Answer:
Spirometry is a type of pulmonary function test (PFT), a noninvasive procedure that provides important information about how well the lungs are working. More specifically, it reveals how much air is moving through the lungs and how quickly as you breathe through a tube.

Biologists who work in the fields of genomics and molecular biology study DNA genome content and analyze genetics on a molecular level. They do it to map DNA and use it to prevent diseases or anything similar.
Answer:
The neurons interact with each other at synapse through action potential generated in response to the stimulus. At the resting phase, all the ion channels remain closed and the cell maintains a high amount of Na⁺ ions outside the cell and a high amount of K⁺ ions inside the cell. This difference maintains the membrane potential at -70mv.
When a stimulus activates a cell receptor, it causes the opening of the sodium channels in response to either mechanical stimulus or neurotransmitter released due to stimulus. The opening of the sodium channels leads to the influx of Na⁺ ions which changes the potential from -70 mv to more positive value. When this change in membrane potential reaches - 55 mv it leads to the opening of the voltage-gated channels which causes an influx of Na⁺ ions. This more influx of Na⁺ ions leads to depolarization when the membrane reaches above the threshold and the action potential is generated in the neuron.
