Regulation of internal environment
Growth and development
- Energy is actively taken in from the
Response to the environment
- Reproduction-ability to faithfully replicate
- new generations
- Evolution-ability of populations to
- change generations
What are the
hierarchical levels that biologist study and how do they relate to each other?
Molecular-cluster of atoms
- Cell-smallest unit of living matter
- separated by membrane
- Tissue-group of similar cells with
- specialized function
- Organ-group of different tissues that
- have a specific function
- Organ System-group of organs with a
- specific function
Organism-an individual living thing
- Population-a group of interacting individuals
- of the same species
- Community-the populations of species
- in an area which interact in some way
- Ecosystem-community of living
- organisms and the physical components of the environment for a given are
- Biosphere-all environments that
- support life on earth

- It's the property where living things become more and
- more complex as it goes from cellular level (exp humans are made of cells) to

How are living
things classified into domains, and is domain a more inclusive or less
inclusive grouping than a kingdom?

difference between discovery science and hypothesis-driven science?

- observation that produces a general conclusion or idea
- Hypothesis-driven science begins with
- a question or a problem that can be tested
How does the
Scientific Method work?
- IF TEST SUPPORTS HYPOTHESIS: make
- additional predictions and test them
- IF TEST DOES NOT SUPPORT HYPOTHESIS:
- revise hypothesis or pose a new one
How does theory
differ from hypothesis?
- Theory have been tested, where hypothesis can be
What is a
testable hypothesis & and falsifiable hypothesis?
- Testable hypothesis is a hypothesis
- that can be tested
- Falsifiable hypothesis is a hypothesis
- that can be disproven by experimentation
