Chapter 7 ELEMENTS OF MICROBIAL NUTRITION, ECOLOGY, & GROWTH.
BW- Paper Lab BACKGROUND: In water, carbon dioxide dissolves to form a weak acid. As a result, an acid-based indicator such as bromothymol blue can be.
Review Hydrophobic (non polar) Hydrophilic (polar)
Chemical Compounds in Cells Essential Questions: What are elements and compounds? What are the main kinds of organic molecules in living things? How is.
Chapter 25: Metabolism. Introduction to Cellular Metabolism Figure 25–1 Formation of Organic Molecules Energy production begins in cytosol Energy is captured.
Proteins: Structure reflects function….. Fig. 5-UN1 Amino group Carboxyl group carbon.
1 Chapter 11 Chemical Reactions. 2 Section 11.1 Describing Chemical Reactions Objective 1: You will learn to identify when a chemical reaction takes place.
Acids, Bases, & Salts What is an ACID? pH less than 7 Neutralizes bases Forms H + ions in solution Corrosive-reacts with most metals to form hydrogen.

Ch 11 Acids & Bases Test Review. 1.Color Change; Universal indicator- yellow, orange and red Blue Litmus paper turns red 2.) Sour taste and conducts.
Photosynthesis A summary of what you should know.
Anatomy and Physiology Chapter #2. Molecules and Compounds A molecule is formed when two or more atoms combine. If atoms of different elements combine,
Chapters 8 & 9 Photosynthesis and Cellular Respiration.
Identifying Types of Chemical Reactions. Synthesis (Combination) Reactions Synthesis: A synthesis reaction is when two or more elements or simple compounds.
EMB agar Only gram-negative bacteria grow on EMB agar. (Gram-positive bacteria are inhibited by the dyes eosin and methylene blue added to the agar.) Based.
Microorganisms Microbes too small to be seen with the naked eye aggregations or colonies can be seen without the aid of a microscope.
PH Scale: a standard measurement of the concentration of hydrogen ions (H + ) in a solution (0-14) Neutral solutions: pH of 7 (H 2 O) Acidic solutions:
Unit 3 Structure and Function Notes Part 1 Its Alive or, Is It? M. Elizabeth Martin Luther King, Jr. JHS 2006.
PH This is a rough measure of the acidity of a solution. The "p" stands for "potenz" (this means the potential to be) and the "H" stands for Hydrogen.
Basic Chemistry Chapter 2. Atoms Matter All matter is made of atoms All matter is made of atomsAtoms Atoms consist of electrons, protons, and neutrons.
Aim: What are the compounds important to living things? The physical and chemical properties of water make it unique and necessary for living things Water.
