Answer:Validity
Explanation:
Validity is measure of how valid the research is which means it gives solid relevant result which were initially intended. It is a test of how valid both your design and method of the research is.
There are various factors that can affect validity of the research.
There are internal factors that can affect validity of the research those are the ones that occur within the study such as failure to monitor vital variables of the study or using the inaccurate instrument to gather the needed data.
Below are the factors that has an impact on internal validity.
-size of the studied population
-instruments used
-history
-subject variability
-available time to gather data
- attrition
External validity are affected by the external factors such as the place where you conduct your research which may restrict the ability to obtain actual results . It can also be affected by the things like not being able to balance your subjects for example focusing on one gender and race eventhough your research is about all the types of people at large.
Crucial factors that affects external validity.
- The effect of time
- method use to collect data
- characteristics of the chosen population
- experiment effect
- interaction of subject selection
Answer: A. Ways a person can become a US citizen.
Further detail:
- Anyone born within the borders of the United States is considered a US citizen by birth. This is even true if the parents of the child born in the US are not citizens. Being born on US soil is a way a child is considered a US citizen. This has become a matter of some contention in recent years, as some opponents of illegal immigration accuse immigrants of coming across the border to have a baby just so that baby can have US citizenship.
- If either of a set of parents are US citizens, a child born to those parents is also a US citizen, even if you were born in a foreign country. So if parents are stationed overseas or traveling, and a birth occurs outside the United States, that child still has US citizenship.
- For those not citizens by being born on US soil or to a US citizen parent, applying to become a naturalized citizen is the path for pursuing citizenship. On the USA.gov website, you can find a full desciption of "How to Apply for US Citizenship" and the naturalization process.

Answer:b. After three generations of breeding the smallest dogs, the average size of pups in a litter decreases by 3 pounds. -- Evolution
Explanation:Evolution refers to changes in inherited traits which occurs over successive generations.
These are genetical traits which are passed from parents to offsprings.
It may be due to mutation or combination of genes that causes genetical variations over time.
It is also driven by natural selection in which subjects with resistant genes stay long and have these passed from generation to generation or resulting to some genes being eliminated.
