1. Scientific Method, Microscope, Chemistry, STERNGRR

2. Scientific Method First step of scientific method is STATE THE PROBLEM
Hypothesis-
A prediction based on research and prior knowledge.
Controlled experiment means
ONLY 1 Variable

3. Microscope Diaphragm Adjusts to let in more/less light to the specimen
How to calculate total magnification-
Eyepiece multiplied by objective
10X * 45X =
450X

4. Chemistry Organic- Contains Carbon and Hydrogen 4 types- Carbohydrates
Lipids (fats)
Proteins
Nucleic Acids

5. Carbohydrates
Quick Energy
Made of simple sugars
Ring shaped structure

6. Lipids Stored Energy and membranes (lipid bi-layer)
Made of Glycerol and 3 fatty acids
Looks like a long letter E

7. Proteins Tissue and muscle growth and enzymes Made of Amino acids
Contains Nitrogen

8. Nucleic Acids Store and transmits Hereditary information DNA and RNA
Nucleotide: Made of Sugar, phosphate, and nitrogen base

9. Enzymes (Biological Catalyst)
Speeds up chemical
Acts on only 1 substrate
Affected by temperature and pH
Are proteins

10. pH pH scale goes from 0 to 14 Acids (BELOW 7) Bases (ABOVE 7)
Neutral (7)
The further from the middle the stronger they are

11. STERNGRR
Synthesis, Transport, Excretion, Respiration, Nutrition, Growth and Development, Reproduction, Regulation

12. Synthesis Taking small pieces and making a large object
Example: Protein Synthesis

13. Transport Moving materials around an organism
Example: Diffusion, Osmosis, Active Transport

14. Excretion
Removal of waste
Exhaling CO2

15. Respiration
Turning Food into ENERGY (ATP)
Cellular Respiration
→ ATP

16. Nutrition
Taking in nutrients

17. Growth and Development
Growth- getting bigger
Development- undergoing changes

18. Reproduction
Asexual – 1DNA source
Sexual- 2 DNA source

19. Regulation
Homeostasis- Keeping an internal balance
