B) Gopal then measured the mass of the seed leaves as the seeds germinate.
The graph below shows how the mass of the seed leaves changes with time.
Mass of seed leaves
P
Time (day)
Which graph (P or Q) shows how the mass of seed leaves change with time
during germination? Explain your answer.​

Explanation:

The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.
