Scenario Poultry Scientists Recorded Data to Help Maximize Farmers' Yields

Scenario
Poultry scientists recorded data to help maximize farmers' yields. They collected data about when in the life of eggs were laid by hens, how many eggs were laid by each hen in a particular age range, the weight of those eggs and the weight of the chicks that eventually hatched from those eggs. Examine the data table to answer the following questions
Egg and Chick Weight from Hens of Different Ages

-What is(are) the main factor(s) causing differences between the chick hatch weight and the weight of the egg when it is laid?

A) The only factor that causes the chick to weigh less than the egg when it is laid is the removal of the shell.
B) Not only does the chick have no shell, but it has lost some of its mass (weight) to the air during development.
C) During development in the egg, the chick embryo grows more cells so the weight increases.
D) Egg weight immediately after laying includes a lot of organic matter that evaporates during development.
