Changes in Extracellular Fluid(ECF) osmolarity and volume

[ch5112]

I'm confusing whether ECF osmolarity and volume increases, decreases or no change for each treatment.

1/ Water Load- Osmolarity decreases and volume increases
2/ Water Load+ADH- Osmolarity increases and volume increases
3/ Water Load+Exercise- Osmolarity increases and volume has no change
4/ Isotonic Sports Drink(containing glucose&electrolytes)
- osmolarity has no change and volume increases
5/ Water load+Alcohol- osmolarity increases and volume increases


These are my answers shown above.
I'm confused with 2,3,4,5. Can any experts help me correct answers and getting me right understanding?


Also, if I am planning to do experiments on each treatment, can anyone suggest an appropriate control for each with explanation?

Thank you

in advance.1/ Water Load- Osmolarity decreases and volume increases. Control: A control should be set up with no water load and compare the osmolarity and volume to the water load results. 2/ Water Load+ADH- Osmolarity increases and volume increases. Control: A control should be set up with no ADH to compare the osmolarity and volume of the water load with ADH to the water load without ADH.3/ Water Load+Exercise- Osmolarity increases and volume has no change. Control: A control should be set up with no exercise to compare the osmolarity and volume of the water load with exercise to the water load without exercise.4/ Isotonic Sports Drink (containing glucose & electrolytes)- Osmolarity has no change and volume increases. Control: A control should be set up with no sports drink to compare the osmolarity and volume of the isotonic sports drink to the results without the sports drink. 5/ Water load+Alcohol- Osmolarity increases and volume increases. Control: A control should be set up with no alcohol to compare the osmolarity and volume of the water load with alcohol to the water load without alcohol.
