Western spadefoot toads breed and deposit their fertilized eggs in small, often short-lived ponds. The tadpoles grow in the ponds for a period of time before undergoing a metamorphosis into an adult frog. One unusual characteristic of spadefoot tadpoles is the ability to change body form during development. Normally most tadpoles are herbivorous and feed on plant material. However, when conditions in the ponds suggest they are beginning to dry up (e.g., an increase in water temperature or concentration of organic waste), a small percentage of individuals in the population undergo a dramatic change in body form and habit and begin to eat their competitors. This ability is considered to be advantageous as it both reduces the number of competitors in the pond and speeds up the rate of development of the transformed tadpoles.If global climate change continues (as predicted) to increase the average temperature of habitats around the world, how would populations of spadefoot toads likely evolve in response to an increase in pond temperatures?-Spadefoot toads would likely evolve to lay fewer eggs to try and offset the increase in the mortality rate.-Spadefoot toads would likely evolve to increase the period of tadpole development.-Spadefoot toads would likely evolve to have a higher percentage of tadpoles be herbivorous.-Spadefoot toads would likely evolve to have a higher percentage of toads become carnivorous.Spadefoot toads would likely evolve to have a higher percentage of toads become carnivorous.Male peacocks compete with one another to mate female peacocks. Males with more colorful tail feathers attract female mates at a higher rate than those without.Therefore, male peacocks have colorful tail feathers, whereas female peacocks do not.What is this an example of?-sexual selection -artificial selection -gene flow -genetic drift sexual selection

A gardener maintains a species of rose that produce either yellow flowers (the dominant phenotype) or white flowers (the recessive phenotype). One day, the gardener observes that a cross between two yellow rose bushes has led to a single rose bush with orange flowers.What evolutionary mechanism is involved in the change in the gene pool of this species?-mutation -gene flow -genetic drift -artificial selection mutation The cladogram below depicts relationships between
