Why living organism classified |
|
Answer» To make study easier of understanding the organism Living organism classfied to make study easier of whole organism 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. |

How is key helpful in the identification and classification of an organism |
| Answer» Key\xa0is a taxonomical aid that\xa0helps\xa0in\xa0identification\xa0of plant and animal\xa0species. These\xa0keys\xa0are based on similarities and dissimilarities in characters, generally in a pair called couplet. Each statement in a taxonomic\xa0key\xa0is referred to as a lead. It is also\xa0useful\xa0in\xa0identification\xa0of unknown\xa0organisms.\xa0All\xa0living\xa0things are organized into groups by scientists as they are identified. Different scientists use various systems of\xa0classification\xa0to organize all\xa0living\xa0things into groups. Overall, the reason scientists\xa0classify living\xa0things is to understand the relationships between different\xa0organisms.\xa0Key\xa0is a device used by biologists for identifying unknown organisms.\xa0Keys\xa0are constructed so that the user is presented with a series of choices about the characteristics of the unknown organisms; by making the correct choice at each step of the\xa0key, the user is ultimately led to the identity of a specimen. | |

Explain the exchange of gases between the alveoli and blood capillaries |
| Answer» In human beings, air is taken into the body through the nostrils, is filtered by fine hairs that line the passage. When air passes through the nasal passage, the dust particles and other impurities present in it are trapped by nasal hair and mucus so that clean air goes into the lungs. From here, the air passes through the throat and into the lungs. Trachea does not collapse even when there is no air in it because it is supported by rings of soft bones called cartilage.Within the lungs, the passage divides into smaller and smaller tubes which finally terminate in balloon-like structures which are called alveoli. The alveoli provide a surface where the exchange of gases can take place. The walls of the alveoli contain an extensive network of blood-vessels. When we breathe in, the ribs are lift up and the diaphragm flattens which increases the size of the chest cavity. Because of this, air is sucked into the lungs and fills the expanded alveoli. The blood brings carbon dioxide from the rest of the body for release into the alveoli, and the oxygen in the alveolar air is taken up by blood in the alveolar blood vessels to be transported to all the cells in the body. During the breathing cycle, when air is taken in and let out, the lungs always contain a residual volume of air so that there is sufficient time for oxygen to be absorbed and for the carbon dioxide to be released.\xa0 | |

Megaspor |
| Answer» Microspores\xa0are male spores.\xa0Megaspores\xa0are females pores.\xa0Microspore\xa0is the first cell of male gametophytic generation.\xa0Megaspore\xa0is the first cell of female gametophytic generation.\xa0A\xa0megaspore\xa0mother cell, or megasporocyte, is a\xa0diploid\xa0cell in plants in which meiosis will occur, resulting in the production of four\xa0haploid megaspores. At least one of the spores develop into\xa0haploid\xa0female gametophytes (megagametophytes). The\xa0megaspore\xa0mother cell arises within the megasporangium tissue. | |
