Which of the following statements are true about toxicity? (6 points) a. If a toxin can be secreted in the distal convoluted tubule, then it has higher toxicity than a toxin that cannot be secreted [ Select] b. If a toxin is metabolized quickly, then it has lower toxicity than a toxin that cannot be metabolized quickly [Select] c. If a toxicant can be resorbed in the proximal convoluted tubule, then it has higher toxicity than a toxicant that cannot be resorbed [Select ]

Reabsorption in the nephron is a necessary step in urine formation, because filtration is non-specific and can lead to the loss of useful nutrients the filtrate in the Bowman's capsule does not contain useful nutrients, so the process of reabsorption helps to transport nutrients from the blood into the filtrate the body needs to actively excrete certain materials depending on the changing needs of the body filtration is specific and can lead to the loss of useful nutrients W 52°F A ch (9) 0
