Deductive reasoning >

BIG concept applied to specific situation… ex. natural selection applies to virus

Inductive reasoning <

Specific detail used to build BIG concept… ex. Beaks on Darwin’s birds help concept of natural selection

Characteristics of living systems

1. Consists of cells

2. Store and process information DNA

3. Transform

4. Grow and reproduce

5. Adapt and evolve

Cell Theory

• All organisms are composed of living cells

• Cells are the smallest living things

• Cells arise from pre-existing cells

Changing electrons

ION

Change neutrons

ISOTOPE

Change protons

Get new element

Hydrophobic

No partial charge (non polar), avoids water

Hydrophilic

Partially charged (polar), plays well with water

Every step on the pH scale is

tenfold

Lower pH means

higher concentration of hydrogen ions (H+)

If seawater has a pH of 8, and water has a pH of 7, which has more parts hydrogen ions?

Water

How many fold more hydrogen ions does hydrochloric acid (1) have compared to pure water (7)?

1,000,000

Carbohydrate

Monosaccharide

Lipid

Fatty acid

Nucleic acid (DNA)

Nucleotide

Protein

Amino acid

What bond holds proteins together?

peptide bonds

Do prokayotes have organelles?

NO

Do prokaryotes or eukaryotes have a cytoskeleton?

Eukaryotes

Eukaryotes or prokaryotes? Pili

Prokaryotes

Prokaryotes or eukaryotes? Flagella

BOTH

Nucleoid

Prokaryotic, no membrane, DNA in space

Nucleus

Eukaryotic, surrounded by membrane

Nucleolus “hole”us

Eukaryotic, region inside nucleus making RNA structures for ribosomes (stains as holes in DNA because RNA doesn’t pick up same stain as DNA)

Where are lipids made

Smooth ER

Lysosome

digest and break things down
