Cells have membranes that allow them to establish and maintain internal environments that are different from their external environments. The structure of the phospholipid bilayer influences its permeability.

Which statements accurately reflect the permeability of the cell membrane? Choose all that apply.

The hydrophilic part of the cell membrane is A, the phosphate head.
The lipid tails are hydrophobic and will only allow molecules which are small and polar to pass through.
Molecules that are large or charged must use a channel protein, such as D, to cross the cell membrane.
Molecules using membrane proteins, such as E, for transport require energy.
Charged molecules, such as K+ or Ca++ are unable to pass through the lipid bilayer because of their charge and must use a membrane protein to cross the cell membrane.
C, the lipid tails, are hydrophobic and repel water.

answer; i believe is(b)converging

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.

d. groundwater flows through the subsoil and deposits minerals.
