1.	Which one of the following is correct for a normal human?A. pH of urine is around 8B. On an average, 75-80 mg of urea is excreted via urine per day.C. Presence of ketone bodies in urine is an indicator of diabetes mellitusD. Relaxation of smooth muscles of bladder and simultaneous contraction of urethral sphincter causes release of urine.
Answer» Correct Answer - C In a person suffering from diabetes mellitus, degradation of fat increases resulting in the production of ketone bodies. These are acidic and poisonous and get excreted out in urine. Therefore, presence of ketone bodies in urine is an indicator of diabetes mellitus. pH of urine is 6. On an average, 25-30 gm of urea is excreted via urine daily. Contraction of smooth muscles of the bladder and simultaneous relaxation of the urethral sphincter causes release of urine.
