As John is testing the effect of temperature on the solubility of sugar in water. To test this, he will measure the amount of sugar dissolved at different temperature level.
Answer:
<em>Thermotoga maritima</em> is a bacterium that have similar genes of most of the archaea that live in similar extreme environment is most likely the result of lateral gene transfer.
Explanation:
This bacteria contain certain genes that are extremely similar with the genes that are present in archaea. This is a example of lateral gene transfer where acquisition of genetic material takes place by another organism without being it's offspring.
Prokaryotes can exchange genes under highly selective condition through lateral gene transfer that enters in to the body of diverse bacteria where the genes involve in several functions like metabolic function, transport of energy transcription, gene regulation etc.
The independent variable is that in which the result is dependent on. For experiments, this is usually the item being varied. For this case, what is being varied is that one group is given caffeine while the other is not. That makes the amount of caffeine given to be our independent variable.
