An experimenter wants to observe the growth rate of radish seeds under different temperatures to see if it affects their growth rate. The
experimenter adds water to each seed and places them under several
different heating lamps. The length of their roots is measured every 6
hours. In this experiment the type of soil used is which variable?
A: control. B:Independent. C: Dependent. D: none of these

D, none of these.

Explanation:

The control group is going to be the radish seeds, they stay the same. The independent variable is the heating lamps and their temperatures. The dependent variable is the seed's growth rates.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

since there are no options posted i'll give you a few examples.
