Explain briefly the process of respiration in human beings. |
| Answer» Respiration is the process by which energy is released from food in our body. The function of respiratory system is to breathe in oxygen for respiration producing energy from food, and to breathe out carbon dioxide. With the help of lungs gases are exchanged between the blood and the air. Gases exchanged are oxygen and carbon dioxide. We can live without food and water for many days but we cannot live for more than a few minutes without air, as it is necessary for breathing. So, before discussing the human respiratory system, it is necessary to know the process of breathing which is an important part of respiration | |

What is the role of saliva in the digestion of food ??? |
|
Answer» Welcome pranali \xa0Saliva is a fluid which is secreted by the salivary glands. It helps in digestion of food by following Ways.\tSaliva contains a digestive enzyme called salivary amylase, which converts carbohydrates in to maltose sugars.\tIt cleans the mouth cavity and tends to destroy germs that cause teeth decay. It contains lysozomes which help in destroying the bacteria.\tIt moistens and lubricates food which again helps in swallowing.\tIt acts as solvent, dissolving some food particles to stimulate taste buds of the tongue. Thank u ? vaibhav the meaning of guys is used when speaking to a group of men and women The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach |

Define drift speed. |
|
Answer» Thanks both of u When a uniform conductor (resistor) of length L is connected to a battery (voltage V) and is given a potential difference across its ends, there is an electric (electrostatic) field E created through the conductor. Then E = V / L.Due to this potential gradient and field intensity, the charged particles - free electrons (in the conductor) ie., from the conduction band in the atoms - free themselves from atoms and start travelling towards the positive terminal of the battery. Electrons have a charge equal to e. they have a mass = m.The electrons accelerate with acceleration a = e E / m, due to the force = e E on them. Due to collisions of electrons with one another , they lose a lot of momentum and energy (to heat) in each collision. But again they accelerate. They attain a net uniform and steady speed along the length of the conductor from negative terminal towards the positive terminal of the battery. This steady speed is called drift speed.Thus, the movement of particles which move slowly along the medium, under the influence of a field and force is called drift. The speed is called drift speed. I am not Shure Drift Speed: Free electrons moving in a conductor make many collisions with other electrons and atoms. The path of one electron is shown. The average velocity of the free charges is called the drift velocity and is in the direction opposite to the electric field for electrons |

Why does air flow ? |
|
Answer» The movement of air across the earth determines the weather and climate of all regions. The sun’s radiation heats up the land, sea and the air. The land and water bodies also heat up the air, making it less dense. Here, hot air increases and creates a low pressure over that area and cold air sinks and creates a region of high pressure. Air, like all fluids, likes to maintain equal pressure. To do so, cold air from high-pressure areas flows into regions of lower pressure. The primary cause of airflow is the existence of air. Air behaves in a fluid manner, meaning particles naturally flow from areas of higher pressure to those where the pressure is lower. Atmospheric air pressure is directly related to altitude, temperature, and composition. |

Difference between breathing and respiration. |
||
|
Answer» As stated above, breathing is the physical process of exchanging gases between the cells and the environment. The mechanism of breathing involves various respiratory structures such as the windpipe, lungs, and nose. Respiration, on the other hand, is a chemical process that takes place in the cell. | Breathing | Respiration | \tBreathing involves the process of inhaling oxygen and exhaling carbon dioxideRespiration is the process of breaking down of glucose to produce energy which is then used by cells to carry out the cellular function.Breathing takes place in the lungs.Respiration takes place in cells.Breathing is a voluntary physical process.Respiration is an involuntary\xa0chemical process.No energy is produced during the process.Energy is released in the form of ATP.It is an extracellular process, as it occurs outside cells.It is an intracellular process, as it occurs inside cells.No enzymes are used during the process.A large number of enzymes are used during the process.Breathing takes places through respiratory organs like lungs, nose, etc.Respiration takes place in cells and cell organelles like mitochondria, etc.\t|

Explain briefly the process of respiration. |
|
Answer» Nice Answer Respiration is a process in which glucose is broken down with the help of oxygen and energy is released along with the production of carbon dioxide and water.There are two types of respiration i) aerobic respiration ii) anaerobic respiration.Aerobic respiration- the process of respiration that takes place in the presence of oxygen.Example- glucose(a 6-carbon molecule) breaks into pyruvate(a 3-carbon molecule) and in the mitochondria pyruvate is broken down into 3 molecules of carbon dioxide and water with the release of energy.Glucose -->\xa0pyruvate + energy à carbon dioxide + water + energy.Anaerobic respiration- the process of respiration that takes place in the absence of oxygen.Example-\tIn yeast cells, glucose (a 6-carbon molecule) breaks into pyruvate (a 3-carbon molecule) and pyruvate is then converted to ethanol(a 2-carbon molecule) and carbon dioxide.Glucose -->\xa0pyruvate + energy --> ethanol + carbon dioxide + energy.\tIf there is a lack of oxygen in our muscle cells, pyruvate breaks in a different pathway. Glucose (a 6-carbon molecule) breaks into pyruvate (a 3-carbon molecule) and pyruvate is then converted to lactic acid (a 3-carbon molecule) along with the release of energy.Glucose -->pyruvate + energy --> lactic acid + energy. |

Which process is responsible for opening and closing of stomata??? |
|
Answer» Hi Transpiration I think transpiration Stomata are small pores or opening present in the epidermal cells of leaves. They open during the day and close during night. They take carbon dioxide required during photosynthesis during the day. Also, they release excess water released in the process of respiration during the night along with carbon dioxide. This opening and closing of stomata is controlled by concentration of solutes in the guard cell.During daytime, the pH of the guard cells is alkaline. This results in the hydrolysis of water. The solutes from neighbouring epidermal and mesophyll cells enter the guard cells and lowers the osmotic potential and water potential of guard cells. This lowered water potential and osmotic potential allow the movement of water into guard cells from neighbouring cells. Due to this, guard cells become turgid. This results in the opening of the guard cells. During night time, carbon dioxide accumulates in the guard cells. Hence, it becomes acidic. The acidic pH favors the formation of starch in the guard cells.\xa0Hence, the solute concentration decreases. This makes the water from the guard cells to move away into neighbouring cells. The guard cells then become flaccid with no water. They collapse against each other and result in the closing of stomata.\xa0 |

Suggest some consequences due to the loss of biodiversity???? |
| Answer» \tLoss of biodiversity can result in loss of balance in the ecosystem due to depletion of natural resources and increase in deforestation.\tThis had led to imbalance in food chains, loss of natural habitats of animals and birds, increase of pollution, wide change in climate etc.\tAn unstable ecosystem will be more likely to lose species. Several species like the Dodo bird, Cheetah, pink headed duck, etc. have already become extinct and there are several species like Bengal tiger, one horned rhinoceros that are already on the verge of extinction.\tLosing species means losing potential\xa0foods,\xa0medicines, industrial products, and\xa0tourism, all of which have a direct economic effect on the life of people.\tTherefore, loss of biodiversity can lead to a loss of ecological stability. | |

Is any reason behind activation of volcano??? |
|
Answer» Hii sanket i want to ask u one thing When a part of the earth\'s upper mantle or lower crust melts, magma forms. A volcano is essentially an opening or a vent through which this magma and the dissolved gases it contains are discharged. Although there are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber. |
