Active Transport - When a substance moves against/up a concentration gradient, from a region where they are of lower concentration to a region where they are of higher concentration. Adaption - Any characteristic of an organism that improves its chances of surviving in its environment. Aerobic respiration - Respiration with oxygen. Anaerobic respiration - Respiration without oxygen. It releases less energy than aerobic respiration. Alleles - Different forms of a gene which occupy the...
