explain machnisum of exlation |
| 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. | |

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. | |

What is importance of DNA copying in reproduction??( pls answer this question ??...) |
|
Answer» Join betternation.xyz This is a site where u can have a lot of friends and fun ? ? ? DNA copying is an important phenomenon of reproduction through which the organisms pass on their characteristics to their offspring. It maintains the characteristics in different generations of the species. It also produces variations which are useful for the survival of species for long time. DNA contains information for the inheritance of features from parents to next generation. DNA presents in nucleus of cells are the information source for making protein. If information is different, different protein will be made that lead to altered body design. |

State 3 law of mendel |
|
Answer» Law of Dominance:This is also called as Mendel’s first law of inheritance. According to the law of dominance, hybrid offsprings will only inherit the dominant trait in the phenotype. The alleles that are suppressed are called as the recessive traits while the alleles that determine the trait are known as the dormant traits.Law of SegregationThe law of segregation states that during the production of gametes, two copies of each hereditary factor segregate so that offspring acquire one factor from each parent. In other words, allele (alternative form of the gene) pairs segregate during the formation of gamete and re-unite randomly during fertilization. This is also known as Mendel’s third law of inheritance.Law of Independent AssortmentAlso known as Mendel’s second law of inheritance, the law of independent assortment states that a pair of trait segregates independently of another pair during gamete formation. As the individual\xa0heredity\xa0factors assort independently, different traits get equal opportunity to occur together. Any one please answer ?

Give a short paragraph on sexual reproduction in hibiscus plant. |
| Answer» In angiosperms, flower is the reproductive organ of the plant. Stamen, the male reproductive part of flower, is made up of anther and filament. Carpel is the female reproductive part and is composed of stigma, style and ovary.The flower may be unisexual that is, it contains either stamens or carpels or bisexual which contains both stamens and carpels. Stamen produces pollen grains that are yellowish in colour. The ovary contains ovules and each ovule has an egg cell. When a pollen grain falls on the stigma of the carpel, it bursts open and grows into a pollen tube downwards through the style towards the female gamete in the ovary. A male gamete moves down the pollen tube and enters the ovule in the ovary. The tip of the pollen tube bursts open and male gamete comes out of the pollen tube which combines with the nucleus of the female gamete present in the ovule to form a fertilised egg called zygote.\xa0\xa0The pollen needs to be transferred from the stamen to the stigma. The transfer of pollen grains from the anther of a stamen to the stigma of a carpel is called pollination.If this transfer of pollen occurs in the same flower, it is referred to as self-pollination but if the pollen is transferred from one flower to another, it is known as cross-pollination. The process of pollination is achieved by agents like wind, water or animals. After the pollen lands on a suitable stigma, it has to reach the female germ-cells which are in the ovary. For this, a tube grows out of the pollen grain and travels through the style to reach the ovary. The fertilised egg divides several times to form an embryo within the ovule which develops a tough coat around it and is gradually converted into a seed. The ovary of the flower develops and becomes a fruit with seeds inside it. | |

Explain regeneration |
|
Answer» Regeneration is the ability of an organism to grow into a complete individual when its body is divided into any number of pieces. It can be seen in Hydra and Planaria.\xa0Regeneration is carried out by specialized cells which proliferate and further make large number of cells. From this mass of cells, different cells undergo changes to become various cell types and tissues. These changes take place in an organized sequence referred to as development. When the simple animals like Hydra ,Planaria develop a new individual from their broken older part it is known as regeneration. |

How can we write the function of nephron in detail? |
|
Answer» Join betternation.xyz This is a site where u can have a lot of friends and fun ? ? ? Functioning of a Nephron:\tThe blood enters the kidney through the renal artery, which branches into many capillaries associated with glomerulus.\tThe water and solute are transferred to the nephron at Bowman’s capsule.\tIn the proximal tubule, some substances such as amino acids, glucose, and salts are selectively reabsorbed and unwanted molecules are added in the urine.\tThe filtrate then moves down into the loop of Henle, where more water is absorbed.\tFrom here, the filtrate moves upwards into the distal tubule and finally to the collecting duct. Collecting duct collects urine from many nephrons.\tThe urine formed in each kidney enters a long tube called ureter. From ureter, it gets transported to the urinary bladder and then into the urethra. Explain these 3 steps in detail: 1) Filtration 2) selective reabsorption3) tubular secretion |

How are the aveoli designed to maximize the exchange of gases ? |
| Answer» The human respiratory tract is made up of nostril, larynx, nasal chamber, pharynx, trachea, epiglottis,\xa0alveoli, bronchioles, bronchi and lungs.\xa0Within the lungs, the oxygen is exchanged for carbon dioxide waste through millions of microscopic sacs known as alveoli.\xa0The oxygen inhaled diffuses into the capillaries of the lungs, binds to the haemoglobin and is pumped into the bloodstream.\xa0The carbon dioxide from the blood diffuses through the alveoli and is expelled by exhalation.The alveoli are thin-walled and richly supplied with a network of blood vessels to facilitate the exchange of gases between blood and the air-filled in alveoli. They have a balloon-like structure that provides maximum surface area for exchange of gases. | |

Write the concept,merid &dimerid of Döbereiner\'s Triads |
| Answer» Dobereiner\'s law of triads: According to which in certain triads the atomic mass of the central element was merely the arithmetic mean of the atomic masses of the other two elements and the properties of the middle element were in between those of the end members. These families of three elements became known as Dobereiner\'s Triads.Merits- \tFrom this classification, one point became clear that properties of the elements have some relationship with their atomic masses.Demerits-\tIn some triads, all the three elements possessed nearly the same atomic masses, hence the law was rejected.\tThe concept was not applicable to all the known elements but only to a limited number of elements. | |
