It is through biopsychological feedback.

A class of chemical called a neurotransmitter is important in the transmission of nerve impulses. Neurotransmitters are packaged by the cell into small, membrane-bound sacs called vesicles. Upon receiving a chemical signal, the vesicles move toward the cell membrane and fuse with it, releasing the enclosed neurotransmitters from the terminal end of the nerve cell.

Avogadro's law states that: A. The volume of a fixed amount of gas is directly proportional to its temperature in Kelvin at cons

Travka [436]

Answer:

C. Equal amounts of gases occupy the same volume at constant temperature and pressure.

Explanation:

As we know by ideal gas law that

$PV = nRT$

now here we have

$V = \frac{RT}{P} n$

so as per Avagadro law if the temperature and pressure of the gas is constant then volume of the gas is directly proportional to the number of moles of the gas.

so correct answer will be given as

C. Equal amounts of gases occupy the same volume at constant temperature and pressure.

8090 [49]

Answer:

The new radius of the trajectory of the particle is four times the previous radius

Explanation:

In order to know what is the radius of the trajectory of the charged particle, if its speed is four times as fast, you take into account the following formula, which describes the radius of a charged particle in a magnetic field:

$r=\frac{mv}{qB}$ (1)
