Introduction The purpose of this lab was to identify unknown bacteria cultures using various differential tests‚ and my unknown bacteria is #17. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures. The differential

before‚ like cells. A cell is the basic unit of life. All living things are made of cells. All cells come from preexisting cells through a process called cellular division. There are two types of cells‚ eukaryotes and prokaryotes. Prokaryotes are very simple and small. They are unicellular and have no membrane bound organelles. Their DNA is found directly in the cytoplasm since they have no nucleus. Eukaryotes are much more complex and bigger. They have membrane bound organelles for specific functions

Ancient cultures in the past have used simple machines to decrease the amount of force needed to build large structures. Simple machines were created to make work easier by changing force‚ distance‚ or direction. The six simple machines are inclined plane‚ wedge‚ screw‚ lever‚ wheel and axle‚ and pulley. With the help of these machines different tribes and groups have created many common structures we know today. Simple machines have changed society in many ways and lead to the creations of famous

„Strategy as Simple Rules“ by Kathleen Eisenhardt and Donald Sull A) Article Summary Basically the article describes how and why companies like Yahoo‚ AOL or Enron use simple rules in rapidly moving markets. In the past companies were able to apply complex strategies due to a simple business landscape and stable markets‚ but nowadays most markets are not stable any more. Markets are fast moving and so complex themselves that companies are forced to react and to simplify their strategies.

Krupa Desai Cell Biology April 3‚ 2013 Lab: Biosynthesis of Starch Introduction: In this lab we learned the concept and procedure of synthesizing starch. We also learned the effects of pH and temperature on the reaction rates of amylase.. In the process of the synthesis lab we learned phosphorylation using a potato‚ which was what we synthesized. The phosphorylation took place after the addition of primer. There are two different types of starches used are amylose and amylopectin. To test

activitys that we do every day in the course of our normal lives. Lowering our energy use and reducing our emisions of greenhouse gasses can be very simple. Let’s begin with water. Every drop of water that we use requires energy to filter‚ purify and pump into our homes. How much water do you use every month and how can you lower that usage? Some simple solutions include water saving showerheads and faucets‚ more efficient toilets‚ dishwashers and washing machines‚ and even just turning off the water
