1. Characteristics of Living Things
Section 1.3
Pages 18 & 19

2. 8 Characteristics of Living Things
Are based on a universal genetic code
Grow and develop
Respond to their environment
Reproduce
5. Maintain a stable internal environment 6. Obtain and use material and energy 7. Taken as a group, living things evolve 8. Are made up of cells
Movement?

3. Living things are based on a universal genetic code
DNA is copied from parents to offspring.
This includes the information needed to live, grow and reproduce

4. Living things grow and develop
A single fertilized egg divides again and again
Cell differentiate (cell specialization)
This means the cells look different from one another and perform different functions

5. Living things respond to their environment
Organisms detect and respond to stimuli (stimulus) from their environment
Birds fly south for the winter

6. Living things reproduce
Sexual reproduction
Cells from two parents unite to form the first cell of a new organism
Asexual reproduction
A single organism produces offspring identical to itself

7. Living things maintain a stable internal environment
Organisms need to keep their internal environment relatively stable, even when external conditions change dramatically
homeostasis

8. Living things obtain and use material and energy
All organisms need materials and energy to grow, develop, and reproduce.
Metabolism is a chemical reaction where the material is either built up or broken down

9. Living things as a group, evolve
Over generations, groups of organisms will evolve
Evolution

10. Living things are made up of cells
The smallest unit considered fully alive
Cells can grow, respond to their surroundings, and reproduce.

11. Scientific Attitudes
Section 1.2
Pages 10 & 14

12. Bias
A bias is a particular preference or point of view that is personal, rather than scientific

13. Scientific Attitudes help scientist generate new ideas
Curiosity
Observation makes you wonder…
Often leads to new questions
Skepticism
Question and explore existing ideas and hypothesis
Design new experiments to double check/test it
Open-mindedness
Willingness to accept different ideas that may not agree with their hypothesis
Creativity
To design experiments
Not peer reviewed

14. Big Ideas
Section 1.3
Pages 20-21

15. Evolution
Evolutionary theory is the central organizing principle of all biological and biomedical sciences
Animals evolved into different shapes and sizes (more diverse)
Different structures and functions are more efficient for a certain environment.
Unity and diversity of life: organisms are fundamentally similar at the molecular level, it is used to build different structures

16. homeostasis
The process when living things maintain a relatively stable internal environment

17. Fields of Biology different branches of Biology are interrelated
Section 1.3
Pages 22-23

18. Global Ecology Biotechnology
Scientists are aided by satellite technology and supercomputers.
This helps us understand our global impact, which affects all life on earth
Biotechnology
Scientists try and correct or replace genes in humans, plants, etc. that may be defective

19. DNA is the information and heredity passed on from parent to offspring
Genomics and Molecular Biology
Focus on the study of DNA and other molecules (smallest objects that scientists study) inside cells.
DNA is the information and heredity passed on from parent to offspring
Paleontologists
Study ancient life
Use this information to organize a Tree of Life
