Explanation:
The evidence that supports the conservation law is that Carbon dioxide becomes glucose and oxygen during photosynthesis. The law of conservation of mass states that in a chemical reaction, mass is neither created nor destroyed.
<span>The correct answer is "Sudden changes in the somatic cells of organisms play a key role in the process of adaptive evolution". Adaption in evolution is caused by sudden gene mutations that affect an organism's offspring and give it - potentially - a better chance of survival. For example, a giraffe who passed on a mutated gene for a slightly longer neck to its offspring gave its offspring a better chance of reaching untouched food, and thus a survival advantage.</span>
Mitosis is when a single cell splits apart and creates two new cells that are identical to the parent cell.
Stem cells are what allow planaria to grow and regenerate as the stem cells can change into any of the cells that make up the planaria.
