Document Summary
Potential to differentiate with different types of cells. Lizards and salamanders can regenerate lost tails and appendages. Each cut piece will regenerate an entire flatworm. If the head is split down its centre lengthwise, two heads can regenerate and the flatworm will continue to live. (video) every piece of the planarian you cut regenerates itself. Homework: list and describe five skills that you hope to develop in this course. Science is applying and understanding the natural and social world following a systematic methodology based on evidence. Observations that are made-often the starting point of a scientific investigation: rational/natural explanations. Very few questions are off-limits in science-but the answers science can provide are limited to the natural world. There is a biological explanation for regeneration and this is a phenomenon that can be studied: repeatability and reproducibility (and reliability) Scientific results are always subject to confirmation by the same (original) or other investigators.
