Draw a ray digram to show that formation object is front of concave mirror |
| Answer» You try to draw the ray diagram of concave mirror as i cannot draw here .. Just i may guide how to draw it.• Draw a line which we refer as a principle axis.• Now mark a point on principle axis as C (center of curvature) & now take certain radius of concave mirror & draw an arc from point C.• The arc drawn is a concave mirror (if the inner spherical surface of mirror is reflecting side then it will be concave mirror , it means outer surface shade it as it is non reflecting surface.) • The arc where it joined the line ( principle axis) that point is referred as pole (P) . Remember that in mirror ray diagrams every meauserment will be meausered from pole only.• Now draw the erect arrow mark as an object on principle axis at certain distance from pole (P) that will be the object distance, which we denote as u . • Now u draw a line parallel to the principle axis from object head to the concave mirror which acts as incident ray towards mirror.•In concave mirror if incident ray is parallel to the principle axis then the reflected ray will emerges(reflects & passes) from principle focus (F).. Till this step u try last step i wil inform u on call & my contact number is 9480266870 | |

Whar are platlets???? |
|
Answer» \tPlatelets are the colorless tiny blood cells without nucleus, circulate through the blood stream.\tDuring injury, the bleeding needs to minimize naturally.\tLeakage of blood can also reduce the efficiency of the pumping system due to the loss of pressure.\tPlatelet cells are present in the body to plug the leaks and to stop bleeding by clotting the blood at the points of injury.\tPlatelets circulate around the body and clot the blood whenever wherever necessary. PLATLET are the blood vessals which helps to cloting the woond Paltelets are the blood vessels which helps in clotting of blood.. |

Compare and contrast fossil fuels and the sun as direct source of energy |
| Answer» Sun is the direct source of energy, while fossil fuels are formed because of the solar energy stored in them. When green plants prepare food, they convert the solar energy into chemical energy which is stored in the form of biomass. The same biomass gets transferred to the animals. Thus, the energy in the form of biomass which is stored in fossil fuels has come from the sun. | |

define sympathetic nervous system and parasympathetic narvous system |
| Answer» \tSympatheticParasympathetic The main function of the sympathetic nervous system is to ready the body’s “fight or flight” responseMain function of the parasympathetic nervous system is to maintain homeostasis and also, enable the “rest and digest” responseSympathetic system prepares the body for any potential dangerParasympathetic system aims to bring the body to a state of calmSympathetic system has shorter neuron pathways, hence a faster response timeHas comparatively longer neuron pathways, hence a slower response timeIncreases heart beat, muscles tense upReduces heart beat, muscles relaxThe pupils dilate to let in more lightThe pupils contractSaliva secretion is inhibitedSaliva secretion increases, digestion increasesOn “fight and flight” situations, Adrenaline is released by the adrenal glands, more glycogen is converted to glucoseNo such function in “fight or flight” situations\t | |

List two components of an ecosystem |
| Answer» There are two main components of the ecosystem, namely: – biotic and abiotic components.\tAbiotic ComponentsThey are the nonliving component of an ecosystem. It includes air, water, soil, minerals, sunlight, temperature, nutrients, etc.\tBiotic ComponentsThey are the living components of an ecosystem. It includes biotic factors such as producers, consumers, and decomposers.\tProducers include all autotrophs (plants), they produce their own food by utilizing the source of energy obtained from the sunlight. All living beings are dependent on plants for both oxygen and food.\tConsumers include primary consumers and secondary consumers. Top carnivores and apex predators make up the tertiary consumers.\tDecomposers include saprophytes (fungi and bacteria), that converts the dead matter into nitrogen and carbon dioxide. They are essential for recycling of nutrients to be used again by the producers. | |

What is ocean thermal energy ? How is it uses to produce energy |
| Answer» The ocean thermal energy is the heat energy generated from the difference in temperature of the ocean water layer at the different depth.\tThe surface of the ocean is at a higher temperature than the layers below. This is because of the sun\'s heat warms up the upper layers of the sea.\tThis temperature difference is exploited to generate energy\tA minimum temperature difference of 20 degrees C is needed between water at the surface and at a depth of about 2 km.\tThis requires Ocean Thermal Energy Conversion plants which converts ocean thermal energy to electricity. | |

Write short note on indicator maximum 2 page |
| Answer» Substances which show the acidic or basic behavior of other substance by change in colour are known as indicator.Type of Indicator: There are many types of indicators. Some common types of indicators are\tNatural\tOlfactory Indicator\tSynthetic Indicator\tUniversal IndicatorNatural Indicator: Indicators obtained from natural sources are called natural indicators. Litmus, turmeric, red cabbage, China rose, etc. are some common natural indicators used widely to show the acidic or basic character of substances.Litmus: Litmus is obtained from lichens. The solution of litmus is purple in colour. Litmus paper comes in two colour – blue and red.\tAn acid turns blue litmus paper red.\tA base turns red litmus paper blue.Turmeric: Turmeric is another natural indicator. Turmeric is yellow in colour. Turmeric solution or paper turns reddish brown with base. Turmeric does not change colour with acid.Red cabbage: The juice of red cabbage is originally purple in colour. Juice of red cabbage turns reddish with acid and turns greenish with base.Olfactory Indicators: Substances which change their smell when mixed with acid or base are known as olfactory indicators. For example onion, vanilla, clove, etc.Onion: Paste or juice of onion loses its smell when added with base. It does not change its smell with acid.Vanilla: The smell of vanilla vanishes with base, but it’s smell does not vanishes with an acid.Olfactory indicators are used to ensure the participation of visually impaired students in laboratory.Synthetic Indicator: Indicators that are synthesized in laboratory are known as synthetic indicators. For example; phenolphthalein, methyl orange, etc.Phenolphthalein is a colourless liquid. It remains colourless with acid but turns into pink with a base.Methyl orange is originally orange in colour. It turns into red with acid and turns into yellow with base.Universal Indicator:Using a litmus paper, phelophthalein, methyl orange, etc. only the acidic or basic character of a solution can be determined, but use of these indicators does not give the idea about the strength of acid or base. So, to get the strength as well as acidic and basic nature of a given solution universal indicator is used.Universal indicator shows different colour over the range of pH value from 1 to 14 for a given solution. Universal indicator is available both in the form of strips and solution. Universal indicator is the combination of many indicators, such as water, propanol, phelophthalein, sodium salt, sodium hydroxide, methyl red, bromothymol blue monosodium salt, and thymol blue monosodium salt. The colour matching chart is supplied with universal indicator which shows the different colours for different values of pH. | |

Why is blood circulation in human heart called double circulation |
|
Answer» As the blood passes through heart twice so it is called double circulation The blood circulation in human heart is called double circulation because the blood passes through the heart twice in one complete cycle of the body – once through the right half in the form of deoxygenated blood and once through the left half in the form of oxygenated blood. |
