respiration. Urea is produced in the liver from excess amino acids. Where are the substances excreted? Carbon dioxide is passed from the cells of respiring tissues into the blood stream. It is transported in the blood (mostly in the form of hydrogen carbonate ions) to the lung. In the lungs the carbon dioxide diffuses into the alveoli to be excreted as we breathe out. Urea is produced by breaking down excess amino acids in the liver. This process is known as deamination. The urea is then

Paragraph 1 In this paper‚ we take a look at the different phases of the Cs3H(SeO4)2 polymorphs. There are 3 different phases that is observed and each of them is influenced by the temperatures. In addition‚ in each phase‚ the polymorph exhibits different crystal structure. At the room temperature of 298K‚ it will be in phase 3 whereby it takes the structure of monoclinic-C2/m

Niels Bohr’s model of the hydrogen atom‚ was the primary reason for the understanding of energy levels.Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the diffraction patterns‚ scientists believed electrons could be described as waves. Bohr hypothesized that energy is being added to the hydrogen gas in the electricity form‚ and then leaving the gas in the form of light. He figured the light rays to be quantized‚ meaning only certain frequencies of
