Answer:
The answer is: phospholipid molecules
Explanation:
The plasma membrane of a cell is consists of a lipid bilayer. This lipid bilayer, also known as the phospholipid bilayer, is a polar membrane composed of two layers of lipid molecules, usually amphipathic phospholipid molecules.
The amphipathic phospholipid molecules have a hydrophilic phosphate head on the exterior and a hydrophobic tail consisting of fatty acid chain on the interior of the membrane.
Molar mass Na = 23g/mol
46g = 456/2 = 2mol
1mol = 6.022*10^23 atoms
2mol = 2*6.022*10623
= 1.204*10^24 atoms
Answer:
When objects collide, energy can be transferred from one object to another, thereby changing their motion. Energy can also be transferred from place to place by electric currents, which can then be used locally to produce motion, sound, heat, or light.

the triangle that is formed by the 3 towns is an equilateral triangle, so that
the center will have the same distance in each town. Assuming an equilateral
triangle, the center is at 1/3 of the height of the equilateral triangle </span>
Answer:
Radiation is the emission of electromagnetic waves from all matter that has a temperature greater than absolute zero. In other words the heat of the energy it radiates in infrared spectrum.
