tubes on the inside of the insects body

The airway that leads from the larynx (voice box) to the bronchi
a muscular partition separating the abdominal and thoracic cavities; functions in respiration
a flap of cartilage that covers the windpipe while swallowing
chromosomes become visible as paired chromatids and the nuclear envelope disappears
chromosomes become attached to the spindle fibers and line up in the center of the cell
chromosomes move toward opposite ends of the nuclear spindle
cell begins to divide
contains only one copy of the chromosome
the chromosomes condense, and a new set of spindle fibers forms
 the centromeres of the paired chromatids align along the equatorial plate in both cells
sister chromatids of every chromosome separate and begin to move towards the opposite ends of the cell
The cells pinch in the center and divide again. The final outcome is four cells, each with half of the genetic material found in the original
