. 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.

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom

protist eukaryotes that are not plants, animals, or fungi ("misfits")

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
