Study Notes
Cell Biology
-
Cell Structure:
- Prokaryotic vs. Eukaryotic cells
- Organelles function (nucleus, mitochondria, ribosomes, etc.)
-
Cell Membrane:
- Structure: phospholipid bilayer, proteins
- Functions: selective permeability, communication, signaling
Genetics
-
DNA Structure:
- Double helix, nucleotide composition (adenine, thymine, cytosine, guanine)
-
Gene Expression:
- Transcription (DNA to mRNA)
- Translation (mRNA to protein)
-
Mendelian Genetics:
- Laws of segregation and independent assortment
- Genotype vs. phenotype, homozygous vs. heterozygous
Evolution
-
Natural Selection:
- Variation, competition, survival of the fittest
-
Speciation:
- Allopatric and sympatric speciation
-
Common Ancestry:
- Evolutionary tree, evidence from fossils, comparative anatomy
Ecology
-
Ecosystems:
- Biotic (living) and abiotic (non-living) components
- Energy flow (food chains and food webs)
-
Population Dynamics:
- Factors affecting populations: birth/death rates, carrying capacity
-
Biomes:
- Types: tundra, rainforest, desert, grasslands, aquatic
Physiology
-
Human Body Systems:
- Major systems: circulatory, respiratory, digestive, nervous
- Homeostasis and feedback mechanisms
