Define the following in one word Body-building nutrients which are needed for the repairingand building of body tissues, |
|
Answer» Answer: (a) CARBOHYDRATES are ONE of the main types of nutrients found in food. They are the most important source of energy for the body of many organisms, including humans. Carbohydrate provides about 4 kcal per gram and is the energy that is used first to fuel muscles and the brain. Fat is also one of the three main macronutrients, along with carbohydrate and PROTEIN. COMPARED to carbohydrate and protein, each gram of fat provides more than twice the amount of calories (9 kcal per gram). So, the answer is Carbohydates and Fats. (b) Protein is the major structural component of cells and is responsible for the building and repair of body tissues. Proteins are organic molecules made up of amino acids – the building blocks of life. These amino acids are joined together by chemical bonds. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs. So, the answer is Proteins. (c) Vitamin A is a fat soluble vitamin that is also a powerful antioxidant. Vitamin A plays a CRITICAL role in maintaining healthy vision, neurological function, healthy skin, healthy immune system, and cell growth. So, the answer is Vitamin A. (d) Minerals are components of foods that are involved in many body functions. For example, calcium helps to maintain and build strong bones and teeth and iron is needed for our red blood cells to transport oxygen. So, the answer is Calcium. |

Differentiate between thermosets and thermoplastics |
|
Answer» Answer: The primary physical difference is that thermoplastics can be remelted back into a liquid, whereas THERMOSET plastics always remain in a permanent SOLID state. Think of thermoplastics as butter – butter can be MELTED and cooled MULTIPLE times to form various shapes. hope it will help you mark as brainlist answer plz |

Explain why the value of g is zero at the center of earth |
|
Answer» ➥As the DISTANCE from the centre DECREASES, the acceleration DUE to GRAVITY also decreases. At the centre the distance is zero, hence gravity is zero. The value of 'g' is 9.8.'g' is acceleration due to gravity.At the centre of the earth it will turn zero because there will be no acceleration at the centre of the earth. |

Two circularly polarized waves traveling normally out of the page have electric fields given by Eleft = 3 et of and Eright = 4 ei t volt / meter. For the resultant wave, find the sense of rotation, axial ratio, y, ɛ, T, 6, and the average power per unit area conveyed by the resultant wave. |
|
Answer» Answer: The electric field vectors of a traveling circularly polarized electromagnetic wave. This wave is right-circularly-polarized, since the direction of rotation of the vector is related by the right-hand rule to the direction the wave is moving; or left-circularly-polarized according to alternative convention. In electrodynamics, CIRCULAR polarization of an electromagnetic wave is a polarization state in which, at each point, the electromagnetic field of the wave has a constant MAGNITUDE but its direction rotates at a constant rate in a plane perpendicular to the direction of the wave. In electrodynamics the strength and direction of an electric field is defined by its electric field vector. In the case of a circularly polarized wave, as seen in the accompanying animation, the tip of the electric field vector, at a given point in space, describes a circle as time progresses. At any INSTANT of time, the electric field vector of the wave indicates a point on a helix oriented along the direction of propagation. A circularly polarized wave can rotate in one of two possible senses: right circular polarization in which the electric field vector rotates in a right-hand sense with respect to the direction of propagation, and left circular polarization in which the vector rotates in a left-hand sense. Circular polarization is a LIMITING case of the more GENERAL condition of elliptical polarization. The other special case is the easier-to-understand linear polarization. The phenomenon of polarization arises as a consequence of the fact that light behaves as a two-dimensional transverse wave. |

Pls answer for this question |

Answer» Answer: C. Sublimation: It is the process of changing the solid state into the gaseous state on heating and vice-versa on cooling. Turning the gaseous state back into the solid state is known as Deposition. Eg. Napthalene balls, camphor, etc. d. Boiling Point: It is the fixed temperature at which a liquid starts to BOIL. The boiling point of water is 100⁰ C. e. Freezing Point: It is the fixed temperature at which a liquid state changes into its solid state on cooling. The freezing point for H2O is 0⁰ C. Q3. EVAPORATION: It is the process of changing a liquid state into its vapors state on heating. Evaporation takes place at all temperatures. Alcohol evaporates at 78⁰C. The factors affecting the rate of evaporation are: 1. Humidity around the liquid. 2. The air blown on the surface of the liquid. 3. Volatile the liquid. 4. Larger the surface area. Q4. Evaporation is an endothermic reaction, henceforth it requires heat. It takes away the heat from its surroundings and produce a sensation of cooling. Eg. We feel cool, when air blows over our BODY sweat. I KNEW just these many questions only. Hope they helped you. Thank you. |

How is roughage important to us |
|
Answer» Answer: Roughage does not provide any nutrient to our body, but is an essential component of our food and adds to its bulk. This helps our body GET rid of undigested food. ... Water helps our body to absorb nutrients from food. It also helps in throwing out some wastes from body as urine and sweat. Explanation: Roughage, or fiber, has long been recommended to HELP with digestive issues like constipation, but it also plays many other IMPORTANT roles in your body. For example, the roughage in plant foods can promote optimal gut health, help you manage your weight, and even reduce your risk of heart disease. In those guidelines, issued in 2005, the USDA recommends getting 14 grams of dietary fiber for every 1,000 calories you consume. So if you consume 2,000 calories per day, you should get 28 grams of dietary fiber that day. Fiber is found naturally in FRUITS, vegetables, whole grains, and legumes.

Difference between mitosis and meiosis |
|
Answer» Answer: The difference between mitosis and meiosis are as follows: Mitosis was discovered by Walther Flamming, while meiosis was discovered by Oscar Hertwig. Karyokinesis occurs in mitosis during INTERPHASE while it occurs in meiosis during interphase 1 Cytokinesis occurs only in telophase during mitosis while it occurs in Telophase 1 and telophase 2 during meiosis.
