Answer:
A change in pH can change the ionization of the side groups of basic and acidic amino acids of proteins., It is important to remember that these charges of are importance in stabilizing a protein secondary and tertiary structure and consequently affects its function. Changing these charges alters these interactions and disturbs protein loops such as beta-sheets and alpha-helices. This can change the structure of a proteins enzyme’s active site and cause it to fail to bind to a substrate or catalyze a reaction.

Answer:
Explanation:All cells in the body need to have oxygen and nutrients, and they need their wastes removed. These are the main roles of the circulatory system. The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.
Blood
Blood consists of:
Red blood cells – to carry oxygen
White blood cells – that make up part of the immune system
Platelets – needed for clotting
Plasma – blood cells, nutrients and wastes float in this liquid.

Explanation:
Percentage w/v means that weight of solute present in 100 ml of a solution. Hence, 15% w/v means that 15 gram of solute per 100 ml of solution.
Hence, for 2 L (or 2000 mL) preparation the amount of mass will be calculated as follows.

= 300 g
Thus, we can conclude that weight of Tris-HCL required is 300 g.
