Calcium is an extremely important factor for health and longevity. It serves both a structural and physiological role in the entire organism. Bones are constantly breaking down and rebuilding‚ and calcium is directly involved in this process. Calcium ions (Ca2+) are essential mediators of a wide variety of cellular activities‚ including the passing of information along neurons and between adjacent neurons. Hormonal regulation is also mediated by the proper functions of calcium and calcium ions

embryonated broiler chicken eggs. Group A is negative control with no haemagglutination activity and group B as positive control with positive Haemagglutination activity. For each drug to be tested‚ 40 eggs were assigned to 8 groups (i.e. A‚ B‚ C1‚ C2‚ C3‚ D1‚ D2‚ D3) with 5 eggs in each group. Embryonated eggs in each of C1‚ C2 and C3 subgroups were treated only with 3 different concentrations of each compound to evaluate toxicity respectively. Whereas embryonated eggs of SUBGROUPS D1‚ D2 and

Abstract The purpose of this lab was to study the composition of hydrates. Hydrates are ionic compounds that are chemical compositions made of water and salt. A main objective was to remove water from the hydrate by heating‚ and determine the amount of water that was in the hydrate. After doing this‚ one had to predict the empirical formula for hydrated copper sulfate. In doing this lab‚ one was able to see the gradual change in the composition of a hydrate into an anhydrous salt. The lab was

ABSTRACT By calculating the difference in the mass of the hydrate copper (II) sulfate and the anhydride we were able to determine the mass of water in the hydrate. This information was then used to determine the empirical formula of the hydrate‚ defined as a compound formed by the addition of water to another molecule. In the first trial‚ the mass of water in the hydrate was determined to be 0.41 g‚ while in the second trial the mass of water was 0.52 g. Moles of water associated with a single

Egg flotation Objective/Question/Problem My objective is to see which egg will float. The question is how much salt is needed to be added to make the egg float. The problem is that I do not know how much salt is needed to make an egg float. Hypothesis If I add salt to the water then the egg will float because the egg has a density that is lower that the density of the fluid it displaces. Background Information If the object has a density that is higher than
