← Nature & AnimalsWhich process disrupts wing development when fruit fly imaginal discs experience prolonged hypoxia?
A)Increased apoptosis reduces cell proliferation✓
B)Elevated ecdysone accelerates metamorphosis
C)Altered Hox gene expression duplicates segments
D)Reduced cuticle deposition creates structural pores
💡 Explanation
When imaginal discs experience prolonged hypoxia, increased apoptosis occurs because reduced oxygen availability triggers programmed cell death pathways, severely limiting cell proliferation and hindering proper tissue formation. Therefore reduced cell proliferation leads to wing development disruption, rather than accelerated metamorphosis or altered patterning, which involve different regulatory pathways.
