Hich of the following describes the structure and function of the cell membrane? a. the hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. the hydrophobic tails form an oily layer inside the membrane that keeps water out of the cell. b. the hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. the hydrophobic tails form an oily layer inside the membrane that allows water to enter the cell. c. the hydrophobic head groups of the lipid molecules are exposed to the outside of the cell, which is a water-like environment. the hydrophilic tails form an oily layer inside the membrane that keeps water out of the cell. d. the hydrophobic head groups of the lipid molecules are exposed to the outside of the cell, which is a water-like environment. the hydrophilic tails form an oily layer inside the membrane that allows water to enter the cell.

The correct answer is: A. The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. The hydrophobic tails form an oily layer inside the membrane that keeps water out of the cell.

Plasma membrane of the cell is arranged in a bilayer of phospholipids. Phospholipids are amphipathic molecules which means that they have both hydrophilic and hydrophobic regions. The hydrophilic heads of phospholipids that are faced outward and hydrophobic layer located in the interior of the bilayer together make a good barrier between the interior and exterior of the cell, so the water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane.

hello there,

igneous rock formed from below the surface would have more crystals because

answer: because magma cools more slowly than lava

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
