QUESTION 15 Which of the following statements accurately represents the hormonal control of invertebrate reproduction? • Ecdysone indirectly effects reproduction through its effects on maturation and metamorphosis. Some invertebrates provide substantial parental oversight of juveniles. Invertebrate reproduction is not affected in any way by steroids Invertebrates are both oviparous and viviparous. Metamorphosis has no effect on reproduction. QUESTION 16 Which hormonal agents stimulate an animal to eat by increasing its appetite? • Orexic agents • Anorexic agents • The presence of food in the digestive tract The presence of sugars in the stomach. QUESTION 17 Ecdysone • Binds to a cell surface GPCR leading to guanylate cyclase activation. • Is structurally related to juvenile hormone. • Is not produced from cholesterol. • has a nuclear receptor that heterodimerizes with the USP transcription factor. QUESTION 18 Which of the following accurately describes the differences between vertebrate and invertebrate hormonal regulation of digestion • Invertebrates and vertebrates control digestion and food absorption in very different manners with the same hormones. Secretion and absorption with the GI tract are not hormonally controlled in vertebrates but it is controlled in invertebrates. Just like the hormonal regulation of reproduction, invertebrate hormonal regulation of digestion uses some of the same hormones, unique hormones. Invertebrates hormonally control blood glucose levels without Insulin or Insulin-like peptides. QUESTION 19 Vertebrate hormones regulating digestion • Are mostly steroids. • shares the same effector pathways inside cells. • Are all small peptide hormones. • are commonly found in the CNS controlling different functions unrelated to digestion. QUESTION 20 Why are many more peptide hormones controlling invertebrate than vertebrate reproduction? • Because invertebrate reproduction is complicated by the effects of terpenes. • Because oviparity is common in invertebrates and is rare among vertebrates. • Because invertebrate steroid hormones have no effect on reproduction. Because the physiology underlying reproduction in invertebrates is more varied.
