Asymmetry

• Lack of symmetry

• Perfect balance

• Equal proportions

• Symmetrical arrangement

Binomial nomenclature

• A system developed by Linnaeus for naming species using two words — the genus name and a descriptive name

• A method for classifying animals based on their habitat

• A technique for determining the age of fossils

• A way to categorize plants based on their color

Dichotomous key

• A tool used for measuring temperature

• A diagram used to classify things, by grouping them into smaller and smaller groups based on choosing one of two features

• A method for calculating the area of geometric shapes

• A type of key used to unlock doors

Microscopy

• The study of light and its properties

• The use of microscopes to view structures that can't be seen with the naked eye

• A technique for measuring the size of small objects

• The process of creating images using sound waves

Prions

• Infectious proteins that can cause disease

• Bacteria that cause infections

• Viruses that attack cells

• Fungi that decompose organic matter

Endotherm

• An animal that can maintain its internal body temperature in a constant range

• An animal that relies on external sources for body heat

• An animal that can survive in extreme cold environments

• An animal that has a fluctuating body temperature

Vertebrates

• Animals with backbones

Viroid

• The smallest infectious known pathogen, comprised solely of a short single-stranded piece of RNA

Species

• A group of organisms that can only reproduce in captivity

• A group of organisms with many features in common and can mate with each other to produce fertile young under natural conditions

• A classification of organisms based solely on their habitat

• A collection of organisms that are all genetically identical

Poikilothermic

• Having a constant body temperature regardless of the environment (as in warm-blooded organisms)

• Having a body temperature that fluctuates and is similar to the temperature of its environment (as in cold-blooded organisms)

• Being able to regulate body temperature through behavioral means (as in some reptiles)

• Maintaining a body temperature that is always lower than the surrounding environment
