What is the nuclear energy |
| Answer» Nuclear energy is energy in the nucleus (core) of an atom. Atoms are tiny particles that make up every object in the universe. There is enormous energy in the bonds that hold atoms together. Nuclear energy can be used to make electricity. But first the energy must be released. It can be released from atoms in two ways: nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. This is how the sun produces energy. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. Nuclear power plants use nuclear fission to produce electricity. | |

Differentiate between aerobic and anaerobic respiration which do you think better for organisms |
| Answer» Aerobic1.Aerobic respiration takes place in the presence of oxygen.2. Complete break down of food occurs in it.3. The end product are carbon dioxide and water.4. It produces a considerable of energy , due to complete oxidation of food moleculesAnaerobic1. Takes place in the absence of oxygen2. The end product may be ethyl alcohol and CO2 or lactic acid3. Much less energy is produced, due to incomplete oxidation of food. | |

Explain how the pesticides enter a food chain and subsequently get into our body |
| Answer» A large number of pesticides and chemicals are used to protect our crops from pests and diseases. Some of these chemicals are washed down from the soil, while some enter the water bodies. From the soil, they are absorbed by plants along with water and minerals, and from the water bodies, they are taken up by aquatic plants and animals. This is how these chemicals enter the food chain.As these chemicals cannot decompose, they accumulate progressively at each trophic level with increased concentration at each tropic level, by process well-known as bio magnification. We human beings occupy the top most level in any food chain, these chemicals get accumulated in our bodies in maximum amount. | |

What are the different parts of the human eye and their function |
|
Answer» \tPupil- The inner aperture that we can see in the centre of the eye is known as pupil. It is like a hole through which light enters the eye.\tIris- It is coloured part of the eye and is involved mainly in controlling the size of pupil. The iris increase and decrease the size of pupil and regulate the amount of light that enters through the pupil.\tSclera- The white part of the eye that we can see is known as sclera. It is filled with a clear watery fluid.\tCornea- It is a thin transparent tissue that covers the front of the eye.\tRetina- Just behind the eyeball, there is a lining called the retina. It is retina that is sensitive to light and has receptors called rods and cones. The rods and cones respond to light and generate impulses.\tRods are the cells which are sensitive to dim light.\tCones are the cells which are sensitive to bright light.\tCiliary Muscles- They controls the focal length of the eye lens.\tLens- It is the transparent tissue between pupil and retina. The lens helps in focusing the light that passes through the pupil into eye. This helps in focusing the image on the retina, by bending the light rays.\tOptic Nerve- It connects the eye to brain and carries impulse to and from the brain.\tBlind Spot- The portion on retina where the nerves fibres enters the optic nerve. This portion does not have any rods and cones. The image falling on this portion of retina cannot be seen. This spot is known as Blind Spot. Wow that\'s amazing way to answer |

Explain the flow of blood from heart systematically mentioning and deastole |
|
Answer» First the oxygenated blood from the lungs comes to the heart in the left atrium through the pulmonary vein.Then the blood gies to the left ventricle and then the heart pumps and blood gets out of the heart through the Arota.The blood is then carried by the arteries all over the body to the tips of the fingers.It gives the oxygenated blood to the organs and collects the deoxygenated blood from there.When it is full of deoxygenated blood then it is known as the vein.Tue vein carries the deoxygenated blood from the body to the heart in the right atrium through the vena cava.Then the blood is passed in the right ventricle then the heart pumps and the blood gets out of the body from the pulmonary artery to the lungs. Blood enter the heart through two large veins- the posterior and anterior vena cava- carrying deoxygenated blood from the body into right Atrium. Blood flow from right Atrium to right ventricle through the triscupid valve |

Short note on human heart |
| Answer» Human heart has four chambers these are right artrium, left artrium, left ventricle and right ventricle. The right and left side of the heart is divided by a separation known as septum. Heart is a pumping organ that circulates blood in human body two times in one complete cycle. The deoxygenated blood is brought to heart by veins and the oxygenated blood is transported to other parts of the body by arteries. | |

What is a c generator |
| Answer» In electricity generation, a generator[1] is a device that converts motive power (mechanical energy) into electrical power for use in an external circuit.

Differentiate between redox and double displacement reaction |
|
Answer» Double displacement reactions involve the exchange of ions of the reacting substances but not loss or gain of electrons. On the other hand, any reaction involving loss or gain of electrons is a redox reaction. At least 4 points are necessary to define it In double displacment reacn. Tow most reactive element displace 2 least reactive element . While in redox reacn. O2 or H2O are gain or loss |
