source A prolactin B insulin C aldosterone D melatonin E calcitonin F epinephrine 11 10 adrenal cortex 10 C MULTIPLE CHOICE Choose the one alternative that best completes the statement or answers the question 11 When stimulated by a particular hormone there is a marked increase in the activity of G proteins in the membrane The hormone is probably A a peptide B testosterone C aldosterone D estrogen E a steroid 12 Synergism occurs when A hormones working together produce a larger effect than predicted B hormones working together produce a smaller effect than predicted C one hormone inhibits the release of a second hormone D one hormone triggers the secretion of a second hormone E a hormone can exert its full effects only in the presence of another hormone 13 Hormones acting through signal transduction pathways elicit a response compared to hormones that produce genomic effects A faster B equal 13 C slower 12 15 14 16 D flatworms B segmented worms 14 Simple reflexes in a worm are integrated within a segment rather than in the brain because A worms have a ganglion at each segment B worms do not have a nervous system C worms do not have brains D worms have a neural network
