The Previous Next Access answers to NCERT Class 10 Science Chapter 6 Life Processes Questions Page Number 95 1. Why is diffusion insufficient to meet the oxygen requirements of multicellular organisms like humans? Solution: Multi-cellular organisms like humans have very big bodies and require a lot of oxygen to diffuse into the body quickly in order to meet the oxygen requirement. Diffusion is a slow process which will take a lot of time to circulate oxygen to all the body cells. Because of its slow nature, diffusion is insufficient to meet the oxygen requirements of multicellular organisms like humans. 2. What criteria do we use to decide whether something is alive? Solution: Walking, breathing, growth and other visible changes can be used to determine whether something is alive or dead. However, some living things will have changes that are not visible to our eye; Hence, the presence of the life process is a fundamental c...

Then, according to Snell's law, sin i sin r 1 = μ .....(i) and sin r 2 sin e = 1 μ.....(ii) But, r 1 = r 2 .....(iii) Putting (iii) in (i), we have sin i sin r 2 = μ.....(iv) Multiplying (i) and (iv), we have sin i sin e = 1 or i = e b. After rainfall, the tiny droplets of water present in the atmosphere act as a prism for the rays coming from the Sun. Thus, the sunlight after striking the surface of the droplets gets refracted and dispersed into its seven components as shown in the figure (figure showing just two components). After this, the light rays are subjected to total internal reflection. Then the rays are again refracted when they come out of the water droplet. Hence,rainbow formation is the combined effect of the refraction, dispersion...
