At dawn, all the phytochrome molecules present in the leaved are converted to the active Pfr form until sunset this is because the sun is unfiltered, and unfiltered sunlight has high percentage of red light, but lower far-red light, with the help of phytochrome system , the plants is able to compare the length of dark periods over several days.

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>
