Which of the following might be symptoms of a lesion to the right motor cortex?
a) loss of movement of the left leg
b) loss of movement of the right leg
c) loss of movement of the head and trunk
d) complete loss of bladder control

loss of movement of the left leg

Explanation:

The main function of the brain motor cortex is the regulation of body movements. This area of brain controls the voluntary movements of the body.

Right half of the body controls the left side of body and left half of the body controls the right side o body. Any lesion in right motor cortex may cause the loss of movement of left leg.

Thus, the correct answer is option (A).

it is a learned trait

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.
