Answer:
Gas.
Explanation:
Gas which is present makes the three bottles different from one another. There are three factors which is used for testing of cellular respiration such as amount of oxygen consumed during this process, amount of glucose used and amount of carbondioxide produced during cellular respiration. During cellular respiration, oxygen used in order to break down glucose and releases high amount of energy with the waste materials such as carbondioxide gas.
D, the theory has been built up with evidence over time.
It is important to go through a fluid phase as it is being produced because the object must go through heat to be melted and then it should be put into a mold to be formed. Also, it go though heat to keep it from cracking and go to be cooled and harden. Hope this answers the question. Have a nice day.
<span>High mass stars are the largest, hottest and brightest while the low mass stars are the smallest, coolest and dimmest. High mass stars use their hydrogen fuel rapidly and have short lives while the low mass stars use hydrogen fuel slowly and have long lives. High mass stars pass through the Red Supergiant stage before dying in supernovae explosions while the low mass stars simply die by burning up their fuel to leave behind the white dwarfs which themselves cool and contract further to black dwarfs.
