Answer:
The ability and tendency of certain systems to maintain a relatively constant internal state in spite of changes in external conditions; this ability is achieved by the presence of feedback mechanisms which can adjust the state of the system to compensate for changes in the state caused by the external environment. It is exemplified in homeothermal biological systems, such as animals which maintain relatively constant blood temperature and composition in spite of variations in external temperature or the composition of the food ingested.
Explanation:
Answer:
Li is more reactive then Be.
Explanation:
As you go to the farther left and down on the periodic table, the higher that element reactivity is.
Well Mendeleev<span> predicted the existence and properties of elements that werent discovered at the time</span>
Car D
Because it is the heaviest. Kinetic energy is directly proportional to the velocity and mass of the object. All the cars have the same velocity. But Car D has the most mass. So, it has most kinetic energy, because more the mass more the energy.
I believe it is <span>d. the bonds of both the reactants and the products are formed.</span>
