what is DNA and explain |
|
Answer» What is DNA?DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix. The somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.An important property of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of the DNA present in the old cell.DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone.DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone.??????????????? DNA or Deoxyribonucleotide is the basis of genetic mechanism. Genes are the specific parts of chromosomes or Deoxyribo Nucleic Acid (DNA) segments which determine the hereditary characteristics.Importance of DNA copying in reproduction:\tDNA copying mechanism is extremely necessary for reproduction as copying of DNA helps in transfer of information or characters from parents to offspring.\tIt also generates variations during sexual reproduction. This variation leads to evolution.\tDNA copying is also necessary because DNA (Deoxyribonucleic acid) is the genetic material found in chromosomes, which are present in the nucleus of a cell.\tDNA determines the body design of an individual. It carries the genetic information and key for the production of every type of cell proteins, which control the function of living organisms.\tDNA copying also helps in proper survival of the organism by similar copying and variation during DNA copying leads to evolution |

Why is the efferent arteriole narrower than the afferent arteriole????? |
|
Answer» Thanks pranali ?? The efferent arteriole carries blood away from the glomerulus. Because it has a smaller diameter than the afferent arteriole, it creates some resistance to blood flow, producing the back-up of blood in the glomerulus which creates higher pressure in the glomerular cavity. |

What is the difference between drift speed and speed of the current |
|
Answer» Hi In physics a\xa0drift\xa0velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field. Applying an electric field adds to this random motion a small net flow in one direction; this is the\xa0drift. The\xa0drift velocity\xa0is directly proportional to\xa0current. The\xa0drift velocity\xa0is the average\xa0velocity\xa0that a particle, such as an electron, attains in a material due to an electric field. In general, an electron will propagate randomly in a conductor at the Fermi\xa0velocity.\xa0The average\xa0velocity\xa0of the free charges is called the\xa0drift velocity\xa0and is\xa0in the\xa0direction opposite to the electric field for electrons. The carriers of the\xa0current\xa0each have charges q and move\xa0with a drift velocity\xa0of magnitude vd.\xa0Current\xa0density is the electric\xa0current\xa0per unit area of cross-section. |

Write the functions of skin, liver and lungs in excretion. |
| Answer» Liver, lungs, and skin also play an important role in the process of excretion.Role of the liver:Liver is the largest gland in vertebrates. It helps in the excretion of cholesterol, steroid hormones, vitamins, drugs, and other waste materials through bile. Urea is formed in the liver by the ornithine cycle. Ammonia – a toxic substance – is quickly changed into urea in the liver and then eliminated from the body. Liver also changes the decomposed haemoglobin pigment into bile pigments called bilirubin and biliverdin.Role of the lungs:Lungs help in the removing waste materials such as carbon dioxide from the body.Role of the skin:Skin has many glands which help in excreting waste products through pores. It has two types of glands – sweat and sebaceous glands.Sweat glands are highly vascular and tubular glands that separate the waste products from the blood and excrete them in the form of sweat. Sweat excretes excess salt and water from the body. | |

How does digestion take place in human body? Explain in detail. |
| Answer» Human Digestive SystemA human digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. The food we take in is digested and utilized by our body and the unused parts of the food are defecated. Human digestive system is the sum of the gastrointestinal tract (GIT; also called alimentary canal) and accessory organs (tongue, liver, pancreas, etc). These two parts together help in digestion in humans.The alimentary canal\xa0is the long tube through which the food that we eat is passed. It begins at the mouth (buccal\xa0or\xa0oral cavity), passes through the\xa0pharynx,\xa0esophagus\xa0or\xa0food pipe,\xa0stomach,\xa0small intestines,\xa0large intestines,\xa0rectum\xa0and finally ends at the\xa0****. The food particles get digested gradually as they travel through various compartments of the alimentary canal. Accessory organs are organs which participate in the digestion process but are not actually a part of GIT. They stimulate the digestion by releasing certain enzymes.Food\xa0begins its journey through the digestive system in the mouth, also known as the buccal cavity or the oral cavity. The mouth has many accessory organs such as the tongue, teeth, and salivary glands, which help in the digestion of food. Teeth grind the food into small pieces. Salivary glands secrete saliva which contains an\xa0enzyme called the salivary amylase. This enzyme breaks down starch content and moistens the food, before the tongue and other muscles push the food into the pharynx.\xa0PharynxThe pharynx passes the chewed food from the mouth to the esophagus. The flap of tissue known as the epiglottis present in pharynx prevents food from entering into the wide pipeEsophagus or Food PipeThe esophagus is a muscular tube connecting the pharynx to the stomach. It carries swallowed masses of chewed food along its length and pushes it down to the stomach.\xa0StomachThe stomach is a thick-walled muscular bag that is located on the left side of the abdominal cavity. It is the largest part of the human digestive system. Stomach acts as a storage tank for food so that the body has time to digest large meals properly. It receives food from the food pipe at one end and opens into the small intestine at the other end. The inner walls of the stomach consist of the gastric glands which secrete mucous, hydrochloric acid and digestive enzymes. These continue the digestion of food that began in the mouth.Mucous protects the lining of the stomach while acid kills bacteria that enter the body along with the food. Hydrochloric acid also makes the medium in the stomach acidic, which helps the digestive enzymes like pepsin to act. The digestive enzymes break down proteins into simpler substances.Small IntestineThe small intestine is the longest part of the human digestive system. It is a highly coiled long, thin tube which is about 7.5 metres in length. The length of the small intestine depends on the diet of the organism. A major proportion of digestion takes place in the small intestines. All types of nutrients are digested here with the help of secretions which it receives from the liver and the pancreas. The walls of the small intestine also secrete juices for digesting food.The liver releases bile juice which alkalizes the acidic food received from the stomach and also emulsifies the fat content. The pancreatic juice digests the proteins and lipids. Finally, the intestinal secretions convert the carbohydrates into glucose, proteins to amino acids and fats into fatty acids and glycerol.Once the food is broken down into the simple particles, it is ready to be absorbed by the body. The villi, finger-like projections present on the walls of the small intestine, absorb the digested food by increasing the surface area. The absorbed food is then transported to different parts of the body through the blood vessels for cell activities.Large IntestineThe large intestine is a long, thick tube which is about 1.5 meters long. The large intestine absorbs water and small amounts of nutrients from the undigested food with the help of many symbiotic bacteria residing in it. The remaining waste passes into the\xa0rectum, where it remains as semi-solid feces. Feces exit the body through the **** via time-to-time excretion. This process is called\xa0Digestion. | |

Why do metals behave as reducing agents????? |
|
Answer» Yes ofcoure i remember u very well☺️☺️☺️ Ishika u remember me U remember me... Hi Generally metals acts as reducing agents. Because metals easily release electrons from their outermost shell to obtain stable octet configuration.For example sodium metal atomic number is 11 its electronic configuration is 2,8,1.To obtain octet configuration or noble gas configuration it easily releases one electron from its outer most shell. Apart from this metals has low ionization potentials ,low energy is required to remove electrons from their valence shell.\xa0 |

Why do we prevent from sleep under tree at night?? |
|
Answer» ??? Kyunki raat mai chudel pakar leti hai Because at night their is no sunlight sothat tree cannot do photosynthsesis.due to this they realsea only carbon dioxide at night ant that lead to difficult in breathing at night as we under the tree. Because in day trees release oxygen and take co2 and in night trees take oxygen and release co2 so it is harmful for all human beings that they didnot get proper o2 under the tree That is, the plants leave carbon dioxide at night. On the basis of this it is that in the night if you sleep under the tree, you will not get oxygen, which can cause breathing problem, suffocation etc. Therefore, Trees are very important for us. They keep the environment pure by helping us in reducing air pollution. |
