How exchange of gases take place in plants? |
|
Answer» Exchange of gases take place in plants through stomata pores exchange of gases takes place in stomata there are two guard cell like structure which sea and see the entry of the gases because if anyany foreigner foreign material would enter the cell he will destroy the whole cell and the lysosome will get blast so that\'s why there are guard cells which allow only some gases to get in like oxygen and water because they need plants need carbon dioxide as well as oxygen to make food that\'s why there are stomata which see that other material would not enter the cell. plants take carbon dioxide during daytime to perform their photosynthesis process. the Oxygen gas which is released during photosynthesis process is used by plants in small amount for this respiration. And during night time plants take Oxygen gas for their respiration and release carbon dioxide form during during the daytime after this process plants oxygen plants release oxygen and we smell that oxygen so that we can survive because we need to survive on this earth if we will not survive there would be no future if there will be no future we will have to live in this normal land so that\'s why this process is important Exchange of gases take place in plants through stomata pores. Plants take carbon dioxide gas during day time to perform their photosynthesis process .The oxygen gas which is released during photosynthesis process is used by plants in a small amount for their respiration . And during night time plants take oxygen gas for their respiration and release carbon dioxide form during the process of photosynthesis. Through stomata |

Write the name of basic carbonate layer which formed on copper vessels. |
| Answer» Copper\xa0turns\xa0green\xa0because of chemical reactions with the elements. Just as iron that is left unprotected in open air will corrode and form a flaky orange-red outer\xa0layer,\xa0copper\xa0that is exposed to the elements undergoes a series of chemical reactions that give the shiny metal a pale\xa0green\xa0outer\xa0layer called\xa0a patina.\xa0Copper\xa0metal when exposed to air turns\xa0green\xa0in colour due to corrosion. When\xa0copper\xa0vessel is exposed to air in rainy season, the metal reacts with gases and moisture and atmospheric gases to form a mixture of\xa0copper\xa0carbonate and\xa0copper\xa0hydroxide. This\xa0gives\xa0a\xa0green\xa0colour to the surface of\xa0copper\xa0metal. | |

Draw the labelled diagram of the human respiratory system |
|
Answer» Google karle Exchange of gases takes place between the alveoli of lungs and the surrounding blood capillaries. The two main gases exchanged are oxygen and carbon-dioxide. Oxygen is absorbed by the blood capillaries from the lungs alveoli by diffusion while carbon dioxide is absorbed by the lungs alveoli from blood capillaries by diffusion.\xa0Transport of oxygen and\xa0carbon dioxide occurs with the help of respiratory pigment called hemoglobin.\xa0Haemoglobin, the iron-containing respiratory pigment is a red coloured pigment of blood, which has a very high affinity for oxygen. Haemoglobin though is purple coloured but oxyhemoglobin is of bright red colour. Oxygen is transported from lungs to the body cells in the form of oxyhemoglobin.\xa0Carbon dioxide is transported from the body cell to the lungs in the forms of carboxyhemoglobin, carbonic acid, bicarbonates of sodium and potassium. |

How do variation ensure the survival of a species? The explain with an example |
| Answer» Variations arise in organism by:The phenomenon is the passing of genes and heredity.Variation occurs when one gene in the organism is mutated.If it allows the organism to survive longer than the others in the population without the mutation, it gives the mutated organism a higher chance to pass on its genes. When these genes are passed on, their kids may have the mutation but they will carry the mutated gene. As long as this helps the organism survive it will continue to be passed on to the next generation. After many generations, the mutated trait becomes common which means they have evolved.Example- For example, a population of long beaks inhabit a particular area. Now, the food can be consumed properly with short beaks. If due to some variations, there may be a possibility that there are some birds with short beaks in that population. So, in the new area, they will survive better and reproduce more which will lead to the evolution of more and new species.II.\xa0Variations is useful for the survival of species because:1. Variation acts as a source of raw material for evolution of species.2. Variation leads to genetic diversity, which is a key for the evolution of species. Animals are able to adapt themselves to the changing environment by inheriting some of the beneficial variations. Organisms are better suited to face the struggle for existence due to the presence of variations.3. Variations give the species an individuality of their own. In the absence of variation, there would be no science of heredity as all individuals of a race, would be identical to one another in all aspects.All the variants, however, do not have equal chances of survival. Depending on the environmental conditions, the nature favours only those variants that are able to adjust to the changing environment. The theory of natural selection favours the survival of the fittest.\xa0 | |

What are the 5 major disadvantages of building dams? |
|
Answer» The disadvantages of building large dams are:\tDamming of rivers and regulating their flow result in excessive sedimentation at the bottom of the reservoir. This may hamper aquatic life and their migration to other water bodies.\tBuilding of dams result in the submergence of land and vegetation. This results in the decomposition of vegetation.\tConstruction of large dams results in the displacement of villagers and communities. The villagers have to give up their lands and their means of livelihood.\tLarge forest areas are also submerged because of the building of dams. This threatens our biodiversity.\tDams which were initially built to control floods are now causing floods because of sedimentation. In case of excessive rainfall, the release of water from dams often floods the area, causing damage to lives and property. The major 5 disadvantages of building dams are-:1.It causes soil erosion2.It causes deforestation3.It deflects the way of flowing rivers |

What is amoeba and write its function also |
|
Answer» According to your question, amoeba is a unicellular organism and it functions as a very important member or food chain as a scavenger but in context of mode of nutrition you can define it as holozoic as you have another answer so you can relate. The mode of nutrition in Amoeba is holozoic and various steps involved in the process of nutrition are:Ingestion: Amoeba ingests food with the help of its finger-like extensions, called pseudopodia, when a food particle approaches Amoeba it forms pseudopodia around it and forms a food vacuole inside the AmoebaDigestion: Various enzymes from the cytoplasm enter into the food vacuole and break them down into simple soluble moleculesAbsorption: The simple soluble food is absorbed by cytoplasm of Amoeba from food vacuoles through the process of diffusionAssimilation: Amoeba cell obtains energy from the absorbed food through respiration and this energy is utilized by Amoeba for its growth and repair of the bodyEgestion: When a considerable amount of undigested food gets collected inside Amoeba, its cell membrane ruptures and throws out the undigested food |

Explain the process of fat digestion in the gut of man? |
| Answer» The process of digestion of fats begins in the stomach. The glands of stomach secrete a small amount of gastric lipase that breaks down the fats present in the food. From the stomach the partially digested food goes into small intestine where the pancreatic lipase breaks down the emulsified fats. The walls of small intestine secrete intestinal juice which converts the fats into fatty acids and glycerol. | |

How are Our lungs designed to absorb maximum amount of gases |
| Answer» Within the lungs, the air passage divides into smaller and smaller tubes which finally terminate in balloon like structures called alveoli. The alveoli provide a surface where the exchange of gases can take place. The 2 lungs together have about 300-500 million alveoli. The walls of the alveoli are supplied with an extensive network of blood vessels. So lungs maximise the area for gaseous exchange through the presence of large number of alveoli which are richly supplied with blood. | |
