Which of the following answer choices describes the pattern of nutrition used by embryos of birds? Select one: a. Placentotrophy b. Heterotrophy c. Lecithotropy d. Materotrophy
Which of these is the correct explanation of mass change in developing eggs as illustrated in the graph? Select one: A. A is the correct representation of mass change because as the baby bird develops inside the egg, it grows new parts. B. 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 CO2. C. C is the correct representation showing that nothing new comes into the egg and nothing leaves the egg, so it retains the same mass.

Refer to the figure shown here. Which of the following would have been a selective agent or pressure that could lead to the reduction in hindlimbs through time? A) The animal's body size was too heavy to support the weight on land and hindlimbs were no longer useful. B) More emphasis was placed on flexing the backbone than on paddling with hindlimbs for swimming. C)Appendages cause resistance, or drag, when moving through water.
