Why do stars twinkle but planets do not ???? |
|
Answer» Stars twinkle because they appear as tiny pinpoints as seen from Earth, even through telescopes. Planets don\'t twinkle because they are closer, and thus appear larger in our sky, as tiny disks instead of pinpoints. The planets are much closer to the earth and are thus seen extended sources. If we consider a planet as a collection of a large number of point sized source of light the total variation in the amount of light entering our eye from all the individual point sized sources will average out to zero thereby nullifying the twinkling effect. |

Differences between analogous and homologous organs. |
| Answer» \tHomologous organs:Analogous OrgansHave the same structural design and developmental origin.Have different basic structural design and developmental origin.But they have different functions and appearance.But they have similar appearance and perform similar functions.Example: The forelimb of a frog, a man, a lizard and a frog seem to be built from the same basic design of bones, but they perform different functions.Example: The wings of birds and bats look similar. But in birds wings are covered by feathers all along the arm but the wings of bats are skin folds stretched between elongated fingers.\t | |

what double displacements reaction |
|
Answer» Double displacement reaction is the reaction when both reactive metals displace one another from their place is called double displacement reaction Double displacement reactions may be defined as the chemical reactions in which one component each of both the reacting molecules is exchanged to form the products. During this reaction, the cations and anions of two different compounds switch places, forming two entirely different compounds.Double displacement reactions generally take place in aqueous solutions in which the ions precipitate and there is an exchange of ions.The general equation which represents a double displacement reaction can be written as:AB + CD → AD + CB Because it is salt When two compounds exchange theur ions i n an chemival reaction is called chemical reactions When two coumpounds exchange their coresponding ions in an chemical reaction is known as double displacement reaction. Why NaCl is neutral |

What is. Process ofmechanism of urine formation? |
| Answer» Glomerulus is a tuft of capillaries at the point of origin of each vertebrate nephron that passes a protein-free filtrate to the surrounding Bowman\'s capsule. Glomerulus is a tiny ball-shaped structure composed of capillary blood vessels actively involved in the filtration of the blood to form urine. The glomerulus is one of the key structures that make up the nephron, the functional unit of the kidney.\xa0Different steps involved in the urine formation are\xa0Glomerular filtration, Reabsorption and Secretion.\xa0Glomerular filtration\xa0is the first step in urine formation. Blood comes to the kidney via the renal artery, branches into even smaller arteries and eventually into the afferent arteriole. The afferent arteriole feeds into the glomerulus, providing the blood for the glomerular capillaries.\xa0As the blood travels through these capillaries, filtration causes a lot of the plasma contents to spill out. They spill out of the glomerular capillaries which end up within the glomerular capsule. The glomerular capsule is continuous with the rest of the renal tubules. The solution that spills out in the renal corpuscle is the solution that we will clean out to make urine.\xa0Reabsorption\xa0is the process which involves the reabsorption of valuable solutes and water back into the blood.Secretion\xa0is the third step in urine formation which helps in maintaining the acid-balance of the body. | |

Why the light ray passing though the optical center travels in the same path...............? |
| Answer» Deviation is the change in direction of the ray while passing through the lens. The middle portion of the lens is comparatively flat and there is a point on the principal axis and inside the sphere through which all the undeviated rays pass.“Undeviated” doesn’t mean that there is no refraction. When we say that there is no deviation, we only mean that the incident ray and the emergent ray are parallel to each other. For thin lenses, the refraction inside the lens is negligible and therefore we represent the ray passing through the optic centre as a straight line. But in | |

Which mirror is best suitable for rear-view mirror and solar cooker and why? |
|
Answer» A concave mirror is used in solar cooker because it converges light rays coming from infinity to a point so that more heat is produced at the point sufficient to cook the food.Another name for a concave mirror is a converging mirror, which pretty much sums up their purpose: point all the light that hits them on a singe point (the bit where all they rays actually cross each other is called the focal point). At this point, all the Infra Red radiation that has hit them (and been reflected by the mirror\'s surface) is focussed, and it is this IR radiation that actually does the heating up. Thus, the idea of a solar cooker is to put some food right on top of this focal point to greatly increase the amount of energy that is hitting it, and so heat it up and cook it.Basically, they transfer all the energy that is hitting the large surface of the mirror to a very small spot. Same plane mirror Plane mirror |

What are the post fertilisation changes in plants? |
|
Answer» After fertilisation, the sepals, petals and stamens wither and fall off. In some cases, the sepals remain persistent. The ovules are transformed into seeds, the zygote becomes an embryo and the ovary becomes a fruit.Post-fertilization events refer to all the events of sexual reproduction taking place after fertilization, that is, after the formation of zygote. The major event taking place in this stage is embryo-genesis, that is, development of the embryo which includes:1. Cleavage formation (morula and blastocyst formation)2. Implantation3. Gastrulation Zygote well form after frtilisation and and thise zygote take nutrition from two uppr cell and after it zygote gose to resting period and formation of neuttritive tissue takes plase and zygote active and grow to seed and vegative part grow to frut |

Explain V-I graph Right hand thumb rule Bio ch hereditary & evoulation |
| Answer» Right Hand Thumb Rule: If a current carrying conductor is imagined to be held in your right hand such that the thumb points along the direction of current, then the direction of the wrapped fingers will give the direction of magnetic field lines. Accordingly if current in wire is vertically upward, the magnetic field lines are anticlockwise, while if current in wire is vertically downward, the magnetic field lines are clockwise.V-I graph : After performing experiment for different readings of V & I and recording the observations, if we plot current on the x-axis of a graph and voltage on the y-axis of the graph, we will get a straight-line. The gradient of the straight-line graph is related to the resistance (R) of the conductor. | |

What makes the backbone of DNA?? |
|
Answer» The double helix looks like a ladder that has been twisted at both ends. It is made of three component parts; a sugar, phosphate groups, and nitrogen bases.

Explain nuclear fission reaction in detail ?? |
|
Answer» Thank you yar.......it helped me a lot., The word fission means splitting and breaking up into parts. Thus, nuclear fission reaction involves splitting up of nucleus into parts. Nuclear fission reaction is the reaction in which heat is released in unlimited amount which is very useful for the purposes based on high energy requirement. In this nuclear elements like uranium, plutonium etc. are reacted with low enegy neutrons. After the reaction the heavy atom ( uranium) splits into lighter atoms like barium and krypton with three neutrons and tremendous amount of energy is evolved. |
