What r limitations of dobreiner law of classification? |
| Answer» Limitations of Dobereiner\'s classification: Dobereiner could find only three triads; .i.e total of 9 elements only. However the total number of elements were more than that of those encompassed in Dobereiner\'s Triad. Thus,Dobereiner\'s could not be classify most of the elements known at that time.This was a major drawback of Doberenier’s triads.He stated that when three elements of same chemical properties were arranged in order of their increasing atomic masses, the sum of first and third element was rougly the average of the middle element. But, three elements nitrogen, phosphorus and arsenic have same chemical properties, but these three elements do not follow Doberenier’s rule.Atomic mass of nitrogen is 14 u and that of arsenic is 74.9 u but their average is 14+74.9/2= 44.45 u which is much higher than atomic mass of phosphorus i.e, 31 u. | |

\'Variations are beneficial for species\'Explain. |
| Answer» Variations are beneficial for species. A variation suitable for the particular niche is selected by nature in evolution. Thus variations are necessary for the survival of the species. Variation is important for evolution of the species. E.g.: A population of heat resistant bacteria in temperature of the water survives, if the temperature of water increases by global warming but most other bacteria would die.Variations are beneficial for the survival of the species. Populations of organisms fill well-defined places, or niches, in the ecosystem, using their ability to reproduce. However, niches can change because of reasons beyond the control of the organisms and could even wipe out the entire population. However, if some variations were to be present in a few individuals in these populations, there would be some chance for them to survive.For example - If there were a population of bacteria living in temperate waters and suppose the water temperature were to be increased by global warming. Most of these bacteria would die, but the few heat resistant variants would survive and grow further. Variation is thus useful for the survival of species over time. | |

If the fore finger represents the direction of the field and the second finger that of the current, then thumb gives the direction of the force. |

What is advance sunrise and delayed sunset? |
| Answer» Due to refraction:The light rays through vacuum and then through the atmosphere of the earth and then it is finally seen by us. Vacuum will be a rare medium and the earth’s atmosphere with all its temperature changes, winds, different gases, will be a denser medium in comparison. Bending of light occurs.During sunrise, when the sun is just below the horizon, our atmosphere causes the light rays to bend and we see the sun early. Similarly, at sunset, the apparent position of the sun is visible to us and not the actual position due to the same bending of light rays effect. Due to refraction we see the sun rise about two minutes before it’s actually there and during sunset we see it for around two minutes more, even though it has already moved from that position. | |

What is importance of stomata in plants |
|
Answer» Simple answer .....exchange of gases The gas exchange occurs when stomata are open and facilitates photosynthesis. Photosynthesis is the process by which plants convert sunlight into usable energy. During photosynthesis, carbon dioxide is taken in from the atmosphere through the stomata and oxygen is released as a waste product. Both photosynthesis and the gas exchange that powers it are essential to the plant\'s survival. Stomata provides a way to leaf to exchange co2 or o2. And for transpiration also |
