Parathyroid glands is a negative or positive feed back?
The parathyroid glands are involved in negative feedback regulation of blood calcium levels. When blood calcium levels are low, the parathyroid glands release parathyroid hormone (PTH) to increase calcium levels by stimulating calcium release from bones, absorption from the intestines, and reabsorption from the kidneys. Once calcium levels are restored, the release of PTH is inhibited, demonstrating negative feedback control.
What is a feedback mechanism in the skeletal system?
A feedback mechanism in a the skeletal system includes the bone narrow allowing calcium level to increase
What is the positive and negative ions if calcium chloride?
The chemical formula of calcium chloride is CaCl2. CaCl2------------Ca2+ + 2Cl-
What is the positive and negative ion for calcium oxide?
The positive ion in calcium oxide is the calcium ion (Ca^2+), which has lost two electrons. The negative ion in calcium oxide is the oxide ion (O^2-), which has gained two electrons.
What is the definition of negative feedback?
(Biology) Mechanism of the homeostatic response by which the out put of a system suppresses or inhibits activity of the system: Eg- when a certain blood concentration of a hormone is reached, the endocrine gland releasing the hormone is inhibited by the presence of the hormone.feedback is often use in electronic ckt like amplifiers............feedback is process of sampling a part of the output{apmlified} signaland applying it back tothe input via network by using capacitors inductors etc but mostly resistors.........called feedback loop..it is of two types.....positive feedback and negative feedbach....in positive feedback output gain is increases as output signal is in ssame phase with input signal whereas in negative feedback output gain decreases as output signal is in opposite phase with input signal........
What parts of the calcium chloride are attracted to what parts of the water molecule?
The positive calcium ions in calcium chloride are attracted to the negative oxygen atom in the water molecule, while the negative chloride ions are attracted to the positive hydrogen atoms in the water molecule.
Is calcium oxide a positive or negative ion?
Calcium oxide is a compound composed of calcium (Ca) and oxygen (O) ions. Calcium has a 2+ charge, while oxygen has a 2- charge. Therefore, calcium oxide is made up of a positive calcium ion (Ca2+) and a negative oxide ion (O2-).
How does the regulation of blood calcium concentration exemplify negative feedback and homeostasis?
Calcitonin hormone lowers the blood calcium level. Parathormone or parathyroid hormone rise the calcium level. Vitamin D perform the some what complicated role. Together they maintain the calcium level almost precisely. This is not the precise and expert answer.
How do you write the positive ion and negative ion for CaS?
The positive ion for CaS is Ca^2+ (calcium ion) and the negative ion is S^2- (sulfide ion).
Is calcium the most abundant negative ion in extracellular fluid?
No, chloride is the most abundant negative ion in extracellular fluid, not calcium. Calcium is an important cation in the body and plays a role in various physiological processes, but it is not the most abundant negative ion in extracellular fluid.
How is the bonding in calcium oxide different from the bonding in sodium chloride?
calcium is mdonating one electron to each chloride. This makes the calcium a positive charge and the chloride a negative charge. This is called ionic bonding (CaCl2)
Does calcium form a negative ion?
No. There are no known compounds containing anionic calcium. Most of the compounds of Ca contain the Ca2+ positive charged ion.
