    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 plate. In week three, the master plate was replicated onto three dropout plates: -His, -Leu, and -Lys. In the final week, the growth of the patches on the dropout plates were analyzed and class data was collected in order to conduct calculations for…

    Pill Bug Experiment

    • 4 Pages

    Purpose The purpose of this lab is to investigate animal behaviors by diving into the world of ethology. There are two ways pill bugs will respond to environmental stimuli: Kinesis (non-directional response) and taxis (directional response). Kinesis occurs when organisms (randomly) move around quickly when they’re unhappy and slowly when they’re happy, which is best demonstrated when one lifts up a rock or other material that the pill bugs are under. In contrast to the simpler response that does not necessarily involve many neurons, taxis is often observed in response to changes in light, heat, moisture, sound, and/or chemicals (odor).…

    Archeologists have found Ancient Egyptian calligraphy reading “let me live upon bread and barley of white ale made of grain red”. Bread and beer originated in the early history of mankind and played an essential role in Egyptian civilization. Historians estimate that bread stemmed from the Middle East approximately 10,000 years ago when pre-historic man accidentally hardened porridge after cooking it too long over an open fire. It formed a hard, flat, cracker-like substance. Flat bread became a crucial source of carbohydrates to supplement their diet and encouraged the farming of cereal grains.…

    Pill Bugs: An experiment Introduction Pill bugs are very small and can be found anywhere. Under rocks, in between cracks, in your science class; they are everywhere! However, it is common knowledge that pill bugs do not like to be in open spaces. There are just too many dangerous possibilities, and they don’t need to take the risks. In this experiment, we tested to see if light affected the decisions of where pill bugs like to stay.…

    Introduction: Leaf Disk float in water alone. When a solution consisting of a small amount of sodium bicarbonate is added to the water it causes the leaf disk to sink. As photosynthesis continues in the leaf disk it releases oxygen and causes the leaf disk to rise. While cellular respiration is occurring also the rate that the disk raise is an in implicit measurement of the net rate of photosynthesis. The independent variable in this lab is the solution and the light because it can be controlled.…

    Radish Seed Experiment

    • 6 Pages

    Abstract This experiment is about the effect of microwave radiation exposure on the percent that radish seeds germinate. The hypothesis in this experiment is if the radish seed is placed in the microwave for 8 minutes, then the percent of germinated seeds would be the lowest out of all the times. This experiment is important because if something happens and radish seeds are exposed to microwave radiation people would be able to know if the radishes would germinate if they knew the time they were exposed. This could also be used to find out if people could grow radishes in space because there is a lot of microwave radiation.…

    Determining The Process of Photosynthesis And Cellular Respiration Using Elodea and Yeast Introduction Photosynthesis is an essential process to life on earth, in which plants and other organisms use sunlight to create food from oxygen, and carbon dioxide. Cellular respiration is when energy in food is released and converted to ATP, which is then used as chemical energy to complete tasks within a cell. This process usually requires oxygen and releases carbon dioxide. Photosynthesis and cellular respiration are similar in some areas and different in others. The purpose of both of the process is to produce energy, but they have different ways of achieving this goal.…
