colony of E.coli needed for the experiment. A sterile innoculating loop was gently scraped over the colony and transferred into the tube with the calcium chloride‚ by gently twirling the tube in the solution. Using the capillary micropipette and plunger‚ 10 picometers of the plasmid PUc8 solution with the resistant gene was added to the tube labeled positive. Gently give a few taps to the tube labeled positive to mix the plasmid solution. Both of the tubes were placed in an ice bath for 15 minutes

An elevator is a mechanism for moving people and freight from level to level in a building or any other structure. The first elevator-like structure was built in 236 BC by the Archimeds. This construction was a hoist operated by ropes and pulleys. However‚ the first pragmatic elevator was not developed until the 19th century. Though sensible‚ this elevator has been modified many times throughout the course of history and is still updated with all of the new advancements in math and technology

Inventions of the Renaissance Clocks The first mechanical clock was invented in the early 1300’s. With this invention time began to be measured in hours (24 hours equaling a day). Galileo‚ an Italian scientist‚ discovered the pendulum in 1581. The pendulum greatly improved the constant movement of the hands or bell of a clock. The average error with the pendulum varied only by seconds each day. Before this the error was from 10 to 15 minutes a day. During the 1600’s the metallic gear‚ or toothed

AP Biology Dissolved Oxygen and Aquatic Primary Productivity Purpose: To measure and analyze the primary productivity of natural waters of laboratory cultures using screens to simulate the decrease of light with increasing depth. Background: Dissolved oxygen (DO) is how oxygen is measured. Oxygen is required in cellular respiration‚ so it is very important for aquatic life. When more oxygen is consumed than is produced‚ dissolved oxygen levels decline and some animals could die if they do not
