1. Why are there two of each chromosome in a normal karyotype? Answer: There are two of each chromosome in a normal karyotype because you Receive one from your mother and from your father. 2. Why are the consequences of chromosomal alterations referred to as “syndromes” and not diseases? Answer: The consequences of chromosomal alterations are referred to as syndromes and not diseases because you do not catch them and there aren’t contagious.

Prof. David B. Henthorn September 25‚ 2012 Summary The goal of this project was to determine the pre-exponential factor‚ k o ‚ the activation energy‚ E‚ and the reaction rate constants‚ k‚ of the saponification process of ethyl acetate using sodium hydroxide (NaOH) at 5 temperature between 15 and 25 degrees Celsius. Two trails were performed at temperatures 16‚ 18‚ 20‚ 22‚ and 24 degrees Celsius. The main equipment of the project were the jacketed beaker batch reactor and the LabPro conductivity probe

Scientific Background: Vinegar is an acid and there fore can be neutralised by an alkali. Acid + Alkali à salt + water Hydrochloric acid + Sodium Hydroxide à Sodium chloride + water Vinegar is a weak acid and therefore it only partially ionises in solution. CH3COOH ßà CH3COO- + H+ An alkali such as Sodium Hydroxide has a formula NaOH. If the alkali is strong then it ionises fully in solution. NaOH ßà Na+ + OH- When the acid H+ reacts with the alkali OH- the solution

Calcium oxalate (CaOx) being a major inorganic constituent of human kidney stones‚ contributes around 70-80% of the kidney stone. In India‚ approximately 5-7 million patients are suffering from kidney stone disease [6] (Kaladhar et al.‚ 2012). Urinary oxalate is found to be a major factor for calcium oxalate stone formation. As the molar ratio of oxalate-to-calcium is normally 1:10‚ slight changes in urinary oxalate concentration may

Question 2 3) Calcium in the diet of a teenager is actively absorbed in the small intestine and transferred into the intestinal capillaries. Describe the route this calcium would follow to end up in the upper arm. Describe in detail the role of calcium at the neuromuscular junction as well as its role in the mechanism of muscle contraction and relaxation of the triceps. Considering the function of calcium in bone growth‚ explain in detail how the humerus would grow in length. Calcium in the diet

of barium and calcium chloride‚ then the highest concentration of calcium chloride would affect them the most because of the production of hydrochloric acid and calcium oxide from the mixing of water and calcium chloride‚ two very dangerous acids‚ with the highest concentration having the biggest chemical reaction. Within five minutes of putting the Daphnia into the 10 (ppt) solution of calcium chloride‚ one or more of the Daphnia died. The Daphnia in the 1 (ppt) solution of calcium chloride died

In this experiment I will investigate the temperature of 50cm³ of water before and after I have added calcium chloride‚ I will gradually increase the amount of calcium chloride by 1 gram to see if there is a significant change. When Calcium Chloride is mixed with water it performs an exothermic reaction which makes new bonds between the salt (Calcium Chloride) and the water. This will therefore make the solution of the reaction increase in temperature. Exothermic reactions transfer energy
