The human MN blood group is determined by two codominant alleles, M and N. The following data were obtained from various human populations:

Percentages*
Population Place MM MN NN
Inuit East Greenland 83.5 15.6 0.9
Navajo Indians New Mexico 84.5 14.4 1.1
Finns Karajala 45.7 43.1 11.2
Russians Moscow 39.9 44.0 16.1
Aborigines Queensland 2.4 30.4 67.2

a. Calculate the allele frequencies in these five populations.
b. Which populations appear to be in Hardy-Weinberg equilibrium?

i believe you meant to say air rather than hair so the answer is below ")

the dead sea, the lowest place on earth at 430 metres (1,410 ft) below sea level, has a correspondingly high typical atmospheric pressure of 1065 hpa.

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.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
