The main substance re-absorbed into the blood in the nephron are glucose, electrolytes (sodium, potassium, chloride) and water.
Almost all the glucose is reabsorbed at the proximal tubule of the nephron. Sodium, potassium and chloride are reabsorbed at the ascending loop of Henle, and water is reabsorbed at the descending loop of Henle.
Other nutrients that are reabsorbed are magnesium, phosphates, carboxylate, bicarbonate, amino acids, some urea, proteins and oligopeptides.
Reabsorption occurs in two steps namely active or passive extraction of sustances from the fluid in the tubules of the nephron, and into the interstitium , then transport of these substances from interstitium and into the bloodstream.
Adaptation is the process by which become suited to their environment
Are you referring to Murray Llewellyn Barr? :) He was the main scientist to experiment the neurons in female cats.
Hope this helps! :)
Answer:
Sister chromatids on the top and Chromosomes on bottom
Since frogs consume plants, it needs to have a longer small intestine so the food has more time to digest and be absorbed because the small intestine helps enthrall nutrients and calories from digested food, so it needs to be long enough so it can go through full digestion.
