9.16 Explain why human skin coloration is not sufficiently explained by polygenic inheritance. -Polygenic inheritance is the additive effects of two or more genes on a single phenotypic characteristic. 9.17 Describe the limits‚ benefits‚ and ethical challenges of genetic testing. -Genetic testing can fall into one of the five categories: carrier testing‚ diagnostic testing‚ prenatal testing‚ newborn screening‚ and predictive testing. Carrier testing is designed to determine whether a person

There are many differences between photosynthesis and cellular respiration. Photosynthesis requires energy as photons. Cellular respiration supplies energy in the form of ATP. In photosynthesis‚ electron transport occurs in the membranes of chloroplasts or thylakoid discs. Cellular respiration takes place in the membranes of mitochondria. In photosynthesis‚ water breaks down to supply 2 electrons and 2 Hydrogen ions and release ½ O at the beginning of the chain. In cellular respiration‚ 2 electrons

Aerobic Respiration Breaking down glucose to release energy Products are Carbon dioxide and water Diffusion is … the movement of molecules from a region of high concentration to a low concentration until the concentration is equal. Role of a human circulatory system: Diffuse In – oxygen (O2)‚ dissolved food (glucose) and water (H2O) Diffuse Out – carbon dioxide (CO2)‚waste and water(H2O) Respiration – releasing energy in cells Breathing – getting air into and out of your body

Acid Rain Done By: Francis Lolas Teacher: Christine Due Date: 19/9/2012 Grade: 10 MYP 5 A There are many possible solutions to the problem that we are facing nowadays that is Acid Rain. Acid rain is formed from two main gases that are released in the atmosphere which are sulphur oxide and nitrogen oxide. I will talk later about the solutions for acid rain and the effect of this rain and what are the two forms of acid deposition. I have also watched some videos about acid

IODINE TEST FOR STARCH The Iodine test is used to test for the presence of starch. Iodine solution — iodine dissolved in an aqueous solution of potassium iodide — reacts with the starch producing a purple black color. The colour can be detected visually with concentrations of iodine as low as 0.00002M at 20°C. However the intensity of the colour decreases with increasing temperature and with the presence of water-miscible‚ organic solvents such as ethanol. Also the test cannot be done at very low

Origins of the Name The word‚ Aluminium originates from the ancient Latin word for alum‚ alumen‚ which is potassium aluminum sulfate‚ meaning “bitter salt”. We pronounce the element of aluminium’s name as follows‚ al-yuh-min-ee-uhm‚ which conforms to the IUPAC pronunciation of the word‚ with the regular ‘ium’ ending of majority of the elements of the periodic table. The History Aluminium was first discovered in 1825‚ by early discoverer‚ Hans Christian Oersted in Denmark. Before this time‚ alum
