Multiple Choice

How did the wings of the pale grass blue butterfly help explain the increased

rate of abnormalities seen in the butterfly population six months after the

nuclear accident at the nuclear power plant?

• The pale color of the wings made it easier to detect abnormalities

  the radiation caused in the wing DNA.

• The small size of the wings made detecting abnormalities in the wing

  proteins of the butterfly easier after the nuclear accident.

• The small size of the wings made flying far from the nuclear accident

  difficult so the butterfly DNA was exposed to radiation that caused

  abnormalities in the proteins formed.

• The wings provided additional areas for the butterfly to capture

  nuclear radiation after the accident and led to increased levels of

  abnormalities seen in butterfly proteins.

Multiple Choice

Based on the data shown in the Rate of Abnormal Appendages and Butterfly

Forewing Size graphs, which conclusion can most likely be made?

• The development of the appendages and forewings in butterflies is

  controlled by the same cell.

• The development of the appendages and forewings in butterflies is

  controlled by different groups of specialized cells.

• The DNA and the proteins involved in the development of butterfly

  appendages and forewings were affected by radiation.

• The DNA in the cells of butterfly appendages and forewings was

  affected by the radiation, but it had no effect on the proteins formed.

Multiple Select

Which evidence supports the claim that genes that control the life cycle and

development of pale grass blue butterflies were affected similarly by the

accident at the nuclear power plant? Select the two that apply.

• The abnormalities seen in offspring generations of butterflies were

  greater than in the parent generation.

• The abnormality rate in appendages for the butterflies increased

  closer to the site of the nuclear accident.

• The abnormalities caused by the radiation were only seen in the eyes

  and wings of pale grass blue butterflies.

• The average eclosion time was longer for radiation-exposed butterflies

  that were closer to the site of the nuclear accident.

• The pale grass blue butterflies fed on plants that grew near the

  nuclear power plant, which caused mutations in the butterfly DNA.

Multiple Choice

Which claim is supported by the data in the Abnormalities in Several

Generations of Butterflies table?

• Exposure to radiation only resulted in abnormalities in butterfly wings.

• Exposure to radiation affected the DNA in butterfly cells and was

  passed on to the offspring.

• Pale grass blue butterflies were more affected by radiation exposure

  than other butterfly species.

• Larger doses of radiation led to more butterfly deaths in the

  parent (P) generation.

Multiple Select

Which claims explain the increased abnormality rate seen in the F1

generation of butterflies that were caught two months and six months after

the nuclear accident? Select the two that apply.

• Each generation of offspring produced by adults that were exposed to

  nuclear radiation randomly mutated.

• The scientists collected adult butterflies for the study from areas with

  the highest levels of nuclear radiation.

• The parent populations of butterflies that produced offspring were

  those with the largest number of genetic abnormalities.

• Nuclear radiation caused genetic damage in the adult butterflies that

  was inherited by the offspring generation.

• Mutations that occurred during meiosis led to offspring generations

  with more mutations than the parent generation.
