What is nuron |
| Answer» A neuron is a microscopic structure composed of three major parts, namely, cell body, dendrites and axon.Cell Body: The cell body contains cytoplasm with typical cell organelles and certain granular bodies called Nissl’s granules.Dendrites: Short fibres which branch repeatedly and project out of the cell body also contain Nissl’s granules and are called dendrites. These fibres transmit impulses towards the cell body.Axon: The axon is a long fibre, the distal end of which is branched. Each branch terminates as a bulb-like structure called synaptic knob which possess synaptic vesicles containing chemicals called neurotransmitters. The axons transmit nerve impulses away from the cell body to a synapse or to a neuro-muscular junction. | |

Why are living organisems classified? |
|
Answer» Living organisms classified for making study easier of each and every individuals out of millions of plant and animals A large variety of plants, animals, and microbes found on earth and they differ in size, shape, colour, habitat, and many other characteristics. So, studying each of them is impossible. Therefore, scientists have devised mechanisms to classify all living organisms on certain rules and principles that allow identification, nomenclature, and finally classification of an organism.For example, based on presence of three pairs of legs and 2 pairs of wings, an organism is identified as an insect, it will be given a scientific name and then grouped with other similar organisms. Thus, various groups or taxon include organisms based on their similarity and differences.Therefore, the biological classification helps in revealing the relationship between various organisms. It also helps in making study of organisms easy and organized. Yes |

Short note on complementary nature of DNA |
| Answer» Nucleic acid\xa0sequence\xa0of bases that can form a double- stranded structure by matching base pairs. For example, the\xa0complementary sequence\xa0to C-A-T-G (where each letter stands for one of the bases in\xa0DNA) is G-T-A-C.\xa0Complementary DNA\xa0(cDNA) is the\xa0DNA\xa0produced on an RNA template by the action of reverse transcriptase (RNA-dependent\xa0DNA-polymerase). The sequence of the cDNA becomes\xa0complementary\xa0to the RNA sequence.\xa0In\xa0nature complementarity\xa0is the base principle of\xa0DNA\xa0replication and transcription as it is a property shared between two\xa0DNA\xa0or RNA sequences, such that when they are aligned antiparallel to each other, the nucleotide bases at each position in the sequences will be\xa0complementary. | |

What is difference between growth and reproduction? |
|
Answer» Growth has to do with organisms adapting to new changes in their physiology, such as a child growing into an adult. Reproduction, however, is when a new organism is formed from another in the same species or family. Growth occurs throughout the lifespan but not uniformly. It occurs at a faster rate until a plant or animal attains maturity. After this stage, gradually growth slows down and stops after a particular time.This entire process and phenomena, where an organism, grows physically, evolves physiologically, attains mental growth and maturity. This is collectively known as Development.\xa0The process of development of shape and structure of a living organism is known as Morphogenesis, whereas Differentiation is the process of change in cells, tissues and internal & external organs. |

Difference between the polysaccharide and chitin |
|
Answer» Chitin is a large, structural polysaccharide made from chains of modified glucose. Chitin is found in the exoskeletons of insects, the cell walls of fungi, and certain hard structures in invertebrates and fish. In terms of abundance, chitin is second to only cellulose. In the biosphere, over 1 billion tons of chitin are synthesized each year by organisms. This extremely versatile molecule can form solid structures on its own as in insect wings, or can combine with other components like calcium carbonate to make even stronger substances like the shell of a clam. I don\'t know |
