As an animal grows, its surface area increases as a _____ function, while its volume increases as a _______ function.

A.       Cubic, cubic

B.       Cubic, square

C.       Square, cubic

D.       Square, square

1.Chicks receive antibodies from their mother through the __________ (be specific)

Explanation / Answer

It is known that an increase in CO2 causes an increase in the ventilation where the increase in pH thrashes out carbon dioxide which results in increasing the pH

B. increases CO2 is the answer

It is known that the surface to the volume ratio gets smaller as the cell grows and this restricts the cell from growing further larger.

Therefore surface area growth will be less when compared to that of volume.

Therefore surface area increases with square and volume increases with cubic

C. Square, cubic is the answer

1. Chicks receive antibodies from their mother through the egg where the antibodies are appeared on 12th day of incubation
