A very large population of randomly-mating bunnies exists near the foothills of a local town. A hiker notices that the vast majority of the bunnies have fluffy, white tails. However, the hiker also spots some bunnies with fluffy, grey tails. White tails are dominant to grey tails. The hiker counts all of the bunnies in the foothills (because he clearly ran out of other things to do in life) and finds that out of 720 bunnies only 35 have grey tails. Using this information calculate a) the allele frequencies and b) the genotype frequencies for this population.

answer; i believe the correct answer to the above question is ( friction)

substitution is the answer in this case

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
