Answer:
a. longitudinal
Explanation:
A longitudinal study examines a given group over a long period of time, so collecting data from the same group of 30 people over their lifetime certainly fits that definition. It's more like an evolution study.
A cross-sectional compares different groups at the same point in time. So, it's more like a survey.
A microgenetic is much focused in time, providing multiple data sets in a short time to examine rapid evolution of a subject.
An experimental study design will make interactions and experiments with the study group, while this is not the case here apparently, and experimental is usually for a much shorter period than a generation.
Your descriptors are mostly correct, assuming the column headings are something like ...
... function ... domain ... range ... odd/even ... intercepts ... increasing/decreasing ... ??? ... critical points
_____
√x is increasing on the interval [0, ∞). There is no branch where the function is decreasing.
1/x has a critical point at x=0. The slope is undefined there.
187.7000000 is the answer.
Answer:
migrant diffusion.
Explanation:
Migrant diffusion was the main mechanism by which folk customs spread to popular culture. Folk customs such as sports and music originated in small, limited regions that shared common cultural traits. Its global spread was limited by geographical and environmental barriers, as well as limited technology. Therefore, the main way in which these spread was through migrant diffusion. As people moved away from their places of origin, they took these traditions with them, spreading them to other areas of the world.
