Iti do a cohort study on some new cute animal, and I discover that most of the individuals die at a relatively young age, and only a few live close to the maximum age for the species, what
would you predict about the reproductive strategy of this species?
O They probably produce relatively few offspring and invest a lot of parental care into each offspring.
O They probably produce a lot of offspring, and invest a lot of parental care into each one.
O They probably produce a lot of offspring but do not invest much parental care in any individual offspring
O They probably produce offspring only after individuals manage to live to close to their maximum age
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.
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.

- In seahorses, males incubate and care for offspring. Thus, the males are more likely to be tied up in reproduction at any point in time relative to females. Which sex do you predict will be the choosey sex in this species and why? Males -- because fewer are available to mate Males – because male-male competition is incredibly strong Females – because sperm are cheap to produce Female – because the operational sex ratio is biased in their favor The sperm of chimpanzees have faster swimming speeds than those of gorillas. Based on what you know about sperm competition, what would you predict about differences between these two species in female re-mating frequency and sperm viability? In chimps, females mate only once and sperm are viable for only a day In chimps, females mate multiply and sperm live for a long time In chimps, females mate only one, and sperm live for a long time In chimps, females mate multiply, and sperm live for only a day Which of the following sexual traits is…arrow_forward| bartleby Male red-winged blackbirds have bright red patches on their shoulders (epaulets).

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.
