19.

Myriapoda includes scorpions, centipedes, and proturans.

20.

The wings of a midge may beat at frequencies of 1,000 cycles per second, which is much faster than the frequency of nerve impulses to flight muscles.
A)True
B)False
21.

Insects are not capable of regulating their body temperature.
A)True
B)False
22.

Gas exchange in insects involves respiratory pigments dissolved in the hemolymph.

A)True
B)False
27.

Recent reevaluations of arthropod phylogeny suggest that the subphylum Crustacea may be a paraphyletic group.
A)True
B)False
28.
