The importance of mitosis to living organisms living organisms is that it allows organisms to grow in size and repair themselves.<span> When an organism grows, its cells do not grow larger; they divide to make more of themselves through the process of mitosis, or cell division.

Answer:
Option C, No. The energy contained within these macromolecules is converted into other forms of chemical energy and kinetic energy, though some is lost as heat.
Explanation:
Breaking down of large molecules in to smaller molecules does not signify breaking down of energy stored in it and hence losing all the stored energy.
Breaking down of large molecule is necessary to convert large molecules into small easily digestible molecules so that the food energy stored in them can be stored in some other form specifically chemical energy and can be used at later stages. However, in the process of conversion of large molecules into small molecules , a certain amount of heat energy is used.
Hence, option C is correct
Answer:Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. So enzymes speed up reactions by lowering activation energy
I believe it is false...........
Microscopes allowed scientists to observe Prokaryotic cells which make up Bacteria and Archaea. These cells are small and contain no membrane- bound organelles. It allowed them to observe Eukaryotic cells with a nucleus and membrane-bound organelles that perform different life functions.
