29.nammals have skins and mucous membranes that are sensitive to secretions like poison oak. These secondary compounds are primarily adaptations that function in which of the following ways? (A)to favor pollination (B) to foster seed dispersal (C) to decrease competition (D) to inhibit herbivory

30.Fungi produce many compounds that humans use medicinally. Which of th statements best describes the evolution of these compounds in fungi? (A)Humans used artificial selection to develop fungi (B)That produced specific compounds. e presence of compounds in the fungi was accidentally produced and has r (C)The compounds probably provide a benefit to the fungi. (D) The compounds are produced as a result of sexual reproduction and recombination.

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

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

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.

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
