Answer:
Because each subject in an experiment has to have equal conditions to ensure the most accurate results. And water temperature is known to impact plant growth. An experiment using different water temperatures is a terribly inaccurate experiment.
Answer:
Vacuum
Explanation:
A vacuum is usually defined as a space in which there is an absence of matter. It can also be said that there is an extremely low amount of pressure due to which the particles present in it are not affected by any type of process that occurs in space. The value of pressure is lower than the value of normal atmospheric pressure.
For example, sound cannot travel in space because there is no medium such as water and air through which the sound waves can propagate.
Because during digestion, blood is needed to execute the process.
Swimming also requires blood so it takes the blood that was initially being used for digestion away.

Bacteria, archaea, plants, protists, animals, and fungi, can use cellular respiration.
And the main ones that use celluar respiration are autotrophs and heterotrophs.
Hope I helped you out (:
