Answer 1

A nonpolar solvent is made up of molecules that do not have a dipole.

23. Lipids play a role in the body as well as in food. Lipids provide nutrition, control hormones, relay nerve impulses, cushion vital organs, and carry fat-soluble nutrients throughout the body.

24. The base of a fat molecule is made up of glycerol, and the tails are made up of three fatty acids. A fatty acid is made up of a long hydrocarbon chain bound to a carboxyl group, while glycerol is a compact organic molecule with three hydroxyl (OH) groups.

25. Saturated fats contain only single bonds in the carbon chain

26. Unsaturated Fat

27. plasma membrane

28. Oils and fats, also referred to as lips in science, are amphipathic compounds. They have both hydrophilic (water-loving) and hydrophobic (water-fearing) sides, which means one side needs to be near water while the other does not.

29. Steroids are a kind of lipid molecule distinguished by its four fused rings arrangement. Steroids are classified as lipids because they are hydrophobic and insoluble in water, despite their structural differences from other lipids.

31. Testosterone is an anabolic steroid and the main male sex hormone.

The biosynthetic counterpart to animal steroids, lanosterol.
