Graduate students monitoring the benthic organisms of a freshwater lake take samples at different depths throughout the lake and identify the invertebrate species present. In a deep region of the lake, they discover a crustacean that appears to be a new species. They decide to study its natural history. What is the first thing they should do in this study?

Do a literature search to find natural history information on closely related species.

Explanation:

In the context,  few graduate students monitored the benthic organisms from the fresh lake water samples and identified the invertebrate species that are present.

They also discover a crustacean which appears to be the new species for which they decided to do a study on its natural history. The first thing that the graduate student should do is to do a literature search for finding a natural history on the information that are closely related species.

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
