Lesson 7 Evolution of Stripes Quiz

What is the purpose of zebra stripes according to the 'Predators' hypothesis?

• To attract predators

• To confuse predators

• To regulate body temperature

• To blend in with the environment

Why did scientists find that the 'Predators' hypothesis doesn't fully explain zebra stripes?

• Lions tend to avoid zebras

• Lions are not affected by zebra stripes

• Lions are not present in zebra habitats

• Lions hunt zebras frequently

What did scientists discover about the relationship between zebra stripes and temperature according to the 'Thermoregulation' hypothesis?

• Stripes are purely for camouflage

• Stripes might help zebras stay cool

• Stripes create cooling winds over the zebra's body

• Stripes have no effect on temperature

Why do scientists believe that stripes might help zebras stay cool?

• Stripes have no effect on temperature

• Stripes create small air currents on the zebra's skin

• Stripes absorb heat from the sun

• Stripes attract cool breezes

What did the study on 'Biting Fly Avoidance' find regarding the relationship between zebra stripes and biting flies?

• Stripes deter biting flies

• Stripes have no impact on the environment

• Stripes attract biting flies

• Stripes have no effect on biting flies

Why is the study on 'Biting Fly Avoidance' considered uncertain in its findings?

• The study considered the different environments where zebras live

• The study found a strong link between zebra stripes and biting flies

• The study only looked at simple connections

• The study was based on actual sightings of the flies

What did the experiment on cooling winds over zebra stripes reveal?

• Stripes attract warm air towards the zebra

• Stripes create significant cooling winds over the zebra's body

• Stripes have no effect on air movement

• Stripes only work if there's a breeze or if the zebra moves

What did the experiment on cooling winds over zebra stripes conclude?

• Stripes are purely for camouflage

• Stripes might help zebras stay cool in specific situations

• Stripes have no effect on temperature regulation

• Stripes help zebras stay cool by creating wind patterns
