Helicobacter pylori (H. pylori) is a helically-shaped bacterium that is usually found in the stomach. It burrows through the gastric mucous lining to establish an infection in the stomach's epithelial cells (see photo). Approximately 90% of the people infected with H. pylori will never experience symptoms. Others may develop peptic ulcers and show symptoms of chronic gastritis. The method of motility of H. pylori is a prokaryotic flagellum attached to the back of the bacterium that rigidly rotates like a propeller on a ship. The flagellum is composed of proteins and is approximately 40.0 nm in diameter and can reach rotation speeds as high as 1.50 x 103 rpm. If the speed of the bacterium is 10.0 µm/s, how far has it moved in the time it takes the flagellum to rotate through an angular displacement of 5.00 × 10² rad? H.

A certain strain of bacteria will divide itself from 1 to 2 every to [minute]. As a result, its population can be modeled as N (t) = No2. ---(eq 1) N(t) is the population at time t, NO is the population at the beginning = 100, t = time you wait [minute]. You prepare 6 dishes. Each dish contains 100 living bacteria at the beginning. Then you wait for 20 mins, freeze the first dish to stop the bacteria in the dish from growing. Then wait for another 20 mins, freeze the second dish (i.e. the total growth time for the second dish is 40 min). Proceed to the next dish in the similar process until all 6 dishes are done. After counting all the dish, you collect the data between time and population as follow: t(min) N(t) 20 132 220 40 60 311 80 369 100 622 120 836 Find to (the time for bacteria to divide itself). Answer in [min] Note: if you apply log function on both sides of eq 1 you get In (N (t)) =t. n2 + In(No). ---(eq 2)
3. A "colloid probe" mode is used in AFM to measure the adhesion. A sphere is attached to a tipless AFM cantilever. Whichcapillary force do you generate when probing hydrophilic surface with hydrophilic colloid probe of 2 microns in radius? Compare your results for relative air humidity of 90% and 30%.

Capillaries Explain the direction and the rate of flow in the capillaries. Does the rate remain constant or does it fluctuate from time to time? Does the direction of blood flow ever change? What limits a capillary from being smaller than a certain size? Are any capillaries dead-end sacs? Are all cells directly adjacent to a capillary, thus providing a simple passage for food, dissolved gasses, and wastes?
