B. water remained a gas because earth was very hot
The precise shape of a molecule is usually very important to its function in the living cell. Molecular shape is crucial in biology because it determines how biological molecules recognize and respond to one another with specificity. ... Protein function is directly related to the structure of that protein.
Answer:
The second law of thermodynamics.
Explanation:
The global transfer of energy from fuels to electricity is about 35% efficient is most likely a consequence of the second law of thermodynamics. This second law states that as energy is transformed more it is wasted, also that the entropy of a system remains constant or increase, but never decrease over time. That is why is impossible to convert heat energy to mechanical with 100 % efficiency.
Therefore, in the production of electricity, a minor part of chemical energy (from fuels) will be transformed into energy and the rest will be lost to the environment, mostly as heat, to satisfy the second law of thermodynamics.

The solution process is exothermic because when solution become colder heat energy is released which make the process exothermic. The exothermic process is the process in which heat is released.The solution forms inorder to separate NH4+ ions and Cl- ions
Answer:
The correct answer is option b, that is, the radioactive isotope reacts in the same way as stable isotopes in the chemical reactions in the body.
Explanation:
The carbon-14 atoms, which are created by the cosmic rays associates with oxygen to produce carbon dioxide that plants captivate naturally and comprise it into plant fibers by the process of photosynthesis. Afterward, the plants are consumed by animals and human beings, thus, they take in carbon-14 as well.
The ratio of usual carbon-12 to carbon-14 in the air and in all the living species at a particular period is almost the same. These radioactive isotopes react in a similar manner as stable isotopes in the chemical reactions in the body.
