- QUESTION 1 You are reading the results of a motility test tube that was incubated for 48 hours at 37 C. You look at the tube and see a red diffused color radiating away from the inoculation line. How would you interpret these results? OA. No growth. B. No motility. OC. Motility. OD. It is a mixed culture. QUESTION 2 You are trying to determine if a bacterial isolate is motile. What tool should you use to inoculate the motility test agar tube? OA Inoculating loop OB. Sterile swab OC. Inoculating needle OD.

- (a) About how many microorganisms are found in the human intestinal tract? (A typical bacterial length scale is one micron = 106 m. Estimate the intestinal volume and assume bacteria occupy one hundredth of it.) (b) Discuss your answer to part (a). Are these bacteria beneficial, dangerous, or neutral? What functions could they serve?arrow_forwardThe Half-life of Pennies Lab Can you use pennies to demonstrate "decay? Imagine existing more than 5,000 years and still having more than 5,000 to go! That is exactly what the unstable element carbon-14 does. Carbon-14 is a special unstable element used in the absolute dating of material that was once alive, such as fossil bones. Every 5,730 years, half of the carbon-14 in a fossil specimen decays or breaks down into a more stable element. In the following lab you will see how pennies can show the same kind of "decay." Materials • 100 pennies • large container with a cover Procedure a. Place 100 pennies in a large, covered container. Shake the container several times and remove the cover. Carefully empty the container on a flat surface, making sure the pennies don't roll away. b. Remove all the coins that have the "head" side of the coin turned upward. Record the number of pennies removed and the number of pennies remaining in the data table below. Shake number Number of coins removed…arrow_forward(a) What is the order of magnitude of the number of micro organisms in the human intestinal tract? A typical bacterial length scale is 106 m.

(c) In 2.000 y?arrow_forwardWhen we use petrol we are ultimately using stored energy from the sun. Plants capture the energy when growing, and then through a long process of decay and compression this plant matter is converted into a fossil fuel. An interesting question is how much sunlight is needed to produce a quantity of petrol. To estimate this, let's assume the petrol has come from wood, and let's assume we have a fast-growing wood source such as Pinus radiata. Assume also: a mature tree contains around 3 m3 of timber; a tree is harvested when 35 years old; the density of wood is around 500 kg/m3; 2 kg of wood makes 1L of petrol; a tree receives on average 8 hours of sunlight per day. How many "hours of sunlight" are stored in 1L of petrol? i.e. how many hours of sunlight does a tree need to be exposed to, to produce the amount of wood needed to make 1 L of petrol? Give your answer to two significant figures.arrow_forward2. Bread is a good source of carbohydrates. Bakers use yeast to leaven the bread. Explain why the bread rises.arrow_forward
- 45. Insects do not have lungs as we do, nor do they breathe through their mouths. Instead, they have a system of tiny tubes, called tra- cheae, through which oxygen diffuses into their bodies. The tracheae begin at the surface of an insect's body and penetrate into the interior. Suppose that a trachea is 1.9 mm long with a cross-sectional area of 2.1 × 10-º m². The concentration of oxygen in the air outside the insect is 0.28 kg/m², and the diffusion constant is 1.1 × 10-5 m²/s. If the mass per second of oxygen diffusing through a trachea is 1.7 X 10-12 kg/s, find the oxygen concentra- tion at the interior end of the tube.arrow_forward1.

If each bacterium is 5µm × 5µm × 20µm in size, find the number of bacteria if their total mass is 30 grams. Recall that 1µm = 10−6 meters. b. Suppose that you learn that the sizes of bacteria range from 4µm × 5µm × 15µmto5µm × 6µm × 25µm. What is the range of the possible number of bacteria making up the total mass of 30 grams?arrow_forward
