List the 7 most widely accepted characteristics of living organisms - ANSWER ✔✔ Order,
evolutionary adaptation, regulation, energy processing, growth and development, response to the
environment, and reproduction
Describe evolutionary adaptation and give an example - ANSWER ✔✔ refers to smaller, genetic
changes that allow for better survival of an organism. An example would be camouflage because
if an animal can camouflage with their environment they will ideally live longer and be able to
further reproduce more.
What is an adaptation? What characteristic of life would an adaptation fall into? - ANSWER ✔✔

Asexual Reproduction - ANSWER ✔✔ Gives rise to a new offspring from a single organism
A group of one particular species living within defined boundaries of a community best describes
what - ANSWER ✔✔ Population
A system of living and non living things in a region best describes a what - ANSWER ✔✔
Ecosystem
What are the three domains that comprise the Linnaean Classification system - ANSWER ✔✔
Archaea, Eubacteria, and Eukarya
What is the purpose of a phylogenic tree? - ANSWER ✔✔ A branching diagram that shows the
relationship between different levels of Linnaean classification taxa. Each branch point
represents where the two organisms likely share a common ancestor
True or false: Extremophiles are a small sub-set of the Archaea domain that live in extreme
environments - ANSWER ✔✔ True
Bacteria that neither benefit from nor harms the host are often part of the human flora are
considered what - ANSWER ✔✔ Commensal
