Answer:
The correct answer is: The participants' abilities to solve geometry problems.
Explanation:
Researches contain both dependent and independent variables.
In a research the dependent variable is the variable that the researcher wants to identify if it changes by modifying the independent variables.
Independent variables are multiple factors that if modified they may or may not change the dependent variable.
In this particular case, Dr Martinez wants to prove the effects of diet on mental alertness. He proceeds to instruct the participants to eat breakfast that's either high in carbohydrates or high in protein (Independent variables) and then Dr. Martinez then measures the participants abilities to solve geometry problems (Dependent variable).
In conclusion, the dependent variable in this study is: Participants' abilities to solve geometry problems.
Answer:
Moches: Well developed and established irrigation channels and creation of labor classes
Chimus: Planning to build cities, messaging system.
Explanation:
Moches and Chimus are civilizations that predated the Incas, but that contributed in a great way to the establishment and success of the Inca culture.
The moches influenced the Incas to develop and establish efficient irrigation channels that would allow an advance in agriculture, generating more wealth and an efficient trade. It also influenced the creation of labor classes, allowing the collection of taxes to be equivalent to social class and that no one could be exploited.
The Chimus, in turn, influenced the Incas to plan the construction of new cities very well, with major works that showed the wealth of the empire, in addition to providing comfort to the population. They also influenced a system for transmitting messages through corridors, which was very modern and efficient at the time.

Answer:
The conflict theorist would argue from the point of view of the society being in perpetual competition as a result of inequality of distribution of resources and power. The rich would not pave the way for cheaper technology as a result of them purchasing early version of expensive technologies but rather, everyone would aspire to be the first to buy such early version of technology due to prestige associated with it.
On the long run, the conflict theorists makes more sense due to the fact that, as more people aspire to buy the early version of technologies, it creates extraordinary demand for the goods. this would force the manufacturers to employ more workers inorder to meet up with the demand thereby leading to fall in the prices of such goods. An example is the Toyota brand cars that is popular in some countries.

Answer:
The type of sampling used in Jankowski's study of gangs is Option D. Stratified sampling.
Explanation:
With stratified sampling, the researcher will partition the population into different groups, usually based on some characteristic that is common to that group. In this case, it was the different kinds of gang membership. Then, the researcher will take a sample of people within each specific group using another sampling method like simple random sampling for instance. The groups that are used in stratified sampling are called strata. Another example would be a national survey that is divided into strata of the different major ethnic groups that comprise the national population.
