Density is mass divided by volume
Answer:
Osteochondral Progenitor cells
Explanation:
Osteochondral Progenitor cells are cells that can form a specific type of tissue. These cells form cells that can give rise to the bone and its components, especially fibers. These Progenitor cells originate from the mesenchymal stem cells.
The cells which form the bone are known as the osteoblasts and the cell which forms the fiber is known as the chondroblasts.
Thus, Osteochondral Progenitor cells is correct.
Answer:
Oxygen
Explanation:
The formula for cellular respiration is oxygen + glucose -> water, carbon dioxide, energy. You can already cross out A and D because they aren't in the formula, so you have two left, water and oxygen. The reason why it is oxygen and not water is because without oxygen you can't even have water. also, I just got this right on my test :-)
The scientific method is a process of steps in order to get a conclusion. First, a scientist will observe something. It could be really anything. Then he/she will ask themselves a question. Like how does it do that? Or why does it do that?
Then they will form a hypothesis. This is where you will ask yourself what will be the outcome of the experiment.
Next you actually perform the experiment. If the experiment comes out as your hypothesis predicted, then you accept your hypothesis.
If not, you reject your hypothesis.
Of course, in science you just don't do one experiment. You do it multiple times and even with different circumstances.
I believe it is scientific laws.
