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 What is cholesterol? Cholesterol‚ a waxy substance produced by the liver and found in certain foods‚ is needed to make vitamin D and some hormones‚ build cell walls‚ and create bile salts that help you digest fat. our liver produces about 1‚000 milligrams of cholesterol a day‚ enough cholesterol for the body to be ok without food with colesterol but it’s hard to avoid cholesterol entirely because so many foods contain it. Consequences o high cholesterol. Too much cholesterol in the

Biology revision -keeping healthy Diet and Exercise What should a balanced diet include? Carbohydrates‚proteins‚fats‚vitamins‚minerals‚fibre‚water. Don’t get enough of these? Become malnourished. How much energy do we need? The energy you need depends on various things : 1. Gender- Males need more energy then females‚ Bigger size‚ have a bigger ratio of muscle to fat than women. 2. Age- Young people are still growing‚ they are reproducing and are more active (exercise) than old people

Bacterial Biology █ BRIAN D. HOYLE An understanding of the fundamentals of bacterial biology is critical to bacteriologists and other forensic investigators attempting to identify potential biogenic pathogens that may be exploited as agents in biological warfare or by bioterrorists. Fundamentals of Bacterial Biology Bacteria are one-celled prokaryotic organisms that lack a true nucleus (i.e.‚ a nucleus defined by a membrane). Bacteria maintain their genetic material‚ deoxyribonucleic

Biology project Measuring Light Intensity Soil moisture and soil pH meters are also available - both are used by simply pushing the probe into the soil and reading themeter. Errors can be made when measuring abiotic factors when the soil moisture or pH meter probes are not cleaned between readings. As always the results can be made more reliable by taking many samples. Here are some examples: Daisies The more light available‚ the more daisy plants will be present.0 This is because daisies

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

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 them. What is the purpose of soaking the Petri dishes in bleach? What are the cell walls
