2. a group of closely related species is called a ____________.
3. organisms are classified based on ____________ relationships and shared characteristics.
4. dna and molecular evidence are used to improve ____________ systems.
5. common names are not reliable because they can vary by ____________.
6. a method of studying populations by counting individuals in small representative areas is called ____________ sampling.
7. in ____________ sampling, researchers lay out a line and record organisms along it.
8. ____________ sampling involves capturing, marking, releasing, and recapturing organisms to estimate population size.

Explanation:

1. In taxonomy, the Kingdom is the broadest category.
2. A genus is a group of closely related species.
3. Organisms are classified based on evolutionary relationships and shared characteristics.
4. DNA and molecular evidence are used to improve classification systems.
5. Common names can vary by region, so they are not reliable.
6. Quadrat sampling involves counting individuals in small representative areas.
7. In line - transect sampling, researchers lay out a line and record organisms along it.
8. Mark - recapture sampling involves capturing, marking, releasing, and recapturing organisms to estimate population size.
