The parents of a new baby believe they brought the wrong child home from the hospital. Gel electrophoresis was performed using DNA samples from the parents and the child. A section of the gel electrophoresis results are shown in the diagram.
Which conclusion is valid based on the gel electrophoresis results?
Which conclusion is valid based on the gel electrophoresis results?
a)
They have the correct child, because her genetic information is identical to that of the father.
b)
They have the wrong child, because her genetic information does not match that of either parent.
c)
They have the correct child, because her genetic information came from both parents.
d)
They have the wrong child, because her genetic information matches only that of the mother.
17.
A team of ecologists observed feeding patterns of several populations in the desert. The energy pyramid shown below depicts the feeding patterns the ecologist observed. Which of the following best explains the difference in the amount of available energy in the trophic levels of the desert ecosystem?
a)
There is less energy available in the producers because their tissues are less dense than those at higher trophic levels.
b)
There is more energy available in the second trophic level because less energy is needed for hunting compared to the higher trophic levels.
c)
There is more available energy in the birds of prey because they have greater muscle mass for storing energy than organisms in lower trophic levels have.
d)
There is less available energy in the fourth trophic level because of the loss of energy through metabolism in each of the lower trophic levels.
