In which of the following scenarios would energy be mostly derived from anaerobic metabolism? a. when an athlete is in a steady state or at restb. when an athlete begins an activityc. when an athlete experiences temporary fatigued. when an athlete reduces the duration of an activity

Option C

Explanation:

The situation of fatigue occurs in an athlete when he/she is doing rigorous exercise or an activity requiring intense muscular activity. In these scenarios, muscles cells undergo anaerobic respiration which eventually leads to acidification and hence fatigue in muscles. Also during this scenario, the resting membrane potential of the muscles depolarizes and muscle may deplete in severe cases. Thus, during temporary fatigue muscle experiences highest level of anaerobic respiration.

Option C is correct

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.
