A Punnett square (shown below) is used to predict eye color with blue eyes being recessive and brown eyes being dominant, but the parents have 4 children all with brown eyes. How would you explain this?

Brown eyes are dominant

Explanation:

There is approximatley a 25% chance of children having blue eyes, but that doesn't necessarilly mean that 1 in 4 will have blue eyes. It's actually more likely to have the dominant gene.

Answer/Explanation:

Because blue eyes are a recessive gene? So like if both parents have brown eyes (Dominant gene) Then that gene sort of "overpowers" the blue gene? Also, no matter how many children they have it doesn't mean, that one of them might not get blue eyes if both parents carry blue eye genes. They also could just end up with only brown eyed children, it's almost like spinning a wheel of fortune tbh lol

I find this sort of stuff hard to explain but I hope what I said helps you out :)

human didn't come from monkeys man i hate these stupid teachers

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.
