The vacuoles are the membranous sacs which are filled with fluid. These spaces inside the vacuoles are free of the cytoplasm and are lined by the membrane. These vacuoles serve the purpose of storage, digestion, ingestion, and excretion. The vacuoles allow the plant cells to attain big size without the accumulation of the bulk.
The vacuoles are present in both plant and the animal cells, however, their size in plant cells is larger. No proteins or microtubules composes these vacuoles.
Hence, the blank can be filled with 'membranous sacs'.

Aldosterone hormone would be released in high quantities
when the electrolyte balance in the body is low. This would enable the sodium
ions to be reabsorbed from the glomerular filtrate by the nephrons’ tubules.
ADH (Anti-duretic hormone), on the other hand, would be released in high amounts
if the electrolyte concentration in the body is high. This would enable the
high re-absorption of water from the glomerular filtrate.
