The density of Ca will be between that of Mg and Sr
Explanation:
Ca, Mg and Sr are group II elements. They are called alkali earth metals. The correct order of the elements in this group are: Be, Mg, Ca, Sr, Ba and Ra.
Density is an intensive property of matter which describes the amount of matter(mass) per volume of a substance.
- Density varies proportionally with mass. The higher the mass, the higher its density.
- On the periodic table, atomic mass which the number of protons and neutrons in the nucleus of an atom increases down the group.
- This implies a progradation in the value of density down the group. Therefore one expects that the value of density of Ca will fall between that of Mg and Sr. It cannot be more than 2.6g/cm³ nor less than 1.74g/cm³.

The type of cell that one will likely inject is OSTEOBLAST CELLS. Osteoblasts are cells that make bone. They do this by producing a matrix which becomes mineralized leading to increase in the bone mass. Injecting this type of cell will stimulates rapid healing of broken bones.
Hello,
The answer should be "thermal energy".
Reason:
The answer is thermal energy because the heat from whatever source the person is energy is transferring heat to the chicken which is causing the chicken to cook therefore the answer is thermal (heat) energy.
If you need anymore help feel free to ask me!
Hope this helps!
