Chapter 1 Introduction To Science Flashcards
The Properties of life that all must be fulfilled
1) reproduction capability
2) ability to grow and develop as instructed by dna
3) energy use
4) complex structure and order
5) composed of cells (at least one)
6) homeostasis
7) evolution
Is a virus a living thing?
No.
Why isn’t a virus a living thing?
It is not composed of cells and cannot reproduce on its own.
What is the smallest unit that shows the effect of evolution?

3) community (all interacting living populations in an area)
4) organism (an individual)
5) organ system (a group of organs that work together, like the circulatory system)
6) organ (consists of multiple tissues cooperating to perform a task)
7) tissue (interacting group of similar cells that make up a vital part of an organ)
8) cell (the fundamental unit of life)
9) organelle (component of cell w a specific function)
10) molecule (group of atoms bonded together)
11) atom (fundamental unit of matter)
What is an example of a single-celled organism?
bacterium
What are atoms made of?
Subatomic particles
What is the level of life’s organization is the smallest one that can be considered alive?
The cell.
What does the scientific method aim to do?
Discover and explain.
discover science
Learning about the natural world by making verifiable observations, taking measurements, gathering data, and performing tests.
what is the origin of the word “science”?
Latin ‘scire’ ‘to know’
What are the steps of the scientific method?
- Observation
- Question
- Hypothesis
- Experiment
- Results
- Conclusion (more Questions)
- New Hypothesis (?)
hypothesis
A proposed explanation for an observation
theory
a well-substantiated explanation that is much broader in scope than a hypothesis.
