acoustic: Having to do with sound or hearing.
adaptation: (in biology) The development of new programs, processes, policies and structures to make communities and their inhabitants better able to head off — or at least withstand — the dangerous impacts of a warming climate. Those impacts may include drought, flooding, wildfires, extreme heat and extreme storms.
amplify: To increase in number, volume or other measure of responsiveness.
anatomy: (adj. anatomical) The study of the organs and tissues of animals. Or the characterization of the body or parts of the body on the basis of structure and tissues. Scientists who work in this field are known as anatomists.

atom: The basic unit of a chemical element. Atoms are made up of a dense nucleus that contains positively charged protons and uncharged neutrons. The nucleus is orbited by a cloud of negatively charged electrons.
baleen: A long plate made of keratin (the same material as your fingernails or hair). Baleen whales have many plates of baleen in their mouths instead of teeth. To feed, a baleen whale swims with its mouth open, collecting plankton-filled water. Then it pushes water out with its enormous tongue. Plankton in the water become trapped in the baleen, and the whale then swallows the tiny floating animals.
biologist: A scientist involved in the study of living things.
blowhole: (in biology) Nostrils on the top of the head of a cetacean (whale, porpoise or dolphin) through which the animal breathes. Toothed whales (like orcas) have one, baleen whales, such as right whales, have a pair.
cell: (in biology) The smallest structural and functional unit of an organism. Typically too small to see with the unaided eye, it consists of a watery fluid surrounded by a membrane or wall. Depending on their size, animals are made of anywhere from thousands to trillions of cells. Most organisms, such as yeasts, molds, bacteria and some algae, are composed of only one…
