Lola has a condition where mucus builds up in her lungs. this makes it more difficult for gas exchange to take place , which two organ systems are primarily affected from this?
A. nervous and musculoskeletal
B. Respiratory and reproductive
C. circulatory and respiratory
D. Circulatory and digestive
PLEASE HELP I AM LOSTT

The answer would be C. Circulatory and respiratory

Explanation:

You can rule out A because the nervous system would not be affected by this. You can also rule out B because it would not affect the reproductive system in any way. D is ruled out because the digestive system is also not affected which leaves you with C

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.
