I believe it is Osteocyte - Compact Bone Tissue - Femur - Skeletal System
There are, 7 Carbon atoms, 10 Oxygen atoms, 12 Hydrogen atoms in the reactants and 1 Carbon atom, 3 Oxygen atoms, 2 Hydrogen atoms in the products.
<h3>How to count the number of atoms in reactants and products?</h3>
- Write down the chemical formula that is:
+ 
→ 
+ 
+ 
- List all the atoms present in the equation:
C
H
O
- Count the number of atoms of the element of each molecule in the reactant.
C=6
O=8
H=12
- Count the number of atoms of the element of each molecule in the Product.
C=1
O=8
H=2
Hence there are, 6 Carbon atoms, 8 Oxygen atoms, 12 Hydrogen atoms in the reactants and 1 Carbon atom, 3 Oxygen atoms, 2 Hydrogen atoms in the products.

I'd say stone tools. Stone can be chiseled or left alone and be used as a weapon to defend one's self, or as a way of getting food.
Although the actual questions are missing from your ask, here's how you can tell.
If the study will be messed up (added bias) through interaction with the subjects the study should be observational. For example if a biologists wanted to study the eating habits of wild birds in the tropics, they would need to do an observational study. if they did a controlled experiment, the birds will change their eating habits based on human interaction, thus making the study invalid.
If the study requires specific measurements, close monitoring, or contact and interaction with the subjects the study should be a controlled experiment. For example, if a scientist wanted to test out a new drug, the health of patients would need to be closely monitored.
Answer:
Osmosis
Explanation:
"a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane."
