Why do we dream? |
| Answer» We spend around a third of our lives sleeping. Considering how much time we spend doing it, you might think we’d know everything about it. But scientists are still searching for a complete explanation of why we sleep and dream. Subscribers to Sigmund Freud’s views believed dreams were expressions of unfulfilled wishes – often sexual – while others wonder whether dreams are anything but the random firings of a sleeping brain. Animal studies and advances in brain imaging have led us to a more complex understanding that suggests dreaming could play a role in memory, learning and emotions. Rats, for example, have been shown to replay their waking experiences in dreams, apparently helping them to solve complex tasks such as navigating mazes. | |

What is animals tissues explin |
| Answer» \tAnimal tissues are grouped into four basic types – epithelial, connective, muscular and nervous tissue.\tBased on the shape and function of its cells, epithelial tissue is subdivided further into squamous, cuboidal, columnar, ciliated and glandular.\tBlood, bone, ligament, tendon, cartilage, areolar tissue and adipose tissue are important connective tissues present in our body.\tFunctions of protection, providing skeletal framework and anchoring are carried out by the strong and hard bone tissue.\tCartilage provides support and flexibility to the body parts.\tBlood is a fluid connective tissue, composed of plasma and blood cells, and plays a significant role in the process of transportation. | |

Prove that time of ascend= time of desend (numerically) |
|
Answer» Thanku Time of Ascent:The time taken by body thrown up to reach maximum height h is called as time of ascent.Let t₁ be time of ascent.at maximim height , its velocity is zero, V=0hence , V=u-gt0=u-gt₁t1=u/g ------------- (1)Time of descent:after reaching the maximum height, the body begins to travel downwards and reaches the ground.The time taken to by a freely falling body to touch the ground is called time of descent.Initial velocity for downward journey is zero , u= 0let t₂ be time of descent.s=ut+1/2 gt²h=0+1/2gt₂²t2=√2h/gbut, h=u²/2gso, we gett₂=√2u²/2g =u/g---------------(2)from equation 1 and 2 we can sayt₁=t₂the time of ascent is equal to time descent in the case of bodies moving under gravity. |

Give at least 5or 6 different b/w mitosis and meiosis???? |
| Answer» \tTypesMitosisMeiosisInterphaseEach chromosome replicates. The result is two genetically identical sister chromatidsInterphase – Chromosomes not yet visible but DNA has been duplicated or replicated.ProphaseProphase 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 thickenMetaphaseMetaphase 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 plateAnaphaseAnaphase I Sister chromatids stay intact. But homologous chromosomes drift to the opposite or reverse poles.Anaphase – 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 pole.Types of ReproductionAsexualSexualOccurs inEukaryotic cellsDiploid cellsFunctionGeneral growth and cell reproduction, repair of the body.Genetic diversity through sexual reproductionCytokinesisOccurs in TelophaseOccurs in Telophase I and in Telophase II.KaryokinesisOccurs in Interphase.Occurs in Interphase IDiscovered byWalther FlammingOscar Hertwig\t | |

Is the unifirm circular motion accelerated ?give reasons for your answer |
|
Answer» Yes uniform circular motion is accelerated because velocity is changing at every point which is given as a tangent to the circle Yes , uniform circular motion is accelerated because the velocity changes due to continuous change in the direction of motion. So, even when the body moves ta a constant speed, its velocity is not constant. Thus, for a body moving in a circular path at a constant speed, its velocity changes continuously. The change in velocity gives rise to an acceleration in the moving body. Therefore circular motion is an acceleration motion even when the speed remains constant. |
