How does water drops acts like a prism in nature ? |
|
Answer» The rain drops act like a prism because when the rays of sun falls on ? it distribut the light in seven different colours Actually raindrop itself has two media:1.water 2.air in dropHence when light enters raindrop,it faces refraction twice that leads to splitting of white light in spectrum. This spectrum can be observed as rainbow on large scale.Hence in this way raindrop works like a prism When the sunlight enters from the air to the water droplets it gets refracted internally which results in the spilting of the light into its seven colour components. This is how tiny water droplets acts as prism in the formation of a rainbow. Rainbow |

What is the ph of human teeth |
|
Answer» 5.5 It is in between ph 5.5 Presence of acid decrease pH 5.5 of the mouth cavity and tooth decay starts.☑ The pH scale goes from 1 to 14, with a pH of 1 being the most acidic, and 14 being the most alkaline. A pH of 7 is neutral – the pH of pure water is very close to 7. At a pH of 5.5 the teeth begin to demineralize, putting them at risk for cavities. A healthy mouth is in a neutral pH range. |

Explain why the rate of photosynthesis in plants is low and high temperature |
| Answer» Photosynthesis is an enzymatic process. The enzymes function within an optimum range of temperature which is neither very low nor very high. At low temperature the activity of enzymes is lowered due to which the rate of photosynthesis is also low. Again when the temperature is very high, the activity of enzymes decreases which leads to low rate of photosynthesis. | |

What is isomerism and isomars |
|
Answer» Isomers are molecules with the same empirical formula but a different molecular structure, which takes on various forms:Structural isomerism, where the molecules have the same formula but different bonding patterns and atomic arrangements, e.g. pentane (C5H12) exists as three isomers; n-pentane, where the carbon chain has no branches, isopentane (2-methylbutane) where there is a methyl group branching from the second carbon atom and neopentane (2,2-dimethylpropane) where there are two methyl groups attached to the second carbon atom.Stereoisomerism, where the bonding arrangements remain the same, but the spatial arrangements of functional groups are different. This can take the form of optical isomerism, in which molecules form mirror images of each other based on arrangements around a chiral centre (an atom that has a number of different functional groups bonded to it, all unique); these isomers share physical properties except for interactions with polarised light. An infamous example is thalidomide, which when manufactured exists as a mixture of the left and right handed isomers. Only one of the isomers had the required effect (the sedative effect), the other had practically no sedative effect but was teratogenic (adversely affected the foetus).Isomerism is the tendency of some molecules to behave in this manner.

Differentiatebetween trypsin and pepsin |
|
Answer» Actually pepsin breaks protein into peptones and proteoses . And tripsin acts on protein +peptones+proteoses and convert it into peptides Yes kalpana u r half right?
