Document Summary
Bi110-lecture 3-evolution of life and earth (cont"d) & energy and matter (module 2) Adenosine triphosphate---po4^3- removed (energy released)---adenosine diphosphate---po4^3- added (energy added from nutrients)--- atp. Gene similarity between humans and chimpanzees: 96% Humans differ to each other by 1% The theory of evolution is the cornerstone of modern scientific understanding of life. Concept of biological evolution originally proposed by darwin. Evolution is the core theme in biology. Evolution requires genetic diversity in population and environmental conditions that promote fittest of certain individuals. All tangible substance are made of matter. Can take into many forms: electromagnetic radiation (visible and uv light), chemical energy and kinetic energy. Gamma rays (shortest wavelengths in nm = higher energy) Visible light (from 400 nm to 700 nm) Definition: electromagnetic radiation that humans can detect with their own eyes (also a wave of discrete particles called photons)
