Which statement correctly distinguishes internal from external regulation with examples?
Internal signals come from outside the cell like hormones; external signals come from DNA
Internal signals come from the cell's own nucleus like DNA; external signals come from outside the cell like hormones
Internal signals are always chemical; external signals are always electrical
Internal regulation only occurs during exocytosis; external regulation only during endocytosis

Spindle fibers connect to the centromere; chromosomes line up in the middle of the cell
During Anaphase, what is the outcome of sister chromatid separation?
Chromosomes line up at the equator
Two nuclei form
Individual chromosomes are pulled to each side of the cell
Spindle fibers break down
Which combination correctly matches Telophase and Cytokinesis events described?
