The temperature of the surface of the Arctic Ocean is fairly constant, near the freezing point of seawater. Because the Arctic Ocean consists of saltwater, the temperature must reach −1.8 °C (28.8 °F) before freezing occurs.
Biomolecules: carbohydrates, lipids, proteins, and nucleic acids
Monomer: building block
Lipids: fatty acid and glycerol
Blubber: is a thick layer of fat, also called adipose tissue, directly under the skin of all marine mammals.
Blubber covers the entire body of animals such as seals, whales, and walruses—except for their fins, flippers, and flukes.
Blubber an important part of a marine mammal's anatomy.
An ecosystem is a community made up of living organisms and nonliving components such as air, water, and mineral soil. Ecosystems can be studied in two different ways. They can be thought of as interdependent collections of plants and animals, or as structured systems and communities governed by general rules

Endothermic: Generating internal heat to moderate body temperature, examples: modern birds and mammals.
Ectothermic: Relying on the environment and behavior to regulate body temperature, typical reptiles.
Mesotherm: intermediate to cold-blooded ectotherms and warm-blooded endotherms, examples: shark, echidna
Red Blood Cell: A type of blood cell that is made in the bone marrow and found in the blood. Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body.
People frequently ask if penguins and puffins are related.
Although both are birds that share a similar black and white feather coloration and a love of fish for breakfast, penguins belong to the family Spheniscidae, and puffins belong to the family Alcidae.
Taxonomy: is the science of defining and naming groups of biological organisms on the basis of shared characteristics. Kingdom, Phylum, Class, Order Family, Genus, Species
Melanocytes have melanosomes which produce melanin by the oxidation of tyrosine using and enzyme called tyrosinase
The melanosomes are transported to keratinocytes to induce pigmentation in hair.
Hair is made of keratin, the protein
These cells were found in the penguin fossil
