The cell membrane is composed of a phospholipid bilayer.
The cell membrane is primarily composed of a mix of proteins and phospholipids
Phospholipids are a major component of cell membranes. They a head and a tail. The head is hydrophilic (attracted to water) and the tail is hydrophobic (repelled by water).
They form a bilayer in which their hydrophilic heads face the aqueous cytosol and extracellular fluid while their hydrophobic tails face away from the cytosol and extracellular fluid.
The lipid bilayer is semi - permeable
Bones: they lose calcium, becoming crispy
Muscle: they lose mass
Cartilage: becomes stiffer, but it does not make airway more rigid
D) connective tissue: It includes bone, blood, and lymph tissue, giving support to the skin and internal organs, becoming increasingly stiff when aging.
It should be connective tissue.

Answer:</h2>
The principle is <u>4) Archimedes' principle</u>.
<h2>
Explanation:</h2>
Archimedes principle, found by the old Greek mathematician and creator Archimedes, expressing that any object totally or incompletely submerged in a liquid (gas or fluid) very still is followed up on by an upward, power the size of which is equivalent to the heaviness of the liquid dislodged by the body.
The volume of dislodged liquid is identical to the volume of an item completely drenched in a liquid or to that portion of the volume underneath the surface for an article halfway submerged in a fluid. The heaviness of the uprooted bit of the liquid is comparable to the extent of the buoyant force.
