33. Lipids are classified into three categories triglycerides, steroids and phospholipids.
Triglycerides are lipids obtained from food sources of fat. It keeps us warm while protecting your internal organs with a layer of padding.
Steroids are a type of lipid which includes hormones and cholesterol. Cholesterol is produced by the body and consumed through food, and it plays a role in the production of hormones.
Phospholipids are very similar to triglycerides, but slightly different on a molecular level. It is located on cell membranes and form double-layered membranes with the water-soluble molecules on the outside of the cell membrane.
34. The correct option is nitrogen.
After oxygen, carbon and hydrogen, nitrogen is the most essential element required for the human body.
35. Cellulose makes up the cell wall of plants. This provides the strength to the plants and trees.
36. The sun is the global environments supporting life on earth.
