A scientist has correctly gone through all the possible steps in a dichotomous key, but has not identified an insect. Which most
likely describes why he did not identify the insect? The scientist must have made a mistake. The insect might be an unknown variation or a new species. The organism evolved during identification. The dichotomous key had too many questions.
The insect might be an unknown variation or a new species.
<h3><u>Explanation;</u></h3>
A dichotomous key is a biological tool that is used by scientists to identify unknown organisms. It is used to identify organisms in an ecosystem such as trees, mammals, fish, etc.
<em><u>Dichotomous key consist of a series of steps or statements about a specific characteristics of organisms that leads to the correct name of a given organism.</u></em>
<em><u>If the scientist went through all the possible steps correctly in a dichotomous key and was unable to identify the insect, it means the insect might have been unknown variation or a new species.</u></em>

A proximate cause is an event which is closest to, or immediately responsible for causing, some observed result. This exists in contrast to a higher-level ultimate cause (or distal cause) which is usually thought of as the "real" reason something occurred.
Eutrophication is where these nutrient rich compounds mix with nearby water sources and promote the growth of large amounts of algae. Algae go through respiration and take up the dissolved O2 in water which causes these areas to experience low O2 levels. Everything needs O2 to survive thus nearby organisms and plants die out creating dead zones.
