Biology Vocabulary: 1. Immigration: influx of individuals into an area 2. Emigration: movement of individuals out an area. 3. Logistic growth: (shown with an S-shaped curve) population growth that levels off at carrying capacity. 4. Exponential growth: (shown as J-shaped curve) geometric increase of a population as it grows into an ideal unlimited environment. 5. Niche: the sum total of a species use of the abiotic and biotic resources in its environment 6. Symbiosis: an ecological relationship

theory states that: i. All organisms are made of organelles / cells. ii. All existing cells are produced by other living / dead cells. iii. The atom / cell is the most basic unit of life. 7. Cell theory is one of the great unifying theories of biology / chemistry. Main idea: Prokaryotic cells lack a nucleus and most internal structures of eukaryotic cells. 8. For each of the following cell characteristics‚ place a check mark in the appropriate box or boxes to indicate whether it is a characteristic

CHOLERA Causes: (reference 10) Cholera is a small intestinal infection caused by the digestion of the bacterium Vibrio Cholerae (a comma-shaped bacillus that varies in size from 1-3 µm in length by 0.5-0.8 µm in diameter)‚ present in food or water (raw shellfish‚ uncooked fruits and vegetables‚ and other foods). The disease is most common in places with poor sanitation‚ crowding‚ war‚ and famine. Transmission: (reference 1) When humans ingest cholera bacteria‚ they may not become sick themselves
