They exhibit considerable molecular complexity and diversity
<span>The geologic time scale is divided into periods, which are then divided into epochs, which are further divided into ages. For example, the time of the dinosaurs lasted 3 periods (Triassic, Jurassic, Cretaceous), each period had 3 epochs (late, early, middle), and each age fit into one of those. Many epochs have more than 1 age associated with them.
As for the basis for differentiating the eras, I'm not so sure. The only one I can say for sure is the end of the Cretaceous, which is when the dinosaurs suddenly became extinct due to a meteor impact. I think the divisions are based on significant, global-scale events that changed the world.
Sorry its so long but that the answer i think >:) ur welcome

D. Eating foods full of sodium, salts, fats and sugars can contribute to all of these.
Answer:
Cellular respiration is an oxidative metabolism of glucose which takes place in the mitochondria an in the cell. Some things that can go through cellular respiration is oxygen that has foodstuff molecules that divert the chemical energy into substances.
Explanation:
These substances have a life-sustaining activity and discard things such as waste products,carbon dioxide,and water.Organisms that do not depend on oxygen degrade foodstuffs in a process called fermentation. (For longer treatments of various aspects of cellular respiration, see tricarboxylic acid cycle and metabolism.)
