What term describes how something is made, the materials used to make it, and the shape of the item?

Purpose, how you use it, what it does
What happens when the structure of something is changed? Create an example.
Function changes (Ex. If you make a wheel square, it will not roll as efficiently as a round wheel.)
What are the requirements for a living organism?
-Adaptation through Evolution
-Cellular Organization
-Growth and Development
-Heredity
-Homeostasis
-Metabolism
-Reproduction
-Response to Stimuli
Does a rock belong in Living, In-Between, or Nonliving?
Nonliving
Give 3 examples of living organisms.
(Ex. Person, Rose, Butterfly)
What does PMC in PMC Model of Life stand for?
Program, Metabolism, Container
Any living thing uses DNA to program and the ability to reproduce by passing instructions relates to which part of PMC?
P- Program
What does metabolism mean?
Getting + using energy
True or False: The C in PMC stands for container, meaning cells and barriers (cell membrane).

How many levels of organization are there?
13
Give an example of a population.
(Ex. Penguin)
What are the levels of organization and what makes them different?
- Atom - smallest level
- Molecule - 2+ atoms bonded together
- Organelle - Made of molecules, performs tasks
- Cell - Contains many organelles to do tasks
- Tissue - Clusters of cells found in organisms
- Organ - Collections of tissues to perform tasks
- Organ System - Organs working together
- Organism - Multiple organ systems to allow life
- Population - Multiple organisms, same type
- Community - Different species/biotic factors
- Ecosystem - Biotic + abiotic factors together
- Biome - Region home to ecosystems
- Biosphere - All biomes, where life exists
What level of organization comes after organelles?
Cell
What level of organization comes before ecosystem?
Community
Give an example of an organ.
Heart
Is the nucleus a type of atom?
No, it is a type of organelle. (Atom Ex. Sodium)
True or False: A population includes all types of species, biotic factors, and abiotic factors.
False
What determines if something is a molecule?
2 or more atoms bonded together
What level of organization does the digestive system belong in?
Organ System
True or False: The Earth is a biosphere.
False. The places in which life exists are biospheres.
What do ecosystems make up?
Biomes
What includes biotic and abiotic factors?
