Assignment #1 Chapter 2 1. B an atom 2. C an ion 3. D ionic, covalent, and hydrogen 4. B it can form four single covalent bonds 5. D all of the above 6. A hydrogen bonds between the individual water molecules 7. C heat storage and heat of vaporization 8. A cohension 9. A (1) acids and (2) bases 10. B a buffer takes up H+ from the solution 1. 2000 years 2. N2 is one of the strongest covalent bonds. That means it requires a great deal of energy to break. The majority of Nitrogen in living things have is bacterium, but cannot be used until the bond is broke down. Chapter 3 1. B proteins, carbohydrate, lipids, and nucleic acids 2. B simple sugar 3.

A cells are the smallest living things; nothing smaller than a cell is considered alive 2. B a double lipid layer with proteins inserted in it, which surrounds every cell individually 3. D prokaryotes,eukaryotes 4. A a nucleolus 5. C endoplasmic reticulum and the Golgi complex 6. D mitochondria and the chloroplasts 7. B eukaryotic cells in plants and fungi, and all prokaryotes have a cell wall. 8. D slowly disperse throughout the water; this is because of diffusion 9. D facilitated diffusion and active transport 10. C energy and specialized pumps of channels 1. The flat cell has a greater surface area. Therefore it can carry more materials. 2.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
