1) pH of the lemon juice is between 2 and 3, which is a low pH (acidic) due to the presence of citric acid, so the answer is false.
2) Protons and neutons reside in the nucleus, the electrons orbit the nucleus. So, the answer is Electrons.
3) Molecules that are attracted to water are called hydrophillic. Hydro - water, phillic - loving, which literally translates to waterloving.
4) The ability of an organism to maintain a stable equillibrium is called Homeostasis. Regulation of glucose in the body to remain constant is an example of homeostasis.
5) Ionic bonding occurs when two atoms are held together.
6) Human sex hormones are examples of steroids.
7) Nacl is an ionic compound and they have ionic bond.
8) Lipids do not dissolve in water, as they are hydrophobic. The answer is dissolves lipids.
