Answer:c. Steroids/cholesterols and phospholipids
Explanation:
The cell membrane structure exhibit a fluid mosaic model due to the presence of two types of membrane lipids these are phospholipids and sterols like steroids/cholesterols.
A phospholipid is a kind of lipid that is made up of glycerol, two fatty acids in tail and a head group associated with the head group. The biological membrane forms two layers of phospholipids with their tails that points inwards and the arrangement is called as the phospholipid bilayer.
The cholesterol is the another membrane lipid in the cell membrane. It is composed of fused carbon rings present along the side of phospholipids.
A hot spot is here magma appears near to the surface. Imagine this, the crust is a plate, and the hotspot is a pencil, as the plate moves, you punch holes through the plate. This is the hotspot creating volcanoes as the crust moves. This is how hotspot volcanoes are created. The volcanoes that are created on boundaries are created from differences in the crust as it is created.
If the forces are unequal and acting in different directions, you subtract the smaller number from the bigger number. Forvexample, 5 newtons-3 newtons=2 newtons. The object moves in the direction the bigger number is pointing.
