Water and Life Chapter 3 Overview: The Molecule That Supports All of Life Water is the biological medium on Earth All living organisms require water more than any other substance Most cells are surrounded by water, and cells themselves are about 70?95% water The abundance of water is the main reason the Earth is habitable ? 2011 Pearson Education, Inc. Figure 3.1 Polar covalent bonds in water molecules result in hydrogen bonding The water molecule is a polar molecule: the opposite ends have opposite charges Polarity allows water molecules to form hydrogen bonds with each other ? 2011 Pearson Education, Inc. Figure 3.2 Hydrogen bond Polar covalent bonds ? ? ? + ? + ? ? ? ? ? + ? + ? ? Four emergent properties of water contribute to Earth?s suitability for life

Study the water molecules at the right. On the central molecule, label oxygen (O) and hydrogen (H). 2. What is a polar molecule? Why is water considered polar? 3. Now, add + and ? signs to indicate the charged regions of each molecule. Then, indicate the hydrogen bonds. 4. Explain hydrogen bonding. How many hydrogen bonds can a single water molecule form?

Introductory Questions #1 Name the seven main properties of life. (Pg. 3) Which of the hierarchial levels of biology is the lowest in regard to carrying on and sustaining all life activities and is the fundamental unit of life? (pg 5) Introductory Questions #1 3. In your own words briefly describe what ?emergent properties? are. 4. How is negative feedback different from positive feedback? (pg. 11) What do these mechanisms do for a living thing? 5. Name the three domains of life. Which domain includes four out of the six kingdoms of life? 6. Why is natural selection considered the ?mechanism? for evolutionary adaptations to occur? 7. How is a hypothesis different from a theory?

preAP Chem 2013-2014 1 NOTES: Energy in Chemical Processes Name ______________________________ Period ________ Energy and Heat ? Energy is defined as the ability to do _________ or produce ___________; the sum of all potential and kinetic energy in a system is known as the internal energy of the system. It comes from the energy stored in ____________ (______________ energy) and from the ____________ of atoms and molecules (______________ energy). ? Heat is defined as the ______________ of energy from a warmer object to a cooler object. Do not confuse the terms heat and temperature. Heat is the _____________ of the energies of the molecules

Properties of water

Water Potential (?) Water potential (?) is a measure of water?s potential to do work. In order to do work, an object must be able to apply enough force to another object to cause displacement. In order for water to displace another object, water must be moving. The largest water potential any volume of water can have, if only standard atmospheric pressure is being applied to that volume of water, is defined as 0. This is the water potential for distilled water. Distilled water has the greatest potential to move, and thus displace another object.

Campbell's Biology, 9e (Reece et al.) Chapter 3 Water and Life Life evolved in the ocean, and the chemistry of life occurs in an aqueous environment. These questions explore the properties of water that are important to sustain life?s chemical processes, organismal physiology, and interactions of organisms with their environment. Quantitative properties such as heat content, molarity, and pH are also addressed. A few questions address how human activities affect the global environment through acid rain and acidification of the ocean. Multiple-Choice Questions 1) In a single molecule of water, two hydrogen atoms are bonded to a single oxygen atom by A) hydrogen bonds. B) nonpolar covalent bonds. C) polar covalent bonds. D) ionic bonds. E) van der Waals interactions.
