Question 14

Based on the Olestra potato chip experiment conducted by researchers at the Johns Hopkins University School of Medicine, match the following letters to the number with which they best correspond.

People who eat potato chips with Olestra will be more likely to get intestinal cramps than those who eat potato chips made without Olestra.

e xperiment

Olestra causes intestinal cramps.

p rediction

A set of people got regular potato chips.

c onclusion

Correct Answer:

Verified

People who eat potato chips with Olestra will be more likely to get intestinal cramps than those who eat potato chips made without Olestra.

Olestra causes intestinal cramps.

A set of people got regular potato chips.

Some people complained of intestinal problems after eating chips containing Olestra.

Olestra

One thousand and one hundred people between the ages of 13 and 38 were asked to watch a movie and eat potato chips.

A subset of people got Olestra-containing chips.

Percentages are about equal. Therefore, Olestra is not the cause of intestinal cramps observed in some people who have ingested Olestra-containing food.

In the control group, 17.6 percent of people reported having cramps later, while in the experimental group, 15.8 percent of people had cramps later.

Question 18

Classification . Answer the following questions in reference to life's diversity. Choose only the most correct answer.

Often found in extreme environments while having no nucleus, these organisms are closer genetically to eukaryotes.

fungi

These multicelled consumers include herbivores and carnivores.

protists

Besides feeding themselves, these multicelled organisms serve as food for most other organisms.

bacteria

Correct Answer:

Verified

Often found in extreme environments while having no nucleus, these organisms are closer genetically to eukaryotes.

These multicelled consumers include herbivores and carnivores.

Besides feeding themselves, these multicelled organisms serve as food for most other organisms.

This single-celled or multicelled eukaryotic consumer breaks down material outside itself, then absorbs nutrients released from the breakdown.

Members of this domain have a nucleus and numerous membrane-bound organelles.

Multicelled consumers that actively move about during at least part of their lives.

These prokaryotes are able to colonize extreme environments such as hydrothermal vents on the seafloor.
