13. A child falls off his bicycle and skins his knee. Which of the following processes is not involved in the formation of the blood clot that seals the wound? Clotting factors are activated by platelets Activation of thrombin * Cleavage of fibrinogen into fibrin threads by prothrombin Formation of fibrin clot Platelets stick to exposed collagen fibers at wound site 14. In a cross section through an artery and vein running parallel in your leg, the vessel would necessarily be the artery. with the largest interior diameter with more muscle tissue and elastin in the wall lined with endothelium with valves to prevent backflow All of the above 15. Which of the following statements about CO2 is false? CO2 is less soluble in water than is Oz- The amount of CO2 in the atmosphere is extremely small. Pco2 is higher in stagnant water than in fast-flowing water. For air-breathing animals, co2 readily diffuses from the body to the environment at sea level and at high altitude. Aquatic ectotherms typically do not face challenges in Co2 exchange
