Biology 2 Summary Biology 2 Summary Cellular Basis of Tissue and Cell Culture: Based on the principle of chromosome duplication and equal segregation during mitosis. Photosynthesis Intensity: Plant leaves absorb all light wavelengths except green, therefore photosynthesis intensity is weakest in the green light region. Analyzing Cross Results: Phenotype ratio of F1: 3:3:1:1 can be…

Biochemistry Practical 3: Glucose Quantification Biochemistry Practical 3: Glucose Quantification Biochemistry Practical 3: Glucose Quantification 1. Principle: Direct Proportionality: Absorbance (E) is directly proportional to the concentration (C) of the substance. Dilution: The photometric method applies the formula: Ct = (Et/Ec) x Cc x V/Vt. GOD (Glucose Oxidase): Glucose quantification using the enzyme method relies…

Basic Concepts of Immune Response Basic Concepts of Immune Response Basic Concepts of Immune Response Immune response is the body’s ability to recognize, respond to, and eliminate foreign substances (antigens). Innate immunity is the body’s inherent, genetically determined ability to defend itself. Sensitization is the process by which the body comes into contact with a…
