B.
muscles attach only to antennae
C.
muscles attach directly to wing bases
D.
muscles work only during molting

outgrowths of the thoracic body wall
C.
modified antennae from the head
D.
abdominal gills from the hindgut
Show Answer
Correct Answer: B. outgrowths of the thoracic body wall
Explanation:

A.
leaf-like legs used as gills
B.
long, slender legs support rapid running
C.
needle-like legs for blood feeding
D.
broad legs with pollen baskets
Show Answer
Correct Answer: B. long, slender legs support rapid running
