the following occur? Calvin cycle‚ glycolysis‚ Kreb’s cycle‚ electron transport chain. Students in a biology class tested the effects of antibiotics on the growth of bacteria. They cultured bacteria in four glass Petri dishes and then added different amounts of antibiotic to each dish. After the experiment is completed‚ what should be done with the Petri dishes? After an experiment in which students cultured live bacteria‚ they soaked their Petri dishes in bleach before washing and reusing

Introduction Last week‚ my Biology class and I went down to the Port Kembla Rock Platform. While we were there we surveyed five different sectors about the rock platform and recorded them‚ these included: 1. Surveying the abiotic characteristics of the rock platform 2. Observing the abundance and distribution of the Black Periwinkle (Nerita Atramentosa) 3. Observing the feeding relationships and food webs of the organisms 4. Finding the adaption’s of organisms 5. And Observing the human impacts

Biology Notes 1.02 Sometimes a practice or belief claims to be science but does not follow the scientific method or cannot be proven reliable through experimentation. These practices are examples of pseudoscience‚ which literally means "fake science." Charms‚ astrology = stars‚ and phrenology= reading the bump on skull 1.03 * In the mid 1600s in the Netherlands‚ the scientist Antonie van Leeuwenhoek developed the first known microscope using a single magnifying lens. He was the first person

Biology coursework: Substrate specificity in yeast AIM: To find out which substrate (glucose‚ starch‚ maltose‚ sucrose or lactose)‚ does yeast‚ the organism containing the enzyme‚ breaks down the quickest. Introduction: Usually‚ every enzyme has a specific substrate that is what we call the “lock and key” theory. We can try the reaction of an enzyme with different substrates and this enzyme will just work well with one of those substrates. One type of reaction catalyzed by enzymes is anaerobic respiration

The reason for the experiment is to see which color from the light spectrum causes plants to grow faster. The prediction was that read light would cause the most growth in plants and that blue light would result in slower growth. The results did not support the hypothesis. Referring to table‚ one can see that blue caused both the spinach and radish plant to grow the most and that green light cause the plants to grow less. Spinach is a long-day plant therefore it was able to grow better under a constant

first to recognise genes are carried on chromosomes: the basis for modern genetics. He demonstrated the existence of sex-linked genes and expanded trait linkage using "crossing-over" 1911 Alfred Sturtevant‚ mapped the locations of several fruit fly genes. This was the first genetic map 1926 Thomas Hunt Morgan published the "theory of the gene" based on Mendelian genetics 1933 A new technique‚ electrophoresis‚ was introduced by Arne Tiselius for separating proteins in solution

Green‚ or common iguanas are among the most popular reptile pets in the United States. Iguanas are from the family called Iguanidae. This is a group of animals made up of lizards. In the wild iguanas are usually found in South American rain forests. They have also been seen in Central America‚ Puerto Rico‚ and Florida. Iguanas are herbivores‚ so they like to eat leaves‚ flowers‚ and types of fruit. Iguanas are diurnal‚ which means they are awake during the day‚ and they sleep at night. These reptiles

the effect caffeine has one ’s short term memory. The method used was a mixed design‚ a combination of the repeated measures and independent measures designs. The participants used were chosen from a sample opportunity‚ and all were twelfth grade Biology students. The results indicate that the lowest average score was that of the experimental group‚ after they ingested caffeine. The conclusion made is that I was unable to replicate the results of Koppelstatter‚ Mitchell‚ or Womble and Lesk. My

the salt concentration deprives the moisture and water from the roots. Through the roots and the cells of the grass and the plants being robbed of the water‚ the results are irreversible death of the area of the grass and plants. To design the experiment I would design a walkway with a line of freshly grown grass and put ice on it then apply table salt or rock salt and watch how the secretion of the saltwater mixture affects the immediate grass that lines the area of the
