Study Notes

Characteristics of Life

Homeostasis involves maintaining a constant internal environment
Adaptation involves the ability to adapt to the environment

Levels of Organization

The smallest unit of life is a cell, contained within a plasma membrane
A group of similar cells performing a specific function is called tissue
A structure composed of more than one tissue is called an organ
A group of organs performing a broad biological function is called an organ system
The natural hierarchy of biological organization is: cell → tissue → organ → organ system

Taxonomy and Classification

Taxonomy is the science that deals with the study of all living things
Artificial classification in biology uses characteristics to identify and group organisms
Natural organization in biology emerges from evolutionary relationships
The purpose of taxonomy in biology is to understand and classify living organisms
Humans are considered as Homo sapiens
The correct order of taxonomy for modern humans is: Domain: Eukarya, Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Primates, Family: Hominidae, Genus: Homo, Species: Homo sapiens
The taxonomic level that includes ONLY Homo sapiens (modern day humans) is Species

Homeostasis

Homeostasis is the maintenance of a constant internal environment
In humans, body warmth is maintained through homeostasis
The meaning of 'homeostasis' in Greek is "remaining the same"
