Answer:

The correct option is d. it causes exchange diffusion

Explanation:

Amphetamines are synthetic substances with a stimulating effect. Their action lies mainly in increasing synaptic levels of monoamines by various mechanisms, including diffusion exchange through membrane transporters. Amphetamine increases extracellular concentrations of serotonin by displacing the neurotransmitter from its specific presynaptic transporter. When amphetamine binds to serotonin transporters, on the one hand it prevents it from entering the terminal and on the other it reverses the recapture mechanism so that serotonin leaves the synaptic space.

Vlad [161]

Answer:

  1. <u>The hours are the independent variable.</u>
  2. <u>The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) .</u>
  3. <u>The domain is 0 to 30 </u>
  4. <u>The range is 0 to 330 </u>

Explanation:

<em>The hours are the independent variable and  should be plotted on the x-axis .</em>

<em>The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked )  and should be plotted on the y-axis </em>

<em>--------------- </em>

<em>Let +W+ = wages/wk earned </em>

<em></em>

<em>Let +h+ = hours/wk worked </em>

<em>The equation is: </em>

<em>+W+=+11h+ </em>

<em>The domain is 0 to 30 </em>

<em>( no hrs worked to 30 hrs worked ) </em>

<em>The range is 0 to 330 </em>

<em>( no wages eared to +11%2A30+=+330+ earned )</em>
