The light moths declined in number and the dark colored moths increased in number. There is fossil evidence that this . This allows the farmers to spray their fields to get rid of weeds without harming their crops. They were therefore able to eat aquatic plants and get enough food to survive and reproduce.Ducks with more webbing were better at eating aquatic plants than ducks with less webbing, so the ducks with more webbing survived and reproduced better than ducks with less webbing.Ducks with less webbing needed to grow more webbing in their feet in order to improve their access to aquatic plants, which allowed them to survive better and reproduce more.Q6.10. b. just other multicellular animals.

Why is sexual selection likely to result in more rapid changes in phenotype than typical natural selection in the same population? Yes, some individuals with certain traits are more likely to survive and pass Consider also that the environment that this organism lives in changes for the worse. (a) Two or more unrelated species change independently of each other and the environment in which they live (b) Two or more related species change to become less similar due to living in different environments (c) Two or more. To put this another way: all humans have the same genes, yet we do not look alike. Every plant or animal belongs to a species.

How do modern biology, evolution, and natural selection explain why there are differences in innate aptitude in animals (such as there are humans who are smarter than others, some are more artistic than others, etc.)? The most common mechanism for this is natural selection, in which individuals with beneficial heritable traits reproduce more than organisms without these traits, causing an increase in the frequency of the trait within the population. There must be a sudden environmental change. Calculate the concentration in units of ppb and determine whether the sample exceeds the legal limit of 10.0 ppb. Be as specific as possible.
