- Egg laying in fruit flies can be triggered (induced) when males transfer their sperm to females. Which of the following is a selective advantage of induced egg laying for the male flies? Less time and energy is expended by the male. The males do not have to produce as much sperm. More eggs can be fertilized. A male fly's sperm is more likely to be used for fertilization.

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.

- Animals attract mates through a variety of behaviors. Diurnal animals tend to rely on visual cues, while nocturnal ones make frequent use of pheromones. In recent years, environmental pollutants called endocrine disruptors are on the rise. Such chemicals mimic hormones in higher-order animals and interfere with the reproductive cycle. Which animal’s reproduction would be most seriously affected in the presence of endocrine disruptors? rats bees fireflies fiddler crabsarrow_forwarddescribe (short stature homeoboxarrow_forwardMany factors influence a species mode of reproduction. Use the descriptions of the following species to predict what system of hermaphroditism they probably display. 1. Individuals rarely disperse once they are sexually mature, and the largest males get the most matings. Females protect the eggs. [Select] 2. Resources are of uniform quality and evenly dispersed, so males are unable to monopolize them. Females are larger than males; Males protect the eggs. [Select] 3. Individuals are solitary, rarely meet others, and have no way of knowing the sex ratio in the population. There is no parental care.

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.arrow_forward
