Answer:
I THINK THE ANSWER IS... A
Explanation:
Density don’t depend on mass and volume because there are different mass and volumes when it becomes density
arbon, as with many elements, can arrange its atoms into several different geometries, or "allotropes." In pure diamond, every carbon atom is covalently bonded to exactly 4 other carbon atoms in a very specific and energetically favorable geometry. The diamond cannot be broken or scratched unless many covalent bonds are broken, which is difficult to do. In another common allotrope, graphite, every carbon atom is covalently bonded to only 3 other carbon atoms, and the atoms are arranged in sheets that are not covalently bonded to each other. The sheets can be broken apart easily, ultimately meaning that graphite can be easily scratched. Coal is composed of particles of different allotropes of carbon, and some "amorphous carbon," which has no defined geometry in its atomic structure. Without a continuous network of covalent bonds, coal is easily scratched (i.e. it is not hard).
When stress becomes long-term and is not properly addressed, it can lead to a number of more serious health conditions, including depression. It's high blood pressure.
The one that is true about cells is Number two. The cell is the basic unit of a structure and function of life. The cells are what makes us living things. All living things are made up of cells.
