What happened to the urine concentration as the solute concentration in the interstitial space was increased? how well did the results compare to your prediction?

The answer is that the urine concentration increased (became less dilute). This because of the increased electrolyte concentration in the blood. It causes the hypothalamus-pituitary gland to relead anti-diuretic hormone (ADH). This hormone increases the aquaporin 2 pore in the distal tubules and collecting tubules of the nephrons in the kidneys. Water is reabsorbed from urine hence making it more concentrated.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
