Capuchin Monkeys and Millipede Secretion Quiz

What potential risk is associated with the use of millipede secretion by capuchin monkeys?

• The secretion is highly nutritious.

• The secretion is toxic and carcinogenic.

• The secretion attracts more insects.

• The secretion causes dehydration.

Why do capuchin monkeys anoint themselves with millipede secretion, especially during the rainy season?

• To attract mates.

• To protect against insects, particularly mosquitoes.

• To mark their territory.

• To cool themselves down.

How long must a capuchin's first behavior last to be recorded during systematic behavioral sampling?

• At least 2 seconds

• At least 5 seconds

• At least 10 seconds

• At least 1 minute

Which method was used to analyze the extracts from the millipede secretion?

• Gas chromatography–mass spectrometry (GC-MS)

• High-performance liquid chromatography (HPLC)

• Ultraviolet-visible spectroscopy (UV-Vis)

• Polymerase chain reaction (PCR)

During which season does anointing occur according to behavioral observations?

• Rainy season

• Dry season

• Winter

• Summer

What are the two volatile components found in the secretion of millipedes as identified by GC-MS analysis?

• 2-methyl-1,4-benzoquinone and 2-methoxy-3-methyl-1,4-benzoquinone

• Methanol and ethanol

• Acetic acid and citric acid

• Benzene and toluene

What is the proposed purpose of capuchin monkeys anointing themselves with millipede secretion?

• To acquire benzoquinones for defensive use against insects

• To derive nutrients from the millipedes

• To clean their fur

• To attract mates

What is the primary function of benzoquinones in many arthropods?

• To aid in digestion

• To serve as antinsectan agents

• To attract mates

• To help in locomotion
