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

FRQ #3 a) The flow of genetic information from DNA to protein in eukaryotic cells is called the central dogma of biology. The role of RNA in protein synthesis is extremely important as protein synthesis could not occur without RNA. Three forms of RNA exist solely to create proteins. Through a process known as translation‚ RNA constructs the proteins necessary to sustain life. Spliceosomes Process pre-mRNA by splicing out intronic nucleic acids producing mRNA which is then translated to protein

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

Charles Martin in Uganda: What to Do When a Manager Goes Native Q1) For a foreign company conducting business in Uganda‚ it was inevitable that Ugandan culture will largely affect the business operations of that foreign company. There are many cultural factors of Uganda which will have a large impact on the foreign company’s operations. One of the factors is “grease money” or a sort of a bribe‚ which was paid to accomplish something or speedup a task. Another attribute was their belief in the

Cycles in Biology Cycles in biology play a fundamental role in the world that we live in. Cycles occur all around and inside of us in many different forms‚ from the Krebs to the Calvin cycle. There are large scale cycles happening and they are essential in regulating the nutrients and substances that are around us which without‚ life on earth could no function. One of the largest cycles that occurs all around us is in everyday life is the carbon cycle. The current atmospheric
