Explanation:

(1). Changes in Epidermology: Epidemiology can be defined as the study of how often diseases occur in different groups of people and the reasons behind the changings.

The main importance in determining the changes in Epidermiology is that there is measurement of disease outbreaks with respect to the risk of the population.

(2). Changes in age distribution and gender ratios: if the age distributions is towards the old people; that means that there is a decrease in population but, if the age distribution is towards children; it means that there is an increase in population.

Conversely, looking at the importance of Gender ratios; if we have more males than females in the United States of America, it means that the rate at which infants will be born will be low because Males are more than Females.

(3). Issues of possible overpopulation: when there is overpopulation, there will be cases of increased poverty which will surely affect population because death ratio will be higher.

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
