- Which of the following statements best describes the advantage of sexual reproduction in organisms? It reduces genetic variation, which may be useful in the future. It prevents adaptation in a changing environment. It yields offspring with novel combinations of traits. It eliminates the possibility of harmful traits being passed on. tnf: Which of the following statements best describes the functions of villi and microvilli? Villi and microvilli form the inner layer of epithelial tissue in the small intestine and increase the absorption of nutrients from chyme. Villi and microvilli absorb food through the small intestine via smooth muscle contractions called peristalsis. Villi and microvilli increase the surface area of the small intestine, which increases the absorption of nutrients by diffusion. Villi and microvilli increase the surface area of the small intestine, which aids in the absorption of bile salts and vitamin B12.In some cases, males or females do care for young of their own species that are not their own, as when certain male fish take over and protect egg masses being brooded by other males or when female ducks acquire ducklings that have just left someone else’s nest. Propose alternative hypotheses to explain this phenomenon. Under what circumstances might adoptions actually raise the caregiver’s reproductive success? Under what other circumstances might adopters help nongenetic offspring as a cost of achieving some other goal? Don't write from any online source..Assume that a scorpion presents a meal to a partner to entice them to mate. This would be an example of which of the following? Delayed Benefits Indirect Benefits Intrasexual selection Direct benefits
- The northern red-legged frog, or Rana aurora, is found along the western coast from British Columbia to Northern California. Their typical breeding season lasts from January to March. The foothill yellow-legged frog, or Rana boylii, is found along the western coast from northern Oregon to central California. Their typical breeding season lasts from April to July. What mechanism might keep Rana aurora and Rana boylii from mating? anatomical isolation temporal isolation geographic isolation behavioral isolationAssume you are studying a species of slug where the eggs are fertilized and transferred to the male. As a result the male is not able to increase reproductive success by mating with multiple partners. Therefore which of the following about sexual selection in this species is not true? Females are more likely to develop traits that signal genetic quality to males. Females will be able to increase reproductive success with increased mating partners. Sexual selection in males will lead them to be choosy with what females they mate with. Sexual selection in males will lead them to mate indiscriminately when they find a female.Explain how sexual selection might lead to a)sexual dimorphism and b) members of one sex (usually male) having traits that do not enhance their survival
- Bigger dogs will have more puppies than smaller dogs in a litter. What is the independent variable, dependent variable, constant, and control group?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 maturityPlease discuss the fitness advantage associated with aiding a related or even an unrelated individual with producing offspring. Please give examples.
- The theory of kin selection (inclusive fitness) takes into account that an organism can pass on copies of its genes through the reproduction of close relatives. True or FalseExplain the following terminologies and theories. Give an example or a situation that will further explain the following. Birth rate Extra-uterine Life Infant Mortality Parental Investment Theory Life History Theory Life Cycle Darwinian Fitness Parent-Offspring Conflict Sibling RivalryDescribe thoroughly the selective advantages and disadvantages organisms that reproduce sexually have over those that reproduce asexually, as well as the ramifications of mate choice on the traits present in species. The following questions could help answer the question above. What are the advantages of sexual reproduction? What are the disadvantages? How do traits selected by sexual selection and those selected by differential survival mix in an animal species? i.e. is it more important to mate or survive? Use specific examples to illustrate your point. Your answers should indicate an understanding of the mechanism behind natural selection. Propose a scenario where asexual reproduction would be favorable.
