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.
Answer:
b. To the extent possible, solid reagent should be added to the solid waste container and broken glass should be added to the glass waste. Hazardous materials should never be added to the glass waste, and broken glass should only be allowed in the solid waste with the TA's approval.
Explanation:
All reagents, waste, equipment, and packaging used in a laboratory should be disposed of safely and appropriately to avoid environmental contamination and to avoid an accident if improperly disposed of. In a laboratory each type of reagent, waste, packaging, and equipment must be properly disposed of and specific to each. Therefore, we can conclude that if a solid reagent beaker falls off a laboratory bench and cracks, the correct thing to do is to take the solid reagent as much as possible and add it to the solid waste container and broken glass to glass waste. Hazardous materials should never be added to glass waste, and broken glass should only be allowed on solid waste with AT approval.
The answer is true because it is controlled
