1. Ask a question (based on observation)2. Form a hypothesis (inference or
prediction)3. Set up a controlled experiment4. Record and analyze results5. Draw a conclusion
The Scientific Method
No… Rocks are considered non-living matter.

The _____ is the basic unit of life.
1. All Living Things Are Made of Cells
MulticellularOrganisms
UnicellularOrganisms
All living organisms make other organisms like themselves reproducing in two ways:
Asexual reproduction-
Sexual reproduction-
2. All Living Things Reproduce
Single celled organisms reproduce this way. The cell divides creating an exact replica of
itself.
Asexual reproduction produces traits the same as the parents.
Two separate organisms unite to produce an offspring.
Sexual reproduction produces traits different from the parents
This is an advantage as it creates a genetic diversity to assure survival of the species.
DNA
Inherit traits from the parents
A segment of material with instructions for one trait
is called a ________.
3. All Living Things Are Based on a Universal Genetic Code
gene
Grow larger
Differentiation of cell types
4. All Living Things Grow and Develop
To grow and develop
Metabolism- chemical reaction in which an organism breaks down material
5. All Living Things Obtain & Use Materials & Energy

______________ use energy from sunlight or chemicals to make their own food. (green plants use photosynthesis)
______________ get their energy by consuming other organisms.(animals and most bacteria)

6. All Living Things Respond to Their Environment

Must be ok on the inside
Homeostasis- process by which an organism keeps its internal conditions stable
7. All Living ThingsMaintain a Stable Internal Environment
If body temp drops too low,“shivering” produces heat to warm you up.
If temp is too hot, “sweating” cools you down.
FEEDBACKHOMEOSTASIS involvesinternal __________ mechanisms
Living things evolve
