Cells are the basic components of all living things. Some living things are unicellular, like bacteria, others are multi-cellular, like humans.

All living things reproduce, by either asexual or sexual means.

Living organisms inherit traits from the parent organisms that created them.

Living things require energy, usually in the form of ATP. They use this energy to carry out energy-requiring activities such as metabolism and locomotion.

All living things respond to stimuli in their environment.

All living things maintain the state of internal balance.

Living things adapt to their environment and evolve.

Life is defined as any system capable of performing functions such as eating, metabolizing, excreting, breathing, moving, growing, reproducing, and responding to external stimuli.

All organisms capable of breeding freely with each other under natural conditions.

• Binomial Nomenclature also known as Linnaean system of classification • 1st name is the Genus which is capitalized, in italics(or underlined) • 2nd name is the species which is not capitalized, in italics(or underlined)

The science of classifying all organisms, taxonomists classify both living and fossil species

• appearance • how they reproduce • diet • cellular structure • method of movement • physical structures • heredity information etc. ..

• Kingdom • Phylum • Class • Order • Family • Genus • Species

The study of evolutionary relatedness between, and among species; shown using a phylogenetic tree. Can be used to create a dichotomous Key.

yes, family is a sub-group of a class.

Not always, many orders can be present in a phylum.

Biology is the study of living things and things that were once alive and how they interact with the matter and energy around them.
