- Many 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. [Select] [Select] protogynous hermaphrodite continuous hermaphrodite protoandrous hermaphroditeSexual reproduction in unpredictable environments provide immediate benefits to individuals including the following except -- A. There are more opportunites for offspring to specialize in different niches in an environment. B.

- The pesticide DDT was widely used in the 1940s as a method of insect control. In the late 1950s the first DDT-resistant mosquitoes were discovered, and eventually DDT-resistant mosquitoes were found globally. When DDT is used now, the development of DDT resistance in mosquito populations occurs in months rather than years.Which of the following best explains the observations concerning DDT resistance in mosquitoes? * nd 2 school The proportion of DDT-resistant mosquitoes in a population remains constant due to the metabolic costs of DDT utilization DDT is a chemical signal that delays normal reproductive cycles in many mosquito populations. Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT. A population of 1.492 finches is introduced to a rainforest. Over the next year, the finches showa death rate of…Answer the following thoroughly and add comments as to how this topic affects humanity (and you) and give examples. a) Discuss reproductive strategies and sexual selectionWhatis not included in the defining characteristics of eusociality?a.Reproductive and non-reproductive castesb.Intrasexual selection of matesc.Multi-generational cohabitationd.Cooperative care of younge.All are defining characteristics
