After reading the paragraph below, answer the questions that follow.
A student studying bird development recorded the mass of eggs from the time they were laid until the time they hatched in order to relate the mass of the egg to the final mass of the chick.
Which of these is the correct explanation of mass change in developing eggs as illustrated in the graph?
◦ A is the correct representation of mass change because as the baby bird develops inside the egg, it grows new parts.
◦ B is the correct representation of mass change because the baby bird uses cellular respiration to fuel the biosynthesis of new parts and gives off mass as CO
2.
◦ C is the correct representation showing that nothing new comes into the egg and nothing leaves the egg, so it retains the same mass.
