The part of the enzyme molecule that binds to its associated substrate is ACTIVE SITE.
The active site contains the catalytic groups which are amino acids which promote the formation and the break down of bonds. By breaking and forming new bonds, the enzyme substrate interaction brings about the formation of the transition state.
Answer: a hypothesis.
A hypothesis means a theory or a guessed explanation made, based on limited evidence as a starting point for further investigation.
Carbonized remains are thin, approximately two-dimensional films of carbon preserved on a flat surface of rock. They are most often black in color, reflecting the fact that they composed mostly of carbon (as is coal, which is also black in color). Most fossils that exhibit “soft part” preservation are carbonizations.
I would say the answer is the Carbon remains of the original organism.
Answer:
To survive in drought conditions, plants need to decrease transpiration to limit their water loss. Some plants that live in dry conditions have evolved to have smaller leaves and therefore fewer stomata. Extreme examples are plants with leaves that resemble spiky thorns or spines.
