Polyunsaturated fats have fewer hydrogen atoms than do saturated fats

Explanation:

A saturated fatty acid has the peak of a feasible amount of hydrogen atoms joined to every carbon atom. Meanwhile, some fatty acids, a mixture of hydrogen atoms in the center of a chain is missing, building a gap that leaves two carbon atoms appended by a double bond preferably than a single bond. Because the chain has fewer hydrogen atoms, it is assumed to be "unsaturated."Unsaturated fat has one or more double bonds. If a fat molecule has one double bond, it’s called monounsaturated fat, but if it has higher than one, it’s called polyunsaturated fat. Polyunsaturated fats are normally liquid at room temperature. In foods of plant origin and remarkable seafood, a huge proportion of the fatty acids are monounsaturated and polyunsaturated.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
