Answer:
B i hope this help
Explanation:
The cell membrane consists primarily of a thin layer of phospholipids which spontaneously arrange so that the hydrophobic "tail" regions are shielded from the surrounding polar fluid, causing the more hydrophilic "head" regions to associate with the cytosolic and extracellular faces of the resulting bilayer. This forms a continuous, spherical lipid bilayer approximately 7 nm thick, barely discernible with a transmission electron microscope.
The arrangement of hydrophilic and hydrophobic heads of the lipid bilayer prevent polar solutes (e.g. amino acids, nucleic acids, carbohydrates, proteins, and ions) from diffusing across the membrane, but generally allows for the passive diffusion of hydrophobic molecules. This affords the cell the ability to control the movement of these substances via transmembrane protein complexes such as pores and gates.

Answer:Acoustic Neuroma (Vestibular Schwannoma)
Explanation:An acoustic neuroma is a noncancerous brain tumor that develops on the nerve that runs between the inner ear and the brain. Also called vestibular schwannomas, acoustic neuromas develop in cells known as Schwann cells. The primary symptoms of vestibular schwannoma are unexplained progressive unilateral hearing loss and tinnitus(the perception of sound when no external corresponding sound is present) and vestibular (disequilibrium) symptoms.
