Answer:
Compressions and Rarefactions
<em>A vibrating tuning fork is capable of creating such a longitudinal wave. As the tines of the fork vibrate back and forth, they push on neighboring air particles. The forward motion of a tine pushes air molecules horizontally to the right and the backward retraction of the tine creates a low-pressure area allowing the air particles to move back to the left.</em>
Explanation:
These regions are known as compressions and rarefactions respectively. The compressions are regions of high air presure while the rarefactions are regions of low air pressure.
<em>Sound waves can also be shown in a standard x vs y graph, as shown here. This allows us to visualise and work with waves from a mathematical point of view. The resulting curves are known as the "waveform" (i.e. the form of the wave.) The wave shown here represents a constant tone at a set frequency.</em>
Answer:
this is how proteins are bound, through a series of amino acids combined in a chain
Explanation:
The correct answer is: A) GABA
GABA or γ-aminobutyric acid is a type of amino acid that's found in proteins. It is the main inhibitory neurotransmitter in the brain which means that GABA reduces neuronal excitability throughout the nervous system. GABA binds to its receptors that are located on the neuron’s plasma membrane. This binding causes the opening of ion channels that transport chloride ions into the cell or potassium ions out of the cell.
