sattari [20]3 years ago
5 0
Biogeochemical cycles are essential for life and important to the ecosystems because matter on earth is limited in amount, and space for dead organisms as well. Additionally, biogeochemical cycles are important as as they transport and store these chemical elements so that they can be used by living organisms.

Where does the waste material in the body come from and why does the body need to get rid of these waste materials?
Marizza181 [45]
"Waste" -- in the form of urine and feces -- how the body removes the parts of food we ingest that is not used for nutrition and also is a way to rid the body of toxins. The kidneys filter the blood, removing "waste" products such as excess vitamins or drugs (this is why your urine can have a bright color if you take high doses of vitamin c) and liquid waste is held in the bladder before being released. Food travels through the gut to be digested -- broken down into usable bits and waste. After breaking down in the stomach, the material travels through the small and large intestines. The small intestine is lined with villi -- tiny protrusions that add surface area so nutrients can be absorbed into the bloodstream. In the large intestine and colon, water is pulled from the mass so it becomes more solid. Eventually the solidified waste passed through the rectum and out the anus as feces. The build-up of waste in the body can itself be toxic -- if the kidneys do not function properly to clean the waste out, the buildup can be fatal. When the body goes into emergency mode to eliminate a toxic substance -- such as e. Coli in the case of food poisoning -- the intestines don't both absorbing water and the result is the liquid fecal matter being quickly passed through and ejected as diarrhea.

<h2>Calculate the Rf values</h2>

Explanation:

  • In the event that an alternate dissolvable were utilized, the Rf worth would not be the equivalent on the grounds that, contingent upon the dissolvable, there is a distinction in dissolvability. On the off chance that an alternate dissolvable was utilized, the general places of the groups would be different.
  • The Rf estimation of the xanthophyll is 66% that of carotene since xanthophyll has a H bond with cellulose, which backs it off, and makes it less dissolvable in the dissolvable.
  • Carotene is progressively dissolvable in 9:1 oil ether CH3)2CO arrangement, which made it be conveyed higher and have a bigger Rf value.
  • Measure the separation the dissolvable voyaged, which is Df, and measure the separation the test arrangement voyaged, which is Ds.
  • Ascertain the maintenance factor utilizing this condition <em>RF = Ds/Df. </em>
  • Basically isolate the separation the arrangement went by the separation the solvent traveled.
