"Overseeing the postural muscles of the body and making rapid adjustments to maintain balance and equilibrium are functions of the "

The correct answer is : The cerebellum.

Explanation:

The cerebellum is located under the cerebrum at the back of the brain. It is the part of the central nervous system that receives the information from the sensory systems to the different parts of the brain and spinal cord.

The major function of the cerebellum is to maintain postures, regulates muscle movements and balance. Other role of the little brain is to control speech, coordination.

Thus, the correct answer is - the cerebellum.

not sure but try c two haploid cells

explanation:

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.
