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

Biology coursework The aim of this experiment is to investigate the affect of pH on the enzyme amylase. The amylase is used to break down the polysaccharide starch. Amylase is a digestive enzyme classified as a saccharidase (an enzyme that cleaves polysaccharides). It is mainly a constituent of pancreatic juice and saliva‚ needed for the breakdown of long-chain carbohydrates (such as starch) into smaller units. Amylase is also synthesized in the fruit of many plants during ripening‚ causing them

Heredity is the tendency for traits to be passed from parent to offspring. 3. Why did Gregor Mendel choose garden peas to student for his experiments? Mendel chose to work with the garden pea because several of its characteristics made it easy to work with: many varieties were available‚ he knew

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 effect of water and fertilizer on corn seedlings Biology 1108 Lab Section November 7‚ 2012 Abstract The effect of water and fertilizer on corn seedlings was examined. It was hypothesized before the experiment that enough water with sunlight and air should make the plants grow healthy. It has to do with photosynthesis. Fertilizer is also going to make the plants grow much faster; this is because of the nutrients in it. The experiment took about four to six weeks to complete; it took some

Aim: The aim of the experiment that was carried out was to see‚ at what temperature and in which standard solution‚ does the amount of dye left in the boiling tube had the highest percentage transmission. Beetroot was used for the experiment because it was easier to see the dye after the practical was completed. Putting beetroot cylinders into different boiling tubes‚ which contained
