The right answer is B

A radiotracer is an entity composed of a carrier molecule and a detectable radioactive isotope using devices such as gamma cameras or positron emission tomography.

A radiotracer is either a radioactive isotope alone or the combination of a molecule and a radioactive isotope. In this case, it is said that the molecule is labeled by the radioactive isotope.

A radioactive isotope is an atom whose nucleus, unstable, emits radiation. It could be :

- alpha radiation consisting of two protons and two neutrons.

- a beta radiation consisting of a negative electron (beta) or a positive electron (beta +, positron).

- a gamma radiation consisting of a high energy photon.

nadezda [96]

The type b intercalated cells will reduce the amount of bicarbonate ion secreted and the amount of hydrogen ions excreted by the body in order to deal with alkalosis.

<h3>What is alkalosis?</h3>

Alkalosis is a condition in which excess alkali is present in the blood.

Alkalosis occurs when the body exceeds excess alkali in from the body.

Therefore, the type b intercalated cells will reduce the amount of bicarbonate ions secreted and the amount of hydrogen ions excreted by the body in order to deal with alkalosis.

What will cause a decrease in market equilibrium price and an increase in equilibrium quantity? - an increase in supply - an inc
Fudgin [204]

Answer:

- an increase in supply

Explanation:

The interaction between the quantity demanded and the quantity supplied determines the price and the equilibrium quantity in a market economy. This is due to the rationality criteria of the economic agents (consumers will buy more quantities at the lowest possible price) and the law of supply and demand, according to which the excess / lack of products causes price decrease / increase and also an increase / decrease in quantity demanded. Thus, in order for the equilibrium price to decrease and the equilibrium quantity to increase, there must be an increase in supply, as there will be more products on the market, which will cause the price to fall. After the price drops, consumers will demand more. In this way, new price and quantity balance parameters will be determined.

How do the kidneys work to neutralize metabolic acidosis or alkalosis? If metabolic alkalosis exists, the kidneys slow their aci
melomori [17]

Answer:

Attaching letters to the options to make the question readable:

A. If metabolic alkalosis exists, the kidneys slow their acid excretion.

B. If metabolic alkalosis exists, the kidneys slow their acid retention.

C.  If metabolic acidosis exists, the kidneys slow their acid excretion.

D. If metabolic acidosis exists, the kidneys increase their acid retention

The correct answer to the question above is option A (If metabolic alkalosis exists, the kidneys slow their acid excretion.)

Explanation:

Metabolic acidosis is a condition where there is an alteration in the acid-base balance in the blood. Here, as the name implies, a high level of acid than necessary are found in the blood as a product of metabolism caused by an increase in acid production, failure of acid to be expelled in the kidney.  

Metabolic alkalosis is a condition where there is high level of alkaline in the blood than the body requires. Metabolic alkalosis occurs when the kidney is unable to excrete excessive alkaline in the blood and when there is too few acid-producing hydrogen ions present.

Kidneys fight metabolic acidosis by balancing acid levels in the blood by removing excessive acid in the blood through urine. It is also possible for the body to expel volatile acids through the lungs in the form of exhaled air.

Ways kidneys work to neutralize metabolic acidosis, ls If metabolic acidosis exists, the kidneys increase their acid excretion.

Ways kidneys work to neutralize metabolic alkalosis, is If metabolic alkalosis exists, the kidneys slow their acid excretion and increase their alkaline excretion or slow their alkaline retention.

How many grams of aluminum hydroxide are obtained from 16.2 g of aluminum sulfide?
nadezda [96]
Number of moles Aluminium sulfide
1 mole of sulfide contains 150 g
Therefore; 16.2/150 
               = 0.108 moles 
The mole ratio of Al2S3 : Al(OH)3 is 1:2
Therefore; moles of Aluminium hydroxide will be;
  = (0.108 × 2)
  = 0.216 moles 
But, 1 mole of  Al(OH)3 contains 77 g
Therefore, the mass of aluminium hydroxide is
   0.216 moles × 77
=  16.632 g
