The focal length,f=r/2 |
| Answer» The focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system\'s optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light. A system with a shorter focal length bends the rays more sharply, bringing them to a focus in a shorter distance or diverging them more quickly. For the special case of a thin lens in air, a positive focal length is a distance over which initially collimated (parallel) rays are brought to a focus, or alternatively a negative focal length indicates how far in front of the lens a point source must be located to form a collimated beam.\tFor spherical mirrors of small apertures, the radius of curvature is found to be equal to twice the focal length.\tThe focal length (f) of a mirror is the distance between its pole (P) and principal focus (F).\t\tFor spherical mirrors of small aperture, R = 2f.\t | |

Explain the digestive system??? |
| 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.\xa0Pharynx:\xa0The 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 Pipe:\xa0The 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.\xa0Stomach:\xa0The 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 Intestine: The 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 Intestine:The 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. | |

Define grafting ❤️? (good evening everyone)। ??❤️???? |
|
Answer» Hi everyone ?❤️??? Hii Hello Grafting:Grafting\xa0is a\xa0horticultural technique used to join parts from two or more plants so that they appear to grow as a single plant. In grafting, the upper part (scion) of one plant grows on the root system (rootstock) of another plant.In grafting, one plant is selected for its roots, and this is called the stock or rootstock. The other plant is selected for its stems, leaves, flowers, or fruits and is called the scion. The scion contains the desired genes to be duplicated in future production by the stock/scion plant. For successful grafting to take place, the vascular cambium tissues of the stock and scion plants must be placed in contact with each other. Both tissues must be kept alive until the graft has taken, usually a period of a few weeks. Successful grafting requires that a vascular connection takes place between the two tissues. Grafting is most commonly used for the propagation of trees and shrubs grown commercially. Grafting is limited to dicots and gymnosperms. |

Explain the three pathways of breakdown of glucose in living organisms |
|
Answer» Thnku prabal ? Thnku yogita ? In the process of respiration, the first step is the breakdown of glucose, a 6-carbonmolecule breaks into 2 molecules of 3-carbon molecule called pyruvate. This process takes place in the cytoplasm. The subsequent breakdown pathway depends on the absence or presence of oxygen as follows(i) Aerobic respiration it takes place in the mitochondria in the presence of oxygen. Pyruvic acid is converted into carbon dioxide, and water thus releasing a lot of energy.(ii) Anaerobic respiration It takes place in the cytoplasm in the absence of oxygen. Pyruvic acid is converted either into CO2 and ethanol (in case of microbes, i.e., fermentation in yeast) or into lactic acid (in the case of muscle cells during sudden activity in humans.) Aerobic respirationAlcoholic fermentationLactic acid formation |
