C. Behavior
Although it does have some impact on the spread of disease, it is not a preventive measure to combat the spread of disease because it cannot be easily controlled.

Slightly fewer than 4 million babies are born in the United States each year, and the details of how, when, and where they arrive are always shifting. Total fertility rate is an estimate of the average number of births a group of women have over their lifetime. The U.S. fertility rate has been declining since 2007.
<span> This is an example of a quantitative </span><span>observation</span>
<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

They are carbohydrates containing a terminal aldehyde or ketone group which can undergo oxidation reactions. By reacting with free amino groups in amino acids, peptides and proteins, reducing sugars can form unique compounds essential for the desirable flavor and aroma of baked goods.
