• A. pH of urine is around 8.
• B. On an average, $75-80$ mg of urea is excreted via urine per day.
• C. Presence of ketone bodies in urine is a n indicator of diabetes mellitus.
• D. Relaxation of smooth muscles of the bladder and simultaneous contraction of urethral sphincter causes the release of urine.

Answer 1

The correct option is C Presence of ketone bodies in urine is a n indicator of diabetes mellitus.

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, the 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 the release of urine.

So the correct answer is 'Presence of ketone bodies in urine is an indicator of diabetes mellitus.'.
