The correct answer is "a steroid hormone that reduces the amount of fluid excreted in the urine".
Aldosterone is a steroid hormone produced in the adrenal gland, whose main function is the homeostatic regulation of the blood pressure, plasma sodium, and plasma potassium levels.
Aldosterone's main mechanism of action is to regulate the reabsorption of sodium and excretion of potassium in the kidney, which in turn influences the retention of water and the volume and pressure of the blood. Based on all this, aldosterone reduces the amount of fluid excreted in the urine.
Scientists often perform experiments to check and recheck their work. They also redo these experiments to ensure correct results.
Cellular respiration is the process that cells use to break down food to use as an energy. Aerobic cellular respiration uses oxygen and yields many more ATP molecules than anaerobic cellular respiration, which does not use oxygen and yields only two ATP molecules.
The answer is isometric training. To simplify, the strength gains with isometric training are specific to the angle of muscle contraction. In addition, Isometric exercise or isometrics are a kind of strong physical activity in which the joint angle and muscle length do not alter throughout contraction likened to concentric or eccentric contractions or as called as dynamic or as isotonic activities.
