Which of the following is an example of natural selection? Is the answer pesticides are spreading a field resulting in an increase in crop growth and a decrease in insect population?
7 answers
No, the example provided is not an example of natural selection. Natural selection is the process by which organisms better adapted to their environment tend to survive and reproduce more successfully, leading to evolutionary changes in a population over time. The example given is more related to human intervention in the ecosystem, and not the result of natural selection.
is the answer Cricket frogs preferred to sleep during the day while red eyed tree frogs preferred to sleep during the night?
Yes, the example of cricket frogs preferring to sleep during the day while red-eyed tree frogs prefer to sleep during the night is an example of natural selection. This behavior is likely the result of evolutionary adaptations that have allowed these species to better survive and thrive in their respective environments by avoiding predators and maximizing their opportunities for survival. Over time, these different patterns of behavior have likely been favored through natural selection.
Is the answer to produce a more desirable fruit a farmer crosses a tree that produces sweet oranges with a tree that produces large oranges?
No, the example provided is not an example of natural selection. In this case, the farmer is using artificial selection (specifically, crossbreeding) to produce a more desirable fruit. Natural selection, on the other hand, involves the process by which traits that increase an organism's chances of survival and reproduction in a specific environment are passed on to future generations. Artificial selection involves humans actively selecting and breeding organisms with desired traits for specific purposes.
Is the answer rabbits with a mutation for longer thicker for survive and unusually cold winter while many normal rabbits do not survive?
Yes, the answer is: rabbits with a mutation for longer, thicker fur survive an unusually cold winter while many normal rabbits do not survive.
This is an example of natural selection, where individuals with a specific trait (in this case, longer and thicker fur) are better able to survive and reproduce in a particular environment (cold winter conditions). Over time, the offspring of these individuals are more likely to inherit and pass on the beneficial trait, leading to an increase in the population of rabbits with longer, thicker fur.
