skin color are examples of polygenic inheritance‚ which does not follow a Mendelian pattern of inheritance. pleiotropy is the single gene controlling or influencing multiple (and possibly unrelated) phenotypic traits. Mutation in this type of gene will simultaneously affect more than one trait. An example is phenylketonuria‚ a human disease caused by mutation(s) in a single gene that codes for the enzyme‚ phenylalanine hydroxylase. The disease is characterized by mental retardation and reduced hair

this case the truss is termed statically overdeterminate. The SE 110.22 experimental set-up permits investigation and comparison of statically determinate and statically indeterminate trusses. Using the bars and node discs‚ a statically determinate‚ single plane truss is first constructed. On installation of a surplus bar the truss becomes overdeterminate. By way of a load application device‚ straight or inclined forces are applied to the truss‚ thereby simulating various load cases. The occurring tensile

1. OBJECTIVES (a) To determine the equivalent circuit parameters of a 3-phase squirrel-cage induction motor from laboratory test data. (b) To determine the performance characteristics of an induction motor under load conditions. (c) To control the no-load speed of an induction motor. 2. INTRODUCTION 2.1 Three-phase squirrel-cage induction motors An induction motor is a transformer with a rotating secondary winding. It has two essential components: an outer stationary stator and an

OLD COINS TURN TO GOLD DESIGN: Problem or Research Question: How does zinc effects the color change in a copper penny? Hypothesis: If copper and zinc comes together‚ then it will form brass‚ which gives gold color to copper penny. Variables: There were no variables at this experiment PROCEDURES: Materials: Zinc (SN) filling‚ 3M NaOH solution‚ Copper penny‚ tongs‚ Hot plate‚ 100 ml beaker‚ 250 ml beaker‚ Bunsen burner‚ Water‚ Spoon. Procedure: First‚ we turned on the hot plate.

Lauren Sullivan Plants Imperfections Abstract The purpose of this experiment was to plant different crosses and observe the different phenotypic ratios the plants present. The procedure of this experiment was plant six different crosses and water them correctly so that we could observe the different phenotypes and compare them to Mendel’s proposed ratios. Mendel‚ who had studied peas‚ did a similar experiment and came up with specific ratios that a monohybrid and dihybrid cross should show. His

Investigation Investigate the amount of heat evolved when magnesium reacts with dilute acids. Planning What I am going to do I am going to find out how much heat is given out when magnesium reacts with a variety of dilute acids. In order to make comparisons between the acids‚ I shall use my results to work out how much heat would be given out if 1 mole of magnesium reacted with an excess of each acid. The acids I shall use are hydrochloric acid‚ sulphuric acid‚ nitric acid and ethanoic acid

1. Start off by weighing two paracetamol tablets using some accurate scales. Record the mass down (1.15g). This had to be as accurate and precise as we could get it so we had the correct weight to start the experiment. Without this then the results we found at the end would not be accurate. A problem that could be faced with this is that the scales may not have been fully set to zero. Also it takes time for it to fully reach its weight on the reading so you may move them too quick before the right

The bone sample has been soaking in vinegar with a pH of about 3.0 for a little over a week. The exterior of the bone remained intact the entire time. Once I removed the bone‚ I realized that the interior integrity of the bone was compromised. Now that the bone was exposed to the acid for such a long period of time‚ it was more flexible. The reason the long bone became so bendable is because the bone is largely made up of calcium salts. The vinegar broke the calcium phosphate down‚ leaving only collagen

If the page to be removed has been modified while in memory‚ it must be rewritten to the disk to bring the disk copy up to date. If‚ however‚ the page has not been changed (e.g.‚ it contains program text)‚ the disk copy is already up to date‚ so no rewrite is needed. The page to be
