What is life science?
The study of living things (or organisms)
What are the four parts of the grand narrative of a biblical worldview?
Creation, Fall, Redemption, Restoration
What is taxonomy?
Sorting organisms into groups
What does unicellular mean?
Made of ONE cell
What is homeostasis?
Homeostasis is the ability of an organism to maintain internal stable conditions.
What is qualitative data and what is quantitative data?
Qualitative = uses words and descriptions
Quantitative= numbers and measurements
What is naturalism?
The worldview that proposes that living things come from natural processes with no creator. It teaches that science is the authority on truth.
Why do scientists classify living things?
It helps scientists understand organisms better, helps us understand the variety of life in the world, and helps us manage creation and fulfill the creation mandate.
What does multicellular mean?
Made of MANY cells
What are the characteristics of life?
made of cells, need energy, reproduce (sexually or asexually), respond to stimuli, grow and develop.
-can also maintain homeostasis and have genetic information
What is a control group?
A group of cells allowed to grow without any new chemicals or treatments.
What is a worldview?
The overarching narrative that a person uses to see and interpret the world
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
What is the difference between eukaryotic and prokaryotic cells?
Eukaryotic cells DO have a nucleus
Prokaryotic cells have NO nucleus
Why is homeostasis important?
It is essential for keeping an organism alive and allowing it to function properly
What is a hypothesis?
An idea or possible explanation that can be tested.
What does it mean that humans are made in the image of God?
Humans are uniquely made and have the ability to: plan and reason, experience emotions, create and love, be loved, have a sense of eternity

Give an example of homeostasis.

Variables
Independent (things we change)
Dependent (things that CAN change indirectly but that are being watched or measured)
What is the creation mandate?
God's command for humans to fill the earth and have dominion over it.
What two parts make up an organism's scientific name?
Genus and Species
Why isn't a stalactite considered alive even though it grows?
A stalactite is not made of cells. It does not need energy, does not reproduce, does not pass down information, and does not respond to stimuli.
