Free Response: Question #29
1. Adrenoleukodystrophy (ALD) is a sex-linked
genetic disorder that results from
accumulation of specific types of fats in a
child’s brain. These fats are not broken down
& disposed of & they build up as a result.
Untreated, this causes severe brain damage &
ultimately death. Which type of organelle in
the cells appears to be malfunctioning.
Explain your answer.
Free Response: Question #30
Adrian has constructed a miniature ecosystem that
includes tiny animals in a sealed glass jar. He measures
the concentrations of oxygen and carbon dioxide of the
air inside the jar periodically.
After recording an increase in oxygen and a decrease in
carbon dioxide, he concludes that there are too many
plants for the number of animals inside the jar.
A. How did the measurements lead him to this
conclusion?
B. If Adrian places the glass jar in a room that receives
less light, how will this help balance the ecosystem
in the glass jar?
