For the researcher to be able to effectively study how the amygdala reacts when participants watch emotional videos, he can use FMRI technology to answer this question.
<h3 /><h3>Functional Magnetic Resonance</h3>
It is a technique that is based on measuring brain activity according to changes in blood flow, because when an area of the brain is active, there is also an increase in blood flow to that area.
This exam is effective for mapping activities in the brain of humans and animals, through the analysis of images that show a change in blood flow according to a certain exposure of the individual.
It is necessary to use contrast to perform this exam, which can also be useful for electroencephalography and brain physiology exams.
The correct answer is:
- Functional Magnetic Resonance Imaging (FMRI)

Answer:
the price of food will fall in Alpha and rise in Beta
Explanation:
Based on the information provided within the question it can be said that in this scenario If the countries engage in free trade, the price of food will fall in Alpha and rise in Beta. This is mainly due to the fact that Alpha has a comparative advantage in drinks but not food due to drinks being labor intensive and Alpha having enough laborers to handle it. Therefore Beta will most likely trade their food for drinks causing prices of food to rise in Beta.
Answer:
d)
Explanation:
A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen. It also has the characteristic that a simple random sample is meant to be an unbiased representation of a group.
In a simple random sample, the sample is always smaller than the population (since it's a subset of it).
There are also two kinds of random sample, one with replacement (in which the same element is put back into the population and it can be taken for the sample again, thus is being selected more than once) and one without replacement (in which every element can only be selected once).
There is no really a standard size for each sample as long as it is smaller than the population, however, smaller samples can tend to reduce reliability and therefore can bias our experiment so they are not recommend. Also the idea of the sample is that we can generalize our observations into the general population and this can happen with larger samples.
Thus, the characteristics that apply to random sampling are:
d) All observations in the population are equally likely to be selected into the sample.
