Answer:
There is some truth to the claim that, "All cities today are world cities". All the emerging cities of Africa, Latin America, and Southeast Asia are linked to the global economy and, particularly, to the network of world cities, in a variety of ways. But it is also clear that various metropolises fit into the world urban hierarchy at different levels and play very distinctive roles in that wider system. Analysis of urban systems, whether global, national, or regional, from the perspective of geography or sociology, using the old human ecological framework or the newer urban political economy approach, emphasizes power and dominance. Furthermore, one of the key advantages of identifying where places fit into positions in these systems, is that "structural isomorphism" will lead to similar roles. In other words, if two cites are at or about the same level in the urban hierarchy, we should logically expect them to follow broadly similar dynamics. In the 1970s and 1980s, at a time when the neo-Marxist world-system scholarship was blossoming, an "urbanization in the world-economy" approach emerged. This perspective took its initial impetus from Manuel Castells’ suggestion that we should consider the growth of third world cities as “dependent urbanization.
Answer:
His average for 4 days is 2542.5 mg
Intake of 5th day has to be less than 1330 mg
Explanation:
In order to find the average we take the sum of intakes for 4 day ans then divide it by total number of day which is 4 days.
Average = (2150 + 3005 + 2700 + 2315) / 4
Average = 10170/4
Average = 2542.5 mg
To find the 5th day intake such that average is below 2300 mg:
Let 5th day intake = x
We apply the same method to find the average by taking the sum of intakes for 5 days and then dividing the total with 5 days now. This average has to be less than 2300 mg therefore we use the following method:
(2150 + 3005 + 2700 + 2315 + x ) / 5 < 2300
2300 = (10170 + x)/ 5 < 2300
10170 + x < 11500
x < 11500 - 10170
x < 1330 mg
Answer:
In a single-celled organism, the absorption directly involves the cell membrane. The cell membrane is responsible for keeping the shape of the cell and for deciding what goes inside the cell and what stays out. It lets the substances that help and sustain the cell in and keeps the substances that would harm the cell outside and thus it is directly involved in the absorption of nutrients.
Answer:
Part A:
The cofounding variable is a factor that could cause a result on the experiment. This would be the people taking extra food.
Independent variable would be being asked to sign in or not and take free food, because independent variable is a variable that is changed or manipulated and in this case the people were split in half and the hypothesis is that the people who didn't sign in would take more food.
Operational definitions are important when conducting research because it defines all the variables in the experiment, so it can be replicated. The operational def for the dependent variable would be "Doing the right thing even though you aren't being watched"
Part B:
The data does not support the hypothesis because even the people who signed in could've taken extra food when the dean wasn't looking. The findings cannot be generalized to all students because some students could have been taught better and can differentiate between right and wrong. So the people who were not signed in could've just taken one burger and drink, and the people who were signed in might feel obligated to take more than one burger because they had signed in and didn't just come without signing in.
The study is not a naturalistic observation because the observer did not look at the people who took the food and which side took more food.
