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

Key Terms Active transport: membrane proteins use cellular energy (usually ATP) to move molecules or ions across a plasma membrane against their concentration gradient. Allele: different forms of a gene • genotype – the combination of alleles in an organism. Aquaporin: a specialised channel protein in the plasma membrane of a cell‚ which is selectively permeable to water. Attachment protein: a protein in the plasma membrane of a cell that attaches either to the cytoskeleton inside the cell‚
