2. In series, we add the resistance up
Use the formula V = IR to find the current.
R = 10+4 = 14, V=42
42=I (14)
I = 42/14 = 3 A
3. Closed
4. Answer B

The answer is phospholipids. The phospholipids are a group of lipids that are main constituent of all cell membranes in which they can make lipid bilayers because of their amphiphilic feature.
