Step by step
Solved in 2 steps
- 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 hermaphroditeUse the information to answer the following question. Some species of sea stars are able to reproduce both sexually and asexually. Increasing ocean temperatures have impacted the environment of sea stars around the world. Which argument provides the MOST LIKELY explanation for why populations that use sexual reproduction will demonstrate increased survival than those that use asexual reproduction? O A. The population that uses sexual reproduction will have less genetic diversity which will allow them to adapt to the new conditions more quickly. O B. The population that uses sexual reproduction will be able to reproduce at a faster rate and replace the individuals that do not survive new environmental conditions. O C. The population that uses sexual reproduction will reproduce at a slower rate allowing for them to identify and adapt to the new environmental conditions. O D. The population that uses sexual reproduction will have increased genetic diversity which will allow the population…Use the information to answer the following question.

- Which of the following habitat and life history traits would you expect in a species that reproduces sexually, reaches sexual maturity relatively quickly, and provides little parental care? Choose all that apply. A heavy parasite load A predictable environment A low parasite load An unpredictable environment A small number of eggs per reproductive effort A large number of eggs per reproductive effortSalmon live most of their lives at sea, and then return to their natal rivers and streams to reproduce and die. Which type of reproductive strategy does this exemplify? Big-bang reproduction Fast, intensive reproductive investment Slow, gradual reproductive investmentIs 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.
- Match the type of organisms with the appropriate type of offspring production. Birds v [ Choose ] Viviparity Ovoviviparity Oviparity Some sharks Gorillas [ Choose ] Most if not all frogs [ Choose ] Mice [ Choose ]What type of reproductive strategy is used by frogs that lay hundreds or thousands of eggs at a time? K-strategy R-strategy J-strategy X-strategyMockingbirds typically lay 3 eggs. If the mockingbird produces more than three eggs their young are often malnourished because they have so many to feed. If less than 3 eggs are produced they may not have any viable offspring. This is an example of
- Define the term ‘biological success’. Using labelled diagrams where appropriate, explain clearly why insects can be considered to be a biologically successful group. (400- maximum word limit)A trade-off for having many offspring would be that they would require a large amount of parental care. that they would likely be small in size. that they would have high survivorship. that they would likely be large in size.According to Grimes model, which characteristics (life history traits) apply to individuals in the "Competitive" strategy? Question 10 options: The offspring have a high survival rate All of these They produce relatively few offspring They are very mobile They invest very little in their offspring They have an older age of maturity
