While Jack and Eliza were backpacking on a trail in YellowstonePark, they encountered a grizzly bear cub that seemed amazinglytame. However, while Jack tried to feed the cub, its mother appearedand attacked him. Eliza escaped by climbing a tree, but Jack receivedseveral deep lacerations (cuts) and lost a lot of blood over the nextseveral hours. Eliza helped him reach medical aid, and he survived.Which of the following mechanisms was (were) activated to help keepJack alive? Explain your choice.(1) baroreceptor mechanism(2) CNS ischemic response(3) renin-angiotensin-aldosterone mechanism(4) fluid shift mechanism(5) antidiuretic hormone mechanism(6) adrenal medullary responsea. 1,2,3,4,5,6 b. 1,3,4,5,6 c. 1,6 d. 1,4,6 e. 1
