Summary Introduction
To discuss:
How the energy investment by a female frog and female human lead to reproductive success.
Concept introduction:
Frogs and humans apply the same reproductive strategy called iteroparity. Iteroparity is where the organism reproduces multiple times over its life span.

QUESTION:
During the winter, many species of amphibians and reptiles go into a hibernation-like state called overwintering. They eat little or no food, slow their metabolism and breathing rate dramatically, and most of their bodily functions shut down. Interestingly, many of these species choose to spend the winter underwater. Why might it be advantageous to overwinter at the bottom of a pond rather than on land? EXPLAIN.
How do different types of energy investment by females contribute to the reproductive success of a frog, a chicken, and
human?

- 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.
