Air pollution and its health impacts on three cities Air pollution has a significant impact on human health. It can cause death by compromising the respiratory and cardiorascular system‚ or by its toxic carcinogenic effects. Transport is the greatest source of air pollutions‚ owing to increased numbers of cars in the city. Moreover‚ manufacturing and factories are another reason for air pollution.

contributed to theories involving light. Of these‚ the wave-particle duality is arguably the most strange and noteworthy concept in the field. Throughout history‚ some physicists have argued that light behaves as a wave‚ such as Christiaan Huygens and others‚ such as Isaac Newton have proposed that light consists of particles (Wave-Particle Duality‚ March 2010). Today‚ as stated in the wave-particle duality‚ light is said to exhibit wave-like and particle-like properties. And still today‚ physicists are troubled

(water only) 2) Active a) Molecules b) Particles Diffusion Diffusion is the net passive movement of particles (atoms‚ ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. It continues until the concentration of substances is uniform throughout. Some major examples of diffusion in biology: • Gas exchange at the alveoli — oxygen from air to blood‚ carbon dioxide from blood to air. • Gas exchange for photosynthesis — carbon dioxide from air to leaf
