1. cytosine Dioxide is one of the substances carried in mammalian gunstock.
a) Why is it incumbent for nimiety carbon dioxide to be take from blood?

Carbon dioxide is a waste product and must be removed to maintain the normal pH balance of the blood. By removing excess carbon dioxide, it prevents a build up of carbonic vinegarish, which causes the dark of pH, and therefore increasing breathing rate and depth. Carbonic acid forms when carbon dioxide dissolves in pee. At normal levels, the carbon dioxide- hydrogen carbonate ion (HCO3-) equilibrium is an important mechanism for buffering the blood to maintain a constant pH.

b) In what forms is carbon dioxide transported in blood?

or so carbon dioxide enters the red bloods cells and is combined with water to form hydrogen carbonate ions (HCO3-). Some is attached to haemoglobin molecules in red blood cells and a small percentage is transported in plasma as dissolved CO2.

c) You preformed a firsthand investigation to demonstrate the exploit of dissolved carbon dioxide on pH water. Outline your method, identifying the variables and depict for how you ensured the reliability of your data.

Method:
1. Place hydrochloric acid in the sidearm run tobacco pipe.
2. Put in marble chips ( atomic number 20 carbonate).
3. Fill trial tube with linden tree water.
4.



Place sidearm in test tube full of limewater.
5. Observe.
6. Repeat steps 1 to 5, refilling lime water with distilled water.

Variables:
Independent Variable; Lime water, distilled water (H2O)
Dependent Variable; carbon dioxide (CO2)
Constant; the hydrochloric acid (HCl), calcium carbonate (CCO2)

Reliability:
The reliability of the experiment was made through with(predicate) repeating the experiment several times to make it much valid. Whilst doing that we also kept the amount of hydrochloric acid in the sidearm test tube, as well as the amount of lime water or distilled water in the test tube to a constant amount throughout the experiments. The reaction of the calcium carbonate with the...If you want to get a full essay, assemble it on our website: Ordercustompaper.com
