Answer: The two different neutral isotopes of same element will have Atomic Number in common.
Explanation:
Isotopes are defined as the species which have same atomic number but different atomic mass. For example: are the isotopes of same element carbon having different atomic mass.
General form to write an isotope:
where, A = Atomic mass of the element
Z = Atomic number of the element
X = Element
As, the value of A is different for two isotopes and Z is same, so two different neutral isotopes of the same element have Atomic Number in common.
It may be due to the fact that there was an event that eliminated many of the individuals in species.

Answer:
Priestly observed that adding a plant to the jar caused the candle to stay lit longer.
Priestly himself inferred that plants gave off oxygen during photosynthesis, it provided the oxygen that was needed for the candle to be able to burn.
Answer:
Joseph Priestly observed that a candle alone in a jar did not stay lit for long and eventually went out and that when he added a plant to the jar, it caused the candle to stay lit longer and the plant to stay alive longer. Priestly then inferred that plants give off oxygen during photosynthesis, providing the oxygen needed for the candle to burn and that the burning candle gave off carbon dioxide, which was used by the plant.
