 Human Eye Cataract RAINBOW FORMATION THROUGH PRISM               Tyndall Effect  Activity 11.3 1. What is meant by power of accommodation of the eye? Answer- The ability of the lens of the eye to adjust its focal length to clearly focus rays coming from distant as well from a near objects on the retina, is known as the power of accommodation of the eye. 2. A person with a myopic eye cannot see objects beyond 1.2 m distinctly. What should be the type of corrective lens used to restore proper vision? Answer- An individual with a myopic eye should use a concave lens of focal length 1.2 m so that he or she can restore proper vision.   3. What is the far point and near point of the human eye with normal vision? Answer- The minimum distance of the object from the eye, which can be seen distinctly without strain is called the near point of the eye is. For a normal ...

  Mendel's Law of inheritance Activity 9.2 Green & Yellow Pea breeding can be used to show TT Tt tt are in 1:2:1 ratio. F1 progeny are used to generate F2 progeny by self-pollination Breeding of Peas Cellular DNA is the information source for making proteins in the cell. A section of DNA that provides information for one protein is called the gene for that protein. Plant height can depend on the amount of a particular plant hormone . The amount of the plant hormone made will depend on the efficiency of the process for making it. Consider now an enzyme that is important for this process. If this enzyme works efficiently, a lot of hormone will be made, and the plant will be tall. If the gene for that enzyme has an alteration that makes the enzyme less efficient, the amount of hormone will be less, and the plant will be short. Thus, genes control characteristics, or traits. Genes  are small  sections of DNA  within the genome that code for proteins. They contain t...
