Answer:a molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.
Explanation:
<span>C.) A pea is a dicot, so the radicle grows and gives rise to a main root and its branches</span>
If a solution process is exothermic, the energy required for dissolving the solute compare with the energy released is that, the energy requiredis less than the energy released. When we sayexothermic, heat is evolved. On the other hand,when heat is absorbed, this is called endothermic.
The only independent variable in this experiment is the amount of nitrogen Sarah uses. All of the other variables are dependent on other factor and processes, but Sarah controls the amount of nitrogen that she uses for each plant.
B is not correct because new molecules are formed so numbers can change. D isn't correct because the color often changes, for example metallic iron and clear oxygen form red rust. The arrangement of the atoms changes, too so a isn't correct. C is cotrect
