All protists use contractile vacuoles for the process of excretion. These organelles help regulate water balance by expelling excess water and waste products from the cell.
True. Obligatory water reabsorption in the kidneys involves the passive movement of water along an osmotic gradient, created by the active reabsorption of solutes like sodium. This process occurs mainly in the proximal convoluted tubule and the descending limb of the loop of Henle.
Excretion of dilute urine requires the reabsorption of water in the kidneys to concentrate the urine, as well as the regulation of hormone levels such as antidiuretic hormone (ADH) to control water reabsorption. This process helps maintain the body's water balance and avoid dehydration.
The skin plays a minor role in excretion by releasing small amounts of waste products such as salts and water through sweating. This process helps regulate body temperature and eliminate some toxins from the body. However, the main organs responsible for excretion are the kidneys, liver, and lungs.
Osmoregulation is the maintenance of the amounts of water and salts in body fluids. Excretion is a process of homeostasis. In this process,nthe metabolic wastes are eliminated from body to maintain the internal conditions at equilibrium.
The minimum amount of water that must be excreted by the body to dispose of its wastes is termed "obligatory water loss." This represents the minimal amount of water required to eliminate waste products, maintain electrolyte balance, and support normal physiological functions. The body's overall water balance is regulated by factors such as fluid intake, renal function, and hormonal control.
Diuretic.
Water excretion is regulated by the kidneys through a hormone called antidiuretic hormone (ADH), also known as vasopressin. ADH acts on the kidneys to increase water reabsorption, leading to concentrated urine and decreased water excretion. Other hormones, such as aldosterone and atrial natriuretic peptide (ANP), also play a role in regulating water excretion by affecting salt and water balance in the body.

The advantage is that ammonia (NH3) is not converted in Ammonotelic excretion. Fish can excrete ammonia through gills because there is a lot of water to dilute it in without causing damage to their cells. In Uricotelic excretion, NH3 has to be converted to a solid form via a complex and ATP-costly route. So Uricotelic excretion takes a lot more energy than Ammonotelic excretion.
