Difference between meiosis and mitosis |
| Answer» Mitosis\tInvolves one\xa0cell division\tResults in two daughter cells\tResults in\xa0diploid\xa0daughter\xa0cells\xa0(chromosome\xa0number remains the same as parent cell)\tDaughter cells are genetically identical\tOccurs in all organisms except viruses\tCreates all body cells (somatic) apart from the\xa0germ cells\xa0(eggs and sperm)\tProphase is much shorter\tNo recombination/crossing over occurs in prophase.\tIn metaphase individual chromosomes (pairs of chromatids) line up along the equator.\tDuring anaphase the sister chromatids are separated to opposite poles.Meiosis\tInvolves two successive cell divisions\tResults in four daughter cells\tResults in\xa0haploid\xa0daughter cells (chromosome number is halved from the parent cell)\tDaughter cells are genetically different\tOccurs only in animals, plants and fungi\tCreates germ cells (eggs and sperm) only\tProphase I takes much longer\tInvolves recombination/crossing over of chromosomes in prophase I\tIn metaphase I pairs of chromosomes line up along the equator.\tDuring anaphase I the sister chromatids move together to the same pole. | |

Why is evaporation is called surface phenomena ? |
|
Answer» Bcauz. Only the particles at liquid surface has higher kinetic energy and are able to break away from the forces of attraction of other particles and get converted into vapours Evaporation is known as surface phenomenon . We can say this with an example: take a glass of water and put it under sun at the same time pour water on the floor from the 2 nd beaker , the water in the 1 st beaker gets slowly evaporated as only the molecules in the 1st row 1st get evaporated where as if pored down there\'s only 1 layer of water so the molecules get evaporated quickly |
