analysis? (A)Molecular data can be gathered in the lab, while morphological data must be gathere (B) Molecular data is based on genetic relationships rather than morphological similarities. (C) Morphological changes usually do not result from molecular changes. (D) Some phyla vary too widely in morphological characteristics to be classified accurately.

32. Our understanding of many of the evolutionary relationships among animals changed after those phylogenies were based on morphological and molecular data (as opposed to only using morphological data). What do these changes indicate? (A)molecular and morphological studies rarely agree (B) molecular studies add additional information to morphological studies and improve our understanding of evolutionary history (C) molecular studies are less reliable than morphological studies (D) molecular studies are extremely time consuming and expensive and really don't add additional information to our understanding of evolutionary history

33. Primate evolution and behavior, such as hunting skills, have been directed in part by the developm ent of depth perception. What anatomical change made depth perception possible? (A)a smaller brain (B)the development of compound eyes (C)location of the eyes at the front of the head (D)diurnal activity

34. The biological molecule specific to woody sclerenchyma cells is (A)cellulose (B) starch (C) lignin (D) chlorophyll

36. Which answer best describes how roots acidify the soil solution? (A) Roots release CO2 and pump K+ into the soil. (B) Roots release CO2 and pump H+ into the soil. (C) Roots release NaCl and pump Nat into the soil. (D) Roots release NaCl and pump Cl- into the soil.

37. The part of a flower that can develop into the pulp of a fleshy fruit is______. (A) stigma (B) style (C) ovule (D) ovary

38. The primary sites of auxin (IAA) production in plants are______. (A) shoot apical meristem and young leaves (B) roots (C)seeds (D) ripening fruits

39. The hypothalamus in the brain releases the hormone corticotropin-releasing hormone (CRH) that triggers the release of adrenocorticotropic hormone (ACTH) from the pituitary gland. ACTH travels through the blood to cause the release of cortisol from the cortex of the adrenal glands. If cortisol acts with negative feedback on CRH and ACTH, what would you expect to happen when cortisol is released? (A) CRH and ACTH levels will decrease (B) CRH levels will increase, but ACTH levels will decrease (C) CRH levels will decrease, but ACTH levels will increase (D) CRH and ACTH levels will increase

40. The chemical structure of prostaglandins is derived from______. (A) oligosaccharides (B) fatty acids (C)steroids (D) amino acids

41. It is important for pregnant women to consume folic acid supplements because______.  (A) the fetus is not able to acquire oxygen by breathing on its own (B) the fetus stores folic acid in high quantities (C)folic acid deprivation is associated with neural tube defects in a fetus (D) folic acid deprivation is a cause of heart abnormalities in a newborn
