Answer:
Birth Rate
Now, this might seem very obvious to you, but when babies are born, it results in a population change! Social scientists who study this trend have some key terms, though. First, the fertility rate in a country refers simply to the number of children born. This is different from the fecundity rate, which is the number of children who could be born in a given society. In other words, fecundity is the biological capacity of humans to produce children.
Death Rate
Just as when babies are born, when members of a society die it changes the population. This might be a bit morbid to think about, but scientists refer to this as the mortality rate, which is simply the number of deaths that occur in a society. This is usually calculated by looking at the number of deaths per 1,000 individuals. In the United States, for example, the death rate is 8/1000 people. Just like birth rate, the death rate in a country depends on things such as availability of quality medical care, disease, war, or famine.
Migration Rate
One important factor that accounts for a change in population is migration. At the broadest level, migration refers to movement; it's the flow or circulation of people in societies. There are two kinds of migration: emigration and immigration. Emigration means to leave one's own country for another. Immigration means to enter into a country other than one's own.

Thus, the improvements a smoker will experience first, second, third, and fourth once he or she stops smoking includes the following;
1. Pulse rate decreases: the rate at which the heart beats and pumps blood decreases significantly as compared to when the individual was an active smoker.
2. Carbon monoxide levels improve: there are less deposits of carbon monoxide in the body system of the individual.
3. Circulation improves: the transportation of blood by the arteries and veins becomes efficient and better than when the individual was actively smoking.

Explanation:
Binge Eating Disorder (BED) is a serious, life-threatening disorder which may <u>lead to several metabolic diseases</u> and complications like diabetes mellitus and hypertension. This should be immediately addressed by a psychiatrist in order to give intervention earlier to avoid development of chronic diseases.
- According to the Diagnostic and Statistical Manual of Mental Disorders - 5 (DSM-5) criteria for BED, it should have the following signs and symptoms
1. Recurrent binge eating episodes should be both characterized by the following,
<em>"Eating, in a discrete period of time (e.g., within any 2-hour period), an amount of food that is definitely larger than what most people would eat in a similar period of time under similar circumstances,"</em> and
<em>"A sense of lack of control over eating during the episode (e.g., a feeling that one cannot stop eating or control what or how much one is eating)."</em>
2. It is then associated with any 3 of the following
- <em>"Eating much more rapidly than normal.
"</em>
- <em>"Eating until feeling uncomfortably full.
"</em>
- <em>"Eating large amounts of food when not feeling physically hungry.
"</em>
- <em>"Eating alone because of feeling embarrassed by how much one is eating.
"</em>
- <em>"Feeling disgusted with oneself, depressed, or very guilty afterward."</em>
3. Marked distress regarding binge eating is present.
4. The binge eating occurs, on average, at least once a week for 3 months.
5. The binge eating is not associated with the recurrent use of inappropriate compensatory behaviors (e.g., purging) as in bulimia nervosa and does not occur exclusively during the course of bulimia nervosa or anorexia nervosa.
