. The land snails of the species Cepaea nemoralis have shells that differ in color and number of stripes. Snails with light colored, striped shells are found mainly in well-lighted areas, and dark colored snails lacking stripes are found in shady places. Shell color serves as camouflage for the snails. Some dark colored striped snails are also found in the population but this intermediate form doesn’t allow them to easily camouflage in the environment. Define the type of natural selection that is occurring here and provide another example of it.

3points hurry! what is the relationship between biotechnology, sharkskin, and disease resistance? bioengineers have developed an artificial sharkskin that does not allow resistant bacteria to grow on it. disease-causing microbes have been genetically modified to keep them from infecting the skins of sharks. scientists have created a device that can be attached to the skins of sharks that dramatically increases their abilities to resist disease. sharkskin produces many chemicals that can be collected and used to create antibiotics.
