An organelle is a cellular structure which performs specific functions within a cell. Organelles are important to the cell as cells would not be able to function without them: even the most common organelle - the nucleus. A cell without a nucleus cannot function (except prokaryotes, as they have an undefined nucleus)

Answer:
The three main types of lipids are - triglycerides, diglycerides, and steroids.
Explanation:
Lipids are organic compounds that are fatty acids or their derivatives. Lipids are insoluble in water but soluble in organic solvents (alcohol, ether). The three common lipids are triglycerides, diglycerides, and steroids.
An ester derived from glycerol and three fatty acids is a triglyceride. These are the main component of body fat in the vertebrates as well as the vegetable fat.
A Glyceride consisting of 2 fatty acid chains bonded to a glycerol molecule covalently through ester linkages is a diglyceride.
Biologically active organic compounds with four rings arranged in a specific molecular configuration are steroids.
Explanation:
The virus killed people directly by causing massive hemorrhages and edema in the lungs. Modern analysis has shown the virus to be particularly deadly because it triggers a cytokine storm (overreaction of the body's immune system
