Question 1

Which of these are important elements in building organic molecules? Select 3 that apply.

1 / 1 point

Helium

Nitrogen

Carbon

Phosphorous

Iron

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

Question 2

Why is nutrient cycling important?

1 / 1 point

It allows nutrients to cycle within an organism

It releases proteins from the earth into the atmosphere to cycle through the ecosystem

It is an alternate mode of personal transport that doesn’t produce greenhouse gases

It maintains appropriate levels of essential elements in an organism

The process recycles chemical elements that are essential for life to continue on Earth

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

Question 3

Insects in which of these feeding guilds could potentially damage human made structures?

1 / 1 point

Coprophages

Durophages

Mycophages

Xylophages

Necrophages

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

Question 4

Why are coprophages important? Select 3 that apply.

1 / 1 point

They reduce the amount of suitable habitat for parasitic worms in pastures

They help investigators determine post-mortem indices

They help maintain healthy pasture ecosystems

They help recycle dead wood back into the forest ecosystem

They recycle organic material back into the soil

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

Question 5

What is the definition of an instar?

1 / 1 point

The amount of time between successive insect moults

A star-shaped hole created by an insect burrowing into carrion

Specialized spines that help insects move along a soil surface

The different stages of decomposition

A stage between two periods of molting in the development of an insect

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

Question 6

Developmental rates in insects are most influenced by:

1 / 1 point

Fat content

Predation

Disease

Pesticide exposure

Temperature

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

Question 7

Maggots are collected during a homicide investigation. Which of the following should be done?

1 / 1 point

Identify the maggots based on morphology

Rear the maggots to adulthood for identification

Leave the maggots on the corpse until pupation

Identify the maggots based on morphology and rear the maggots to adulthood for identification

Identify the maggots based on morphology, rear the maggots to adulthood for identification, and leave the maggots on the corpse until pupation

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

Question 8

The most difficult aspect of using flies in forensic entomology investigations is:

1 / 1 point

Identification of larvae based on morphology is difficult

Flies have fast life cycles, making the first generation difficult to identify

Flies are fast fliers, which makes them extremely difficult to catch

Adult flies disperse far from their larval food source, making them difficult to track

It is difficult to determine the age of adult flies based on morphology

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

Question 9

What information CANNOT be provided by insects in forensic investigations?

1 / 1 point

Movement of the victim after death

How long a body has been buried

The postmortem interval

Presence of chemicals in the victim

Presence of wounds

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

Question 10

What term is used to describe the number of generations of an insect per year?

1 / 1 point

Succession

Stadia

Generation

Voltinism

Instars
