Specific amino acids that line the selectivity filter of the K channel can dehydrate K and allow passage of that ion but cannot
Bogdan [553]

Answer:

Hi

True

Explanation:

Since on the inner and outer surfaces of the membrane, a series of negatively charged amino acids are found, which increase the local concentration of cations. The path of the ions begins on the inner surface filled with water molecules where the ion can retain its hydration sphere. Two thirds of its interior in the membrane the inside of the channel narrows in the region of the selectivity filter, forcing the ion to separate from the water molecules. Oxygen atoms in the selectivity filter replace the water molecules in the K+ hydration sphere, forming a series of coordination spheres through which the ion moves. The preferential stabilization of K+ against Na+ is the basis of the ion selectivity of this filter.

All of the following statements about solutions are correct Except?
Tasya [4]

Answer:

A solution is a heterogeneous mixture

Explanation:

This statement that a solution is a heterogeneous mixture is completely and totally wrong.

A solution is a homogeneous mixture.

Homogeneous mixtures have their constituents existing in just one phase.

  • It is a homogeneous mixture of solutes and solvents.
  • In a solution, the solutes particles are distributed uniformly in the solvent.
  • The solute is the substance that is dissolved to make the solution.
  • Solutes are usually present in a small amount than the solvent.
  • The solvent acts as the dispersing medium which allows the solute to go into the solution.
  • The solute can be solid, liquid or gas.

A student carries out this chemical reaction in a beaker:
nydimaria [60]

Answer:The correct answer is option (C).

Explanation:

Zn+CuCl_2\rightarrow Cu+ZnCl_2

After the reaction between Zinc and copper(II) chloride, Zinc chloride and copper will be obtained as a product. This reaction occurs because zinc is more reactive than copper which displaces the copper from its aqueous solution.

The student will expect to find copper metal at bottom of the beaker with aqueous solution of zinc chloride.

Hence the correct answer is option (C).
