The first experiment on the effects of acid rain germination of radish seeds, materials used were twenty radish seeds, , acid rain solution, pH strips, paper towels, two petri dishes, and tap water. The second experiment on testing the effects acid rain had on radish plant growth, the materials used were twelve radish seeds, six plastic cups, potting soil, two acid rain solutions (one with a pH of 3and one with a pH of five)…

short-term, small exposure to high temperature, and long-term, persistant exposure to constant high temperatures. The took populations of T. californicus from 11 pools at different latitudinal gradients in a local scale. They put the specimen in petri dishes with founding adult females. They only mate one time and store the sperm so they can produce many groups of offspring. To test if inbreeding could influence the patterns of thermal tolerance they crossed independent lineages of the same…

how will the color of light effect the germination of the radish seed? The experiment consisted of testing five germinating radish seeds under four different color lights, red, blue, green, and normal fluorescent light. The seeds were placed in a Petri dish covered in a wet paper towel and a piece of colored cellophane was also placed on top. The results were quite interesting because the seeds showed no difference in number of germination throughout the different light colors. Each color of…

The Medicine that Saved the World Penicillin is arguably the 21st century’s greatest invention ever. The miracle drug has saved millions of lives over the decades, that otherwise would have been ravaged by horrible diseases like pneumonia, syphilis, and gangrene. Penicillin also is thought to propel modern medicine into the lifesaver it is today. Penicillin is a weird drug, it is considered an antibiotic which mean the main purpose for the drug is bacterial diseases. Penicillin is thought to be…

Introduction The propose of this experiment was to see if we could conducted an experiment that we could elect data and act our hypothesis about sordaria. We hypothesized if tan and black sordaria got placed together to cross over, we could expect out of 50 sordarias that 27 would cross over and 23 would not cross over. Some research has brought up some discussion about how much tan or black sordaria is one the agar square to begin with. (Kitani 1961) If these numbers are more than the other,…

Among human beings are small microscopic life-forms that exist everywhere throughout the world. Those microscopic life forms are known as bacteria. Bacteria can survive in the coldest or hottest temperatures around the earth. Known to be unicellular, bacteria live within human bodies and also in the food we eat. Not only that, they are everywhere. Bacteria plays a major role in the human body. For an example, it is bacteria located in the intestines that help with food digestion. Even though…

hydrochloride and tetracycline phosphate complex. Tetracycline fluorescence has been used in studies of growing tumors and calcium deposition in developing bone and teeth. Dr.Okeke gave us more utilizes that were called piept, forceps, antibiotic disk, and petri dish. Piept is a slender tube attached to or incorporating a bulb, for transferring or measuring out small quantities of liquid, especially in a…

Our petri dish already had the agar prepared, so we didn’t have to go through the process of preparing this first. We grabbed cotton swabs and tried not to grab them from the ends to not get other bacteria on it. This could have been done differently though, we should have sterilized the cotton swabs to get best results. Then got the cotton swab to get my saliva and spread it across the agar and quickly closed the petri dish. Then we also grabbed the dog’s saliva…

prevent them from warming up. Observe and record how long it took the maggot to fully cross the outer circle. Place the tested maggot in the second petri dish, in order to differentiate which maggot have been used. Repeat the experiment with the remaining maggots. For testing the movements of Maggots under cool temperatures: Place the maggots in a Petri dish under the table lamp for 5 minutes. Place the sheet of paper on the Tripod stand so the circles are at the centre. Place the second table…
