The process occurring at the sensory receptors that converts physical energy into coded neural activity that the nervous system

Anika [276]

Answer:

Sensory transduction

Explanation:

The sensory process involves many steps to send the signals from the receptor to the brain.

In this, the step that is involved in the conversion of the physical energy into the electrical signal at the sensory receptor (in the given case mechanoreceptors) is known as the Sensory transduction.

When the mechanoreceptors get stimulus by the physical force, it opens the mechanical gate of the dendrites which allows the influx of the positive ions. The influx of the positive ions causes depolarization of the membrane which initiates the action potential which is then transmitted to the brain.

Thus, Sensory transduction is the correct answer.

Volume is defined as the amount of mass that an object has? True or false

maria [59]

Answer:

False

Explanation:

Mass and volume are two different quantities. In fact:

- Mass is a scalar quantity representing the "amount of matter" contained in a certain substance. It is measured in kilograms (kg), which is one of the 7 fundamental SI units.

- Volume is a scalar quantity representing the amount of "three-dimensional space" occupied by an object or a substance. It is measured in cubic meters ( $m^3$ ).

Therefore, mass and volume are two different quantities. They are related through another quantity called density, given by:

$d=\frac{m}{V}$

where

m is the mass

V is the volume

So the density of a substance represents the amount of mass contained in a certain volume of the substance.
