What is a chromatid? a. a chromosome found outside the nucleus b. a chromosome in g1 of the cell cycle c. a special region that holds two centromeres together d. another name for the chromosomes found in genetics e. a replicate chromosome

e. a replicate chromosome

Explanation:

In the cell that is in the process of division, each condensed chromosome appears as a pair of rods joined at one point, the centromere.  These two chromosomal "halves", called sister chromatids, are identical and arise from the duplication of the original chromosomal filament that occurs at the interphase just before cell division begins.

During the process of cell division, the sister chromatids separate: each chromatid migrates to one of the forming daughter cells.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
