intermediate

In the 2010s, a series of intermediate species called darwinopterans were found that revealed that the head and neck had changed first before the rest of the body.

This facilitates the reaction of the intermediates with each other to make a polyester, which gels into solid particles that can easily be separated out.

This nighttime relief is most effective in cities with intermediate and wet climates, according to the study.

The team used electrocatalysis, a type of chemical reaction initiated by electron transfers to and from reactants on surfaces of catalysts, to convert carbon dioxide into biocompatible intermediates, such as acetate and ethanol.

Skill level: Geared toward beginner and intermediate walkers, although some walks can be more challenging if the group is willing, Murillo said.
