- When and how can long-term coexistence occur?How can altruism be adaptive if it can result in fewer offspring for an individual?Is the following case study an r-strategist or a K-strategist? American toads practice explosive reproduction. During the first warm days in spring, both males and females migrate from forests and converge on ponds. Reproduction is quick, taking only a few days. Females lay hundreds of eggs in jelly-filled sacks along the sides of the pond or stream. As soon as the eggs are laid, males and females abruptly leave the pond. Offspring are left to develop, hatch, and grow on their own, maturing in about three months.
- What are the relative advantages and disadvantages ofsemelparity and iteroparity? In answering, consider iteroparousspecies that have both short and long expected life spans in theirnatural environments.In an iteroparous species lifetime fitness is maximized at investment, while in semelparous species level of reproductive an intermediate maximal effort is exerted in a single reproductive event Maximal an intermediate effort is exerted in one of many reproductive events an intermediate minimal effort is exerted in a single reproductive event maximal an intermediate effort is exerted in a single reproductive event an intermediate maximal effort is exerted in one of many reproductive eventsWhat is kangaroo mother care and what are its benefits?
- What are some reproductive changes that may be adaptive in the face of parasitism? Why may males have higher rates of mortality due to parasites than females?In polygynous species, why do females in good condition invest more energy in male offspring than in female offspring? Females in good condition produce males in good condition but females in poor condition. Male offspring are more likely to produce more grandchildren than female offspring. Male offspring are more likely to help provide for the mother and her future offspring. Male offspring tend to mature earlier than female offspring to produce grandchildren sooner.what are the pros and cons of reproductive technologies? Explain them.
- What is NOT a disadvantage of internal fertilization? the ability to reproduce on land without needing external water the need for more specialized reproductive structures the production of fewer embryos the reduction in the randomness of fertilization (less genetic variability in offspring)How important is the definition of moral community to defining the moral status of gametes and embryos?What do mean by vivipary?
