They use homologous structures as base of classification
The generalizability of a study increases when: E) The sample is more representative of the population.
The generalizability of a study is simply a measure of how useful, relatable and relevant the results of a study are for a larger (broader) percentage of a population. Thus, a study is considered to have good generalizability when its results are broadly useful and applicable to a larger (broader) percentage of a population.
Basically, the generalizability of a study is the application of research findings and test results based on a particular sample to a larger (broader) population.
This ultimately implies that, a sample is considered to be more representative of a population when the generalizability of a study increases.

1. You would expect the most drainage during the rainiest season, which is summer for the east coast of the US. This also coincides with hurricane season and snow melt runoff in spring-early summer. Wetlands absorb the excess water so that neighboring areas do not flood. They also act as important nurseries for sea life and have value for eco-tourism and potentially commercial farming. 2. Other than soul and sediments, run off from urban areas, pollution, and toxins can accumulate in wetlands. 3. This could create polluted waters in the Chesapeake Bay Area which would be detrimental to wildlife who use the area as a nursery, potentially devastating fisheries, there could be a reduction in ecotourism, a reduction in potable water for people and farms.
True.
Since scarcity is the basic economic problem, without scarcity there would be no need to study economics. Scarcity means when a particular commodity is not enough to satisfy human wants completely. So, if scarcity doesn't exist, it'll mean that everyone's wants will be fulfilled, hence the need to study economics will not be there.
I think the answer is E (sorry if I am wrong)
