Identify three components of the plasma membrane other than phospholipids

Asides from phospholipid (which is made up of two fatty acid tails, and a phosphate-linked head and glycerol), the plasma membrane also has the following components:

1. Cholesterol (Which together with phospholipids form the lipid bilayer)

2. Proteins

3. Carbohydrate Groups

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
