Answer: Thermal energy refers to the energy contained within an object that changes its temperature. Heat is the energy of thermal energy. A chemical change happens when one substance and another substance form into two or more different substances.
I'm guessing here but, some advantages are, embryonic stem cells are very effective at repairing damaged tissues, but they are difficult to obtain, and either have to be obtained from umbillical chords of babies, or from fertilized embryos from a laboratory. So I am guessing they would be expensive/difficult to source because you would either have to collect umbillical chords from babies, or have to purchase eggs from women, and they are ethically questionable to use because you are essentially making potentially viable embryos and then killing them. Hope this helps.
Explanation:
The answer is true.
All of them bunched together is called a community
B.) Decreases (As the growth rate of a population increases, the doubling time decreases.)
Conditions are being used to try and isolate solid hydrogen cooled to low sufficient temperatures, hydrogen can grow to be strong at high sufficient pressures, and while the detail solidifies, it turns into steel.
At exceedingly low pressures, Hydrogen is compressed stable hydrogen turned into obvious. as the compression intensified, it began to show opaque and black. but at 495 Gpa, the hydrogen becomes shiny and reflective, indicating its transformation into a metallic despite the fact that the researchers cannot make sure whether or not it becomes solid or liquid).
Hydrogen can also be stored on the surfaces of solids (via adsorption) or inside solids. In adsorption, hydrogen is attached to the surface of cloth both as hydrogen molecules or as hydrogen atoms.
