Week 4 >> Module 04 Quiz

Question 1

Which of the following is a form of active dispersal?

1 / 1 point

Floating with water currents

Phoresy

Hitchhiking on vehicles

Wind dispersal

Muscle-powered flight

==================================================

Question 2

Which one of the following insect leg specialisations is modified for jumping?

1 / 1 point

Fossorial legs

Saltatorial legs

Cursorial legs

Raptorial legs

Natatorial legs

==================================================

Question 3

Insect wings are attached to which thoracic segment(s)?

1 / 1 point

Mesothorax and Metathorax

Metathorax

Mesothorax

Prothorax and Metathorax

Prothorax

==================================================

Question 4

Which of the following modified wings are heavily sclerotized?

1 / 1 point

Hemelytra

Scales

Halteres

Tegmina

Elytra

==================================================

Question 5

What is the function of the halteres in flies? Select 2 that apply.

1 / 1 point

Mate attraction

Escape from predators

Inform the fly about the speed and direction of its flight

Protection of membranous wings

Maintain flight stability

==================================================

Question 6

Which of the following methods are often used to study insect flight?

1 / 1 point

Digital particle image velocimetry

Wind Tunnels

Flight mills

Wind tunnels and flight mills

Digital particle image velocimetry, wind tunnels, and flight mills

==================================================

Question 7

In what way can insect migration differ from other animal migration events?

1 / 1 point

Migration is an energetically costly, exhausting activity.

Development of the migratory syndrome

Movement is driven primarily by the efforts of the migrating individual

During migration the individuals remain unresponsive to stimuli that terminates movement

The migratory process can take place over multiple generations

==================================================

Question 8

Which of the following form the indirect flight muscles? Select 2 that best apply.

1 / 1 point

Asynchronous muscles

Basalar muscles

Synchronous muscles

Dorsoventral muscles

Dorsal longitudinal muscles

==================================================

Question 9

How can insect migration complicate conservation strategies?

1 / 1 point

Migration that takes place across a wide range can require coordinated efforts between countries

Migrating insects arrive to their sites in huge numbers, which can cause large disturbances to delicate ecosystems

Insect migration often takes place over different routes each year, which can make them difficult to track

Insect migration is accidental, which can make their populations difficult to monitor

==================================================

Question 10

Which of the following insects achieves movement with the aid of a hydrostatic skeleton? Select 2 that apply.

1 / 1 point

Ladybird beetle

Butterfly

Caterpillar

Aphid

Maggot
