Evolution of eyes of humans had happened but why didn\'t it happen with that of planaria |
|
Answer» It is not necessary that everything evolve . Evolution is caused due to differences in dna copying . Planaria have asexual mode of reproduction which causes very less chances of any difference in dna copying whereas in human sexual reproduction cause alot of differences so evolution is much faster....Maybe planaria can also get eyes if u wait for 9999999999999yrs ?? The early design of rudimentary eyes in the form of eye-spots was observed in Planaria which belongs to phylum Playhelminthes. Random changes created a depression in the light-sensitive patch making the vision sharper in animls like planaria.In insects, the light-sensitive spot gradually evolved into special layer with structures like ommatidia.Later, over a period of time, lens was formed in front of the eye. Vertebrates and octopuses developed the eye resembling a pin-hole camera wherein nerve fibres passed in front of the retinaFollow me @[email\xa0protected] |

How is tissue cullure donr |
| Answer» Tissue culture is the process of culturing single line cells under sterile, controlled conditions, in vitro by exposing them to nutrients, hormones and specific amount of sunlight. There are different steps involved in the tissue culture process.Step 1: Material is selected and sterilized for propagation of cells, in vitro initiating the process of culturing the cells.Step 2: The plant material is re-divided and placed in separate plates with medium rich in plant growth regulators. These growth regulators induce shoot formation. This process can be repeated till the desired number of plants is obtained.Step 3: The hormones which induce the formation of root are introduced into the medium. Now, complete plantlets are formed. These plantlets are transferred from lab into the green house for further growth. | |

Define micelle |
| Answer» A soap molecule consists of two parts – a polar head which is hydrophilic (or water attracting) and a non-polar tail, which is hydrophobic (or water repelling) in nature. When soap molecules are present in water, the molecules arrange themselves in the form of a cluster in such a manner that their non-polar hydrophobic ends are away from the water molecules, and their polar hydrophilic ends are towards the water molecules . This is known as micelle formation and the cluster that is formed is called a micelle. | |
