the activity of carbonic anhydrase d Both B and C are true X e All of these are true 8 Why do we inhale oxygen and exhale carbon dioxide d Exhaled carbon dioxide removes oxygen carrying spent electrons from the body X e Only B and C are true a Inhaled oxygen is used as a carrier to remove carbon from the body Inhaled oxygen is used as a carrier to remove spent electrons from the body Exhaled carbon dioxide is the product of the breakdown of glucose during cell respiration 9 Polysaccharides fats and proteins are all formed by X a dehydration synthesis b ionic bonding c hydrogen bonding d disulfide bridges e hydrolysis 10 Which of the following types of animal tissues is most diverse in structure a muscle b nervous c epithelial X d connective e glia 11 Which of the following defensive mechanisms is common to plants but not animals a receptor ligand binding d systemic responses b production of defensive proteins that alert uninfected cells e all of these are shared by plant and animal defensive systems X c cell death to wall off a pathogen and prevent its spread 12 How would a cell lacking the epinephrine receptor respond to epinephrine a The specific response would depend on the intracellular signaling pathways present in the cell X b It would not respond at all to epinephrine c It would slowly increase the rate of cellular respiration d It would decrease the rate of cellular respiration e It would very rapidly increase the rate of cellular respiration Page 3 PINK 13 A stalk of broccoli is comprised of fiber primarily a carbohydrate known as which is built from carbon brought into the plant as a chitin bicarbonate X d cellulose carbon dioxide b glycogen carbon dioxide e starch bicarbonate c cellulose bicarbonate 14 Which molecule or type of molecule is most abundant in the typical living cell d carbohydrate X e water a protein b hydrocarbon c lipid a pathogens b insect predators c other plants 15 Plants have evolved defenses against all of the following EXCEPT d mammalian predators X e Plants have evolved defenses against all of these 16 An unfortunate interaction with a wild boar has left Vigo with a deep laceration that is losing a considerable amount of blood Which of the following structures will be involved in maintaining his blood pressure and ensuring his survival a hypothalamus b pituitary c adrenal glands d kidney X e all of these 17 The human immune system is comprised of levels of activity The phase of the cell cycle with the LEASTmass of DNA is d four e None of these d Anaphase e Prophase a one b two X c three 18 X a G1 b S c G2 19 Which of the following is a function that the circulatory system the lymphatic system and the digestive system all share a Maintain homeostasis b Maintain proper nutrient and metabolite levels c Maintain proper fluid levels X d Both A and B e All of the above 20 Fluid always moves from to within the of a plant a Chloroplast mitochondria parenchyma b Source sink vacuole X c Source sink phloem d Leaves roots phloem e Both C and D are correct answers PINK Page 4 21 Most of the ATP produced during respiration is the result of the reactions that take place during which of the following a Glycolysis b Lactic acid fermentation c Alcoholic fermentation d Acetyl CoA formation X e Citric acid cycle 22 Which of the following most correctly compares and contrasts hormones and neurotransmitters X d While both act as chemical signals between cells hormones travel through the bloodstream and neurotransmitters travel across synapses e None of the above properly describes both chemicals a b c While both are chemicals that serve to send signals between cells hormones move only through ducts while neurotransmitters act only through synapses While both are chemicals the reach target cells through the bloodstream hormone signals are secreted while neurotransmitter signals are amplified While both are chemicals secreted by glands neurotransmitters act on neurons and hormones act on non specific target cells 23 An atom must contain which of the following components i Proton ii Isotope iii Neutron iv Electron v Ion a i iii v b ii iii iv c i iii iv X d i iv e i iii 24 The process of allows plants to intake minerals bound to clay particles a translocation b capillary exchange X c cation exchange d capillary exchange e girdling 25 In order to produce antibodies and memory cells a B cell requires a an antigen presented by a Helper T cell d Both A and B X e Both A and C b Interleukin 1 c Interleukin 2 26 During
