A unique feature of the nucleus is that it disassembles and re-forms each time mostcells divide. At the beginning of mitosis, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down, resulting in the release of most of the contents of the nucleus into the cytoplasm.

The correct answer for the question that is being presented above is this one: "Urochordata." <span>Lancelets have all chordate characteristics and segmentation in the adult. Tunicates (Sea Squirts), Subphylum: Urochordata Gill slits are the only chordate feature retained by the adult form.</span>
Telophase because that is when the daughter cells are formed
Answer:
4. when the ADP is released and the myosin cross-bridge moves to the right in the animation
Explanation:
Cross-bridge formation occurs when the myosin head attaches to the actin while adenosine diphosphate (ADP) and inorganic phosphate (Pi) are still bound to myosin. ADP and Pi is then released, causing myosin to form a stronger attachment to the actin, after which the myosin head moves toward the M-line, pulling the actin along with it. As actin is pulled, the filaments move approximately 10 nm toward the M-line. This movement is called the power stroke, as movement of the thin filament occurs at this step. In the absence of ATP, the myosin head will not detach from actin.
