← Nature & AnimalsWhich process causes coordinated tissue remodeling during larval insect metamorphosis?
A)Programmed cell death directs morphology✓
B)Increased juvenile feeding inhibits development
C)Elevated hemoglobin levels induce shedding
D)Intestinal flora modification boosts growth
💡 Explanation
When hormone levels shift, programmed cell death (apoptosis) occurs because signals activate caspases that selectively destroy larval tissues while imaginal discs develop adult structures, guiding morphogenesis. Therefore apoptosis contributes to coordinated remodeling, rather than feeding, hemoglobin, or flora modifications, which affect nutrient uptake and growth regulation.
