In the event of a chemical splash to the eyes, flood the eyes for at least 15-30 minutes with water. Flush from the eye outward. If you were not wearing proper eye wear, a chemical could splash into your eye and would make it necessary to use this. b. Fire Blanket (2 points)
Used in order to put out a small fire. If a small area of the lab caught fire, a fire blanket could be used to put it out. c. Shower (2 points)
Safety showers are designed to flood your body with water in the event of a fire or chemical spill. Stand under and activate the shower for at least 15-30 minutes. If a
Normal body temperature is 98.6°F. The student is not feeling well and only has a Celsius thermometer available. The student's temperature is taken and the thermometer reads 38.5°C. 1. Convert the temperature to Fahrenheit. (1 point)
101.3 F. 2. Is the student running a fever (i.e., is the normal body temperature above normal)? (1 point)
The student is running a fever. b. The student's cookbook says roast beef is rare at 140°F, medium at 160°F, and well done at 170°F. The student prefers beef cooked medium and only has a meat thermometer in °C. What temperature will the thermometer reach for the roast to be done the way the student likes it? (2 points)
71.1 C. c. The student is driving in Mexico and notices that daytime temperatures are only given in °C. The student sees a sign indicating that the current temperature is 29°C. What is the temperature in °F? (2 points)
84.2 F. 5. What is the purpose of the control group in the Scientific Method? Briefly explain and use examples. (5 points)
A control group is a reference group to which the second or experimental groups are compared. For example, you want to test whether temperature has an effect on runners. One runner is put on a treadmill in a heated room, one in a chilled room, and one at room temperature. The one at room temperature would be the control group which the others are compared against. 6. Design a (hypothetical) experiment that adheres to the Scientific Method. Be sure to

Diffusion and Osmosis Lab Introduction: 1) The relationship between the rate of diffusion, volume and surface area is that the surface area of a subject somewhat correlates with the volume of the object. When the surface area and volume are set up as a ratio, this gives a good idea as to how fast the rate of diffusion will be. The higher surface area to volume ratio, the faster the rate of diffusion. This is because then there is more surfaces to diffuse through and there materials to diffuse…

In the four-week long experiment conducted in the Bio 13 Lab, we were able to conduct a genetic analysis of the yeast S. cerevisiae, particularly investigating the inheritance and linkage of three genes: HIS4, LEU2, and LYS2. In week one, a suspension of spores was received and aliquots of the suspension were plates onto two YPD plates. After a week of yeast growth, haploid spore clones were carefully picked from the plates by sterile toothpicks and used to make patches on a new YPD plate, the master…

According to the lab manual, “an organisms’ metabolic rate is the total energy used by all of the cells” (Bio 112 Lab Manual, 2015). Animals, unlike plants, are not primary producers and thus require the consumption of others in order to obtain necessary energy. Such energy can be used in three major ways according to the lab manual: maintaining homeostasis, locomotion, or thermoregulation (Bio 112 Lab Manual, 2015). In order to assess such energy expenditure, it can be measured in two ways: directly…
