Answer:

Descriptive research

Explanation:

If our goal is to estimate the prevalence of a disease or exposure in a population, we are talking about descriptive research. Whenever we are trying to describe the characteristics of a population or a phenomenon (in this case the frequency of a disease and exposure to it) we are doing a descriptive study. The results of this type of studies are usually represented in descriptive statistics and percentages. For example, from this sort of survey we would find out the percentage of population that suffer this disease.

direct democracy

Why is North Africa subject to foreign invasions?
levacccp [35]

North Africa is subject to foreign invasions because its location on the Mediterranean Sea provides ports and access to other waterways.

Answer: Option A

<u>Explanation: </u>

The geographical orientation of the continent of Africa has allowed it to form the Mediterranean Sea with the major European peninsulas on the other end of the sea.

This attribute of a neighbourhood with the important European countries and access to the Atlantic Ocean through the Strait of Gibraltar made North Africa an attractive region in the contemporary world geopolitics.
