<span>Interstitial fibrosis and glomeruli tubular atrophy are pathological effects of hypertension on kidneys. This is especially as a result of hyalinization that results in sclerosis to the glomeruli which may ultimately lead to kidney failure if unmanaged. The hyaline accumulate in the nephron tubules resulting in protein in urine. The plaque build up in the kidneys, as a result, causes glomerular ischemia </span>
During colonoscopy, a flexible Fiberoptic or video colonoscope is used to visualize, examine and photograph the large intestine including the anus, the rectum and the sigmoid, transverse and ascending colon. This procedure is most frequently used for cancer screening and for surveillance in patients with previous colon cancer or polyps. In addition, tissue biopsies can be obtained as needed and polyps can be removed and evaluated. Other uses of colonoscopy include the evaluation of patients with diarrhea of unknown cause, occult bleeding, or anemia; further study of abnormalities detected after a barium enema and diagnosis clarification and determination of the extent of inflammatory or other bowel disease. Colonoscopy is contraindicated if the patient has a suspected or documented colon perforation, acute severe diverticulitis or fulminant colitis.
Answer:
First, second, and last are correct statements.
For accuracy and reliability of any experiment, a number of observations must be as large as possible. It reduces the effect of any observation or any event which might have happened by chance or error.
Thus, finches were better to record observations as they were available in large number as compared to the tortoise.
In addition, the life cycle of birds is smaller as compared to the tortoise which enabled the scientists to observe more generations.
Lastly, the birds were easy to capture and track as compared to the tortoise. Tortoise being an amphibian could live on land as well as in water which made it difficult to track them.
