4. which of these statements is a principle of the cell theory that supports the idea that new cells will replace damaged cells in a scraped knee?
a. all living things are compose of one or more cells
b. cells are the basic units of structure and function in living things
c. all cells arise from previously existing cells
d. most cells are too small to be viewed with the unaided eye

C. All cells arise form previously existing cells. This is because the scraped knee's cells would be replaced by the exact same ones that were removed. Kind of like "Out with the old and in with the new... yet the exact same..!"

Hope this helps!

The answer is C. All cells arise from previously existing cells

None of the other choices directly relate to the topic of cells replacing each other. The third option (c) does relate to the question and supports the idea that cells replace each other. Therefore, the answer is C.

Hope this helped. Have a great day!

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
