Answer:
Simile
Explanation:
Metaphors are like similes but do not use like or as
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.
Answer: C) genetic diversity
Explainiton : Crossing over is essential for the normal segregation of chromosomes during meiosis. Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.
2) cell-tissue-organ-organ system
