|
Answer» Due to ABA means abscisic acid Autumn is the time for trees to get prepared for the summer. Leaves act as high functioning engines in a tree and they provide energy and food support to the trees. The old leaves those lasted for a year have lesser efficiency or got damaged due to several reasons. So the trees change their engines or say leaves once a year to make their life-cycles smooth. As the summer is very hard time due to less water, high temperature and wind storm, trees prepare themselves for that. Evaporation of water from leaf surface is important during summer and old leaves may have jammed pores and for that trees renew their leaves in Autumn. |

Why metallic property decreases across a period while increasing Along a group |
| Answer» Metallic character decreases as you move across a period in the periodic table from left to right. This occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell. Metallic character increases as you move down an element group in the periodic table because atomic size increases. | |

Evolution should not be equated with progress.justify |
|
Answer» Evolution should not be equated with progress. In fact, there is no real \'progress\' in the idea of evolution. Evolution is simply the generation of diversity and the shaping of the diversity by environmental factors. The only progressive trend in evolution seems to be that more and more complex body designs have emerged over time. However, again it is not as if older designs are inefficient! So many of the older and simpler designs still survive [..] In other words, human beings are not the pinnacle of evolution, but simply yet another species in the teeming spectrum of life. Evolution is simply the generation of diversity and the shaping of the diversity by environmental selection.Species adapt to the conditions available in their environment. Some older and simple species live on quite effectively. The only progressive trend in evolution seems to be that more and more complex body designs have emerged over time.In fact, one of the simplest life forms like bacteria -- inhabit the most inhospitable habitats like hot springs , deep sea thermal vents and the ice in Antarctica.This is the reason why evolution is not equated with progress. |

Names which are given on this basis are popularly known as IUPAC name. The rules for nomenclature are as follows:Identify the number of carbon atoms in carbon compound. Name the carbon compounds according to the number of carbon atoms.Example:\xa0Saturated hydrocarbon having one carbon atom is named as Methane. Saturated hydrocarbon having two carbon atoms is named as Ethane.Unsaturated hydrocarbon with double bond having two carbon atoms is named as Ethene.Unsaturated hydrocarbon with triple bond between carbon atoms is named as Ethyne. | |
