What else can I help you with?
Which structure is used most directly by all protist for the process of excretion?
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 or false Obligatory water reabsorption involves the movement of water along an osmotic gradient?
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?
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.
What is the role of the skin in excretion?
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.
What is the difference between osmoregulation and excretion?
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 if water that must be excreted by the body to dispose of its wastes is termed?
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.
A drug that promotes water excretion?
Diuretic.
Water excretion is regulated by the?
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.
What is obligatory water reabsorption?
the reabsorption of water from pct,alh in nephron which is not influenced by adh.
What is the advantage of ammonotelic excretion over uricotelic excretion?
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.
What is the excretion of the kakapo?
it optain air by when it goes over water
What is obligatory reabsorption?
the reabsorption of water from pct,alh in nephron which is not influenced by adh.
Depletion of body fluid that results when water excretion exceeds water intake is called?
dehydration
Why water is yellow when you urine out it?
Due to excretion of urochrome, a blood pigment.
What does a contractile vacuole do for an organism?
It involve in excretion. It removes extra water
What are obligatory points of road?
obligatory points digram
A sentence for obligatory?
It is obligatory for us to attend school.
