Properties of Life (Exam 1)

First Exam of the Year

Atom

Smallest unit of matter

Molecule

A number of atoms bound together

Cell

Smallest Unit We consider to be alive

Tissue

A number of cells that are similar and have the same function

Organ

Multiple Tissues that work together to accomplish bigger tasks

Organ System

Multiple organs with coordinated effect

Organism

A living thing

Population

Organisms , same species , living together

Community

Multiple populations living with each other

Ecosystem

Community and abiotic environment

Biosphere

Inhabited by all living things on Earth

Metabolism

The sum of chemical reactions in a organism

Homeostasis

Keeps peace in the body

Adaptations

Traits that help an organism survive + reproduce ( due to evolution )

Taxonomy

Science of classifying, describing and naming organisms

Phylogenic Tree

Tool used to show relationships and evolutionary pathways between organisms

Systematics

An attempt to find relationships between organisms

Protists

( Made up of several kingdoms ) complex single celled organisms that photosynthesize or ingest food

Kingdom Fungi

Molds, mushrooms, and yeast

Kingdom Plantae

Multicellular and photosynthesize (plants)

Kingdom Animalia

Multicelluar and digest food ( Animals )

Intelligent design

Theory that organisms are two complex to have evolved themselves

Uniformitarianism

The Earth changing geologically over long periods of time

Biogeography

The study geographic distribution of organism

Colonization

Introduction to a new species ( Flying, swimming, or raft )

Adaptive Radiation

Ancestral organisms diversifying rapidly

Niche

Role to play in a economical stand

Parsimony

Minimizing the number of evolutionary events

Ancestral Traits

Traits passed down

Clade

A group of organisms who share a common ancestor

Derived traits

Arrived during evolution

Island tameness

When animals evolve without fearing anything

Fitness

How many offspring an organism has that survive and reproduce

Homologous Structures

traits due to sharing a common ancestor

Analogous

traits not similar due to sharing a common ancestor

Vestigial Structure

Structure with little to no use

Selective Breeding

Only breeding organisms with favored traits

Natural Selection

When traits that increase survival and mating chanced

Heritable

Able to be passed down to offspring

Exponential Growth

Increasing by a specific proportion each generation

What are the Properties of life?

Responsiveness, producing offspring and processing matter and energy

Who is the Creator of Taxonomy “To Discover God’s order”

Carl Linnaeus

Archaea and Bacteria are?

Prokaryotes

Multicellular Organisms

Eukaryotes

Why does Intelligent design suck?

Not testable and no natural explanation

Charles Darwin

We know that organisms have a long history of evolution and gain adaptations over time thanks to.

Because of Charles Lyell we know that

Geological formations are results that happened slowly overtime
