If the critical concentration of the plus end of a representative microfilament is 3 (ignore the units), and the critical concentration of the minus end of that microfilament is 18, what would be the behavior of this microfilament if the actual concentration of available ATP-bound G-actin at both ends is 18?

1.The microfilament will be polymerizing at the plus end and exhibiting no net growth at the minus end.
2.The microfilament will be polymerizing at the plus end and depolymerizing at the minus end.
3.The microfilament will be polymerizing at both ends.
4.The microfilament will be depolymerizing at both ends.
5.The microfilament will be depolymerizing at the minus end and exhibiting no net growth at the plus end. F.
6.The microfilament will be polymerizing at the minus end and depolymerizing at the plus end.

the answer would be knowledge about cars!

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.

i believe it would be c: tons.
