Difference between stars and the sun |
|
Answer» sun is a star but allof star is very small yes A\xa0star is\xa0called a "sun" if it\xa0is\xa0the center of a planetary system. A large number of planets have been found that orbit other\xa0stars, thus making these\xa0stars\xa0officially "suns." Chances are that a large percentage of the\xa0stars in the\xa0galaxy also have planets orbiting them, which would make them suns as well.\xa0Most\xa0stars\xa0are very\xa0similar to\xa0our\xa0sun. In fact the\xa0sun\xa0is a pretty normal kind of star. It\'s much brighter than the other\xa0stars\xa0because it is close by. Even the closest star (other than the\xa0sun) is very far away. |

Full structure of eye. |
| Answer» The various parts of the human eye and their respective functions include:\tCornea – It helps the light to enter the eyes coming through various objects.\tIris – It controls the amount of light entering in to the eyes.\tPupil – It is a hole in middle of iris which adjusts its opening to allow the required amount of light for clearing purpose.\tCiliary muscles- The focal length of the eyes is changed by the action of ciliary muscles. The ciliary muscles can change the thickness of the soft and flexible eyes lens and hence the focal length which, in turn, changes the converging power of the eyes.\tEye-lens – It forms the real image of the object on the retina.\tRetina – It is a screen on which the image is formed.\tOptic nerve – These nerves transfers the formed image to the brain. | |

Part of brain with their functions |
| Answer» The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus . The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons and medulla.Cerebrum: The cerebrum is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebral cortex is divided into four sections, called "lobes": the frontal lobe, parietal lobe, occipital lobe, and temporal lobe.\tFrontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving\tParietal Lobe- associated with movement, orientation, recognition, perception of stimuli\tOccipital Lobe- associated with visual processing\tTemporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speechThalamus-It is a large mass of gray matter deeply situated in the forebrain at the topmost portion of the diencephalon. The structure has sensory and motor functions. Almost all sensory information enters this structure where neurons send that information to the overlying cortex.Hypothalamus-It is a part of the diencephalon, ventral to the thalamus. The structure is involved in functions including homeostasis, emotion, thirst, hunger, circadian rhythms, and control of the autonomic nervous system. It also controls the pituitary.Midbrain- It is involved in functions such as vision, hearing, eyemovement, and body movement.Cerebellum - The cerebellum has two hemispheres and has a highly folded surface or cortex. This structure is associated with regulation and coordination of movement, posture, and balance.Pons- It is involved in motor control and sensory analysis. It has parts that are important for the level of consciousness and for sleep.Medulla Oblongata- This structure is present between the pons and spinal cord. It is responsible for maintaining vital body functions, such as breathing and heartrate. | |

Difference between DC and AC? |
||
| Answer» | | | \tAC can carry and safe to transfer longer distance even between two cities, and maintain the electric power.DC cannot travel for a very long distance. It does, it loses electric power.The rotating magnets cause the change in direction of electric flow.The steady magnetism makes DC flow in a single direction.The frequency of AC is depended upon the country. But, generally, the frequency is 50Hz or 60Hz.DC has no frequency of zero frequency.In AC the flow of current changes its direction backwards periodically.It flows in a single direction steadily.Electrons in AC keep changing its directions – backward and forwardElectrons only move in one direction – that is forward.\t|

डिफरेंस between meiosis and mitosis |
|
Answer» \tMitosisMeiosisEach chromosome replicates. The result is two genetically identical sister chromatidsChromosomes not yet visible but DNA has been duplicated or replicatedProphase I – crossing-over recombination – Homologous chromosomes (each consists of two sister chromatids) appear together as pairs. Tetrad is the structure that is formed. Segments of chromosomes are exchanged between non-sister chromatids at crossover points known as chiasmata (crossing-over)Prophase –Each of the duplicated chromosomes appears as two identical or equal sister chromatids, The mitotic spindle begins to form. Chromosomes condense and thickenMetaphase I Chromosomes adjust on the metaphase plate. Chromosomes are still intact and arranged as pairs of homologuesMetaphase -The chromosomes assemble at the equator at the metaphase plateAnaphase I Sister chromatids stay intact. However, homologous chromosomes drift to the opposite or reverse polesAnaphase – The spindle fibres begin to contract. This starts to pull the sister chromatids apart. At the end of anaphase, a complete set of daughter chromosomes is found each poleAsexual ReproductionSexual ReproductionEukaryotic cellsDiploid cellsGeneral growth and repair, Cell reproductionGenetic diversity through sexual reproduction\t Mitosis involves the division of body cells, while meiosis involves the division of *** cells. ... Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis. Daughter cells resulting from mitosis are diploid, while those resulting from meiosis are haploid. |

What are trends in modern periodic table |
|
Answer» Thanks Trends in the modern periodic table\tThe number of shells increases on going down the group.\tThe number of valence shell electrons increases with the increase in atomic number on moving from left to right in a period with each period marking the filling of a new electronic shell.\tAtomic size decreases in moving from left to right along a period due to an increase in nuclear charge pulling the electrons closer to the nucleus.\tAddition of new shells down the group increases the distance between the outermost electrons and the nucleus thereby increasing the atomic size down the group.\tAcross a period effective nuclear charge acting on the valence shell electrons increases which decreases the tendency to lose electrons. Hence metallic character decreases and non-metallic character increases across a period.\tDown the group, the effective nuclear charge decreases which increases the tendency to lose electrons. Hence metallic character increases and non-metallic character decreases down a group. Major periodic trends include: electronegativity , ionization energy , electron affinity , atomic radius , melting point, and metallic character . |

What is Tyndall effect name five place where we can see it |
| Answer» The\xa0Tyndall effect\xa0is\xa0scattering of light\xa0by particles in a\xa0colloid\xa0or particles in a fine\xa0suspension. It can be seen when the light passes through the colloids or turbid substances\xa0causing the light to scatter in multiple directions. Examples are:\tA blue\xa0iris\xa0in an eye is due to Tyndall scattering in a\xa0turbid\xa0layer in the iris.\xa0\tThe Tyndall effect in\xa0opalescentglass: It appears blue from the side, but orange light shines through.\tLight being shined through milk. As milk is a collloid.\tOn a day when the sky is overcast, the sunlight passes through the turbid layer of the clouds, resulting in scattered,\xa0diffuse light on the ground.\xa0\tFog because it is a colloidal substance. When light hits a substance with scattered particles, it collides with the particles, causing the light to scatter in multiple directions.\tThe tyndall effect can be observed when the sunlight passes through the canopy of a dense forest.\xa0\tThis effect can also be seen when the sun sets as the sky changes color depending on how low the sun is and as a result how much atmosphere the sun\'s light must pass through.\tThe blue colour of smoke coming out from a 2 stroke engine, or even a four stroke engine where the burnt engine oil provides the particles.\tThe Tyndall Effect is also the reason why the sky blue. | |

Why electric current is a scaler quantity? |
|
Answer» Electric current is a scalar quantity. Any physical quantity is termed as a vector quantity when the quantity has magnitude and direction. But there are other factors that determine the quantity as vector or scalar quantity. If the physical quantity obeys the laws of vector addition such as triangle law of vector addition and parallelogram law of vector addition, then the quantity is said to be a vector quantity.In the case of electric current, when two currents meet at a junction, the resultant current of these will be an algebraic sum and not the vector sum. Therefore, an electric current is a scalar quantity although it possesses magnitude and direction. Electric current is a scaler quantity although it possesses magnitude and direction.☺️☺️ Because it have both direction as well as magnitude |
