What is emulisification of fat? |
|
Answer» lol ??? ☺️??????? Not a problem ✌? Thnx Priya,?? Emulsification of fat is the breakdown of large fat globules into smaller, uniformly distributed particles. It is accomplished mainly by bile salts in the small intestine. ... Emulsification greatly reduces the interfacial tension of fat and allows that fat to be broken into small particles for easier digesting by enzymes. |

What is reflex action? Explain with the help of an example. |
|
Answer» Not a problem dear? In a reflex action, the spinal cord along with the brain stem is responsible for the reflex movements. A few examples of reflex action are: When light acts as a stimulus, the pupil of the eye changes in size. Sudden jerky withdrawal of hand or leg when pricked by a pin.

Can we use galvanometer as a voltmeter ? Give reason for your answer. |
| Answer» Voltmeter is an electrical measuring device, which is used to measure potential difference between two points in a circuit. Voltmeter is always connected in parallel to a circuit.Since Galvanometer is a very sensitive instrument, therefore it can not measure high potential difference. In order to convert a Galvanometer into voltmeter,\xa0a very high resistance known as "series resistance" is connected in series with the galvanometer. | |

What is the work of brushes in electric motors |
| Answer» The brushes transfer the electricity from outside the motor to the spinning winding in the center of the motor. They undergo quite a lot of friction, and after a while wear out. Carbon is used as it is a reasonable conductor, and is soft enough to wear down instead of wearing down the "comutator" - the ring the brushes press against. Brushes are designed to be replaceable in large motors because of this.When brushes are first put into a motor they won\'t be the exact same shape and size as the commutator (which may have had a small amount of wear) and thus won\'t make a perfect smooth contact. With time the brushes will wear to fit the commutator perfectly. The noise you hear is probably the brushes undergoing this initial shaping wear and will stop soon enough.Also, the brushes are located inside a tube-like recess, and are pushed against the commutator using small springs. If the noise doesn\'t stop after a while a small amount of grease to help stop vibration in the brushes may be in order. make sure of the thermal properties of the grease though, as brushes are liable to get rather hot. | |

Explain why adrenaline hormone is called the hormone of ‘fight’ or ‘flight’. |
|
Answer» Thanks for your answer? ✌ The inner glands produce adrenaline. Adrenaline is also known as the “fight-or-flight hormone.” It\'s released in response to a stressful, exciting, dangerous, or threatening situation. Adrenaline helps your body react more quickly. In response to acute stress, the body\'s sympathetic nervous system is activated due to the sudden release of hormones. The sympathetic nervous systems stimulate the adrenal glands triggering the release of catecholamines, which include adrenaline and noradrenaline. |

What is thyroxine harmone? |
| Answer» Thyroid hormones are two hormones produced and released by the thyroid gland, namely triiodothyronine and thyroxine. They are tyrosine-based hormones that are primarily responsible for regulation of metabolism. T₃ and T₄ are partially composed of iodine. Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones. | |

Describe in brief what happens to zygote when it gets implanted |
| Answer» The zygote formed after fertilization in the fallopian tube is implanted in the uterus. It divides repeatedly to form a mass of cells known as an embryo. This embryo gets attached to the inner layer of the uterine cavity, i.e., endometrium. It thickens every month and is supplied with blood to nourish the embryo. Soon it gets covered by rapidly dir.iding uterine cells. This leads to pregnancy.\xa0Within a span of some months, the embryo starts developing limbs and begins to resemble a miniature human being. When all body parts of the embryo can be recognized, it becomes a fetus. When this fetus is fully developed, the mother\xa0gives birth to the baby. | |

What is line emission spectrum? |
|
Answer» Kost welcome dear ?✌ Thanks for your answers... ya it\'s helpful?✌ The\xa0emission spectrum\xa0of a\xa0chemical element\xa0or\xa0chemical compound\xa0is the spectrum of\xa0frequencies\xa0of\xa0electromagnetic radiation\xa0emitted due to an\xa0atom\xa0or molecule making a\xa0transition\xa0from a high energy state to a lower energy state. The\xa0photon energy\xa0of the emitted\xa0photon\xa0is equal to the energy difference between the two states. There are many possible electron transitions for each atom, and each transition has a specific energy difference. This collection of different transitions, leading to different radiated\xa0wavelengths, make up an emission spectrum. Each element\'s emission spectrum is unique. Therefore,\xa0spectroscopy\xa0can be used to identify elements in matter of unknown composition. Similarly, the emission spectra of molecules can be used in chemical analysis of substances. Hope it will help you ?✌ Hi Sodium emits yellow light while potassium gives out violet light. If this light is resolved in a spectroscope, some isolated coloured\xa0lines\xa0are obtained on the photographic plates separated from each other by dark spaces. This\xa0spectrum\xa0is called\xa0line emission spectrum\xa0on\xa0line spectrum. |

Why the light rays coming from infinity is similar? |
| Answer» We consider\xa0light rays\xa0from\xa0infinity\xa0parallel because they are parallel. ... As the intersection point is pushed further away, the lines become more parallel.\xa0The\xa0object at infinity means\xa0distant\xa0object. The rays falling on the lens from an\xa0object at infinity\xa0are parallel to principal axis.\xa0Object at\xa0infinity\xa0is a fancy way of saying that all the\xa0light\xa0rays coming from the object are parallel(almost) to each other. (Which is practically impossible because the object will emit or reflect\xa0light\xa0in all possible direction). | |

Define oxidising and reducing agents with proper examples |
|
Answer» An oxidizing agent (oxidant), gains electrons and is reduced in a chemical reaction. It is also known as electron acceptor. The oxidizing agent is usually in one of its higher possible oxidation states as it will gain electrons and be reduced.Examples of oxidizing agents are:\tpotassium nitrate\thalogens\tnitric acidA reducing agent (reductant), loses electrons and is oxidized in a chemical reaction.\xa0It is typically in one of its lower possible oxidation states and is known as an electron donor. A reducing agent is oxidized because it loses electrons in the redox reaction.Examples of reducing agents are:\tformic acid\tthe earth metals\tsulfite compounds An oxidizing agent is substance which oxidizes something else. In the above example, the iron(III) oxide is the oxidizing agent. A reducing agent reduces something else. In the equation, the carbon monoxide is the reducing agent.Oxidizing agents give oxygen to another substance.Reducing agents remove oxygen from another substance. |

What is the valency of Phosphorus |
|
Answer» Valency of phosphorus is 3 Phosphorus has valency 3.The valence (or valency) of an element is a measure of its combining power with other atoms when it forms chemical compounds or molecules.In\xa0PH3\u200b, P\xa0is combined to 3\xa0H\xa0atoms, so the valency of phosphorous is\xa0+3. The number of\xa0valence\xa0electrons or the number of electrons in the outermost shell of\xa0phosphorus\xa0is 3. - Thus, one atom of\xa0phosphorus\xa0is capable of combining with three atoms of hydrogen in order to form phosphine (PH3). Therefore, the\xa0valency of phosphorus\xa0in PH3 is +3. |

What is bifocal lens |
|
Answer» Bifocals: A bifocal lens is created with two different areas of vision correction, which are divided by a distinct line that sits horizontally across the lens. The top portion of the lens is used for distance, while the bottom portion of the lens is used for closer vision. Bifocals are eyeglasses with two distinct optical powers. Bifocals are commonly prescribed to people with presbyopia who also require a correction for myopia, hyperopia, and/or astigmatism. |
