Answer:
A. the atom is made up of the mostly empty space with tiny, dense, positively-charged nucleus.
Explanation:
<span>The right answer is: *some of the energy that had been stored as chemical energy is lost as heat.
Breaking down an organic molecule into smaller ones is part metabolism of all the living organisms. It is called catabolism.
Catabolism is the set of reactions of molecular degradation of the organism considered. It is the opposite of anabolism, all synthesis reactions. Catabolism and anabolism are the two components of metabolism.Catabolism reactions are oxidations (or dehydrogenations) and they are thermodynamically favorable, that is they are exergonic (yielding chemical energy, producing energy). A part of this energy is used for biological activities, like moving, building or binding molecules together. The other part is released as heat. (You can take an example in the real life like running, the energy lets you moving and produces by the way heat)</span>
The right answer is human embryonic stem cells (hESCs).
Emerging embryonic stem cells are endowed with two important capacities: that of multiplying to infinity, by simple division (self-renewal), and that of giving birth to all types. of cells of the body (pluripotency).
These properties open up many perspectives, not only for regenerative medicine (including cardiology) but also for the study of genetic diseases and the development of treatments.
People with HIV are unable to fight off these rare diseases because they have a weakened immune system.
Testosterone is the principal male sex hormone.
