The composition of urine is:Question 22Select one:a.variable (it changes).b.constant (it doesn't change).

Analysis of Urine Composition

The composition of urine can vary significantly depending on various factors such as diet, hydration levels, health status, and metabolic conditions.

1. Variable Nature: Urine composition is influenced by the intake of food and fluids, medications, and even the physiological state of the body (like hydration levels).

2. Factors Affecting Composition: For example, high protein intake can increase the levels of urea in urine, while dehydration can concentrate urine, affecting its composition.

3. Variation in Hormonal Influence: Hormones such as antidiuretic hormone (ADH) play a role in the concentration of urine, further emphasizing the variability.

Conclusion

Therefore, the answer to the question is:

a. variable (it changes).

Urine composition is not constant; it changes based on several factors as outlined above.
