-Which of these lines represents the pattern of change in mass over that time?

Quizplus · Accepted Answer

Line B shows a gradual increase in mass over time, starting at around 1.5 grams and increasing to about 5 grams at hatching. This pattern is consistent with the expected growth of a developing bird embryo inside the egg. Lines A and C show more erratic patterns of change in mass, which are less likely to be related to the growth of the developing bird.
