The diagnostic term colo/scop/y literally means:

The term 'colo' means large intestine and the term 'scopy' means observing things with an instrument. Hence, the term coloscopy would mean the endoscopic observation of the large intestine. An CCD camera or a fibre-optic camera are the instruments that are used for this procedure. Coloscopy is generally termed as colonoscopy.

The method of colonoscopy is effective to diagnose a wide number of toxic diseases of the large intestine. Colon cancer can also be screened through this technique.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
