The fatty nature of myelin is RESPONSIBLE for the GLISTENING whiteness of the peripheral nerve trunks and WHITE matter of the CNS. Thinner AXONS, of less than one micron DIAMETER, do not have the myelin sheath and are therefore termed non-myelinated or non-medullated.

22. Prove that the total energy of a falling object is the same at every point of its font​

Answer»

tion:HELLO friends PLS find the answer below law of conservation of energy states that the energy can neither be created nor be DESTROYED but can be transformed from one form to another....let us now PROVE that the above law holds good in the case of a freely falling body....let a body of mass m placed at a HEIGHT h above the ground, start falling down from rest...in this case we have to show that the total energy ( potential energy + kinetic energy) of the body at A, B and C remains constant i.e, potential energy is completely transformed into kinetic energy...AT A-- potential energy=mgh kinetic energy= 1/2mv square = 1/2*m* 0 kinetic energy= 0 ( the velocity is zero as the object is initially at rest)./// total energy at a = potential energy + kinetic energy = mgh + 0 Total energy at a= mgh ............1eq.....AT B -- potential energy= mgh=mgh( h- x ) height from the ground is ( h-x) potential energy= mgx kinetic energy= 1/2mv square the body covers the distance x with a velocity vv. we make use of the third equation of motion to obtain velocity of the body.....v2- u2u2= 2a here, u=0, a=g, s=xv2- 0= 2 ax here, u= 0 ,a= g and s= xv2 - 0= 2gx..v2 = 2gx kinetic energy= 1/2mv square= 1/2m2gx..kinetic energy= mgxTotal energy at b= potential energy+ kinetic energy= mgh- mgx+ mgx Total energy at B = mgh.....2eq....AT C :- potential energy = m x g x 0 ( h = 0 ) potential energy = 0 kinetic energy =1/2mv2 the distance covered by the body is hv2 - u2 = 2as here, u = 0 ,a= g, and s= h v2 - 0= 2ghv2 = 2gh kinetic energy = 1/2mv2 = 1/2* 2gh total energy at C = potential energy + kinetic energy = 0 + mgh Total energy at C = mgh....3eq....its clear from equation 1,2 and 3 that the total energy of the body remains constant at every point..thus, we conclude that law of conservation of energy holds good in the case of a freely falling body....hope this helps uh......plzz mark it as brainliest....click on thnxxxx rate this answer......follow me guys..........

In this lab, we discussed preparation of a wet mount slide. Research and describe another slide preparation and an example of when it would be used.

Answer»

Used for aquatic samples, living organisms and natural observations, wet mounts SUSPEND specimens in fluids such as water, brine, glycerin and immersion oil. A wet mount requires a liquid, tweezers, pipette and paper towels. To prepare the slide: Place a drop of fluid in the center of the slide Position SAMPLE on liquid, using tweezers At an angle, place one side of the cover slip against the slide making contact with outer edge of the liquid drop Lower the cover slowly, AVOIDING air bubbles Remove excess water with the paper towel Although wet mounts can be used to prepare a significantly wide range of microscope slides, they provide a transitory window as the liquid will dehydrate and living specimens will die. Organisms such as protozoa may only live 30 minutes under a wet mount slide; applying petroleum jelly to the outer edge of the cover slip creates a seal that may extend the life of the slide up to a few days. In addition, larger protozoan such as paramecium may be too large and/or move too quickly under the wet mount. In these circumstances, adding ground pieces of cover glass to the water before the slip layer will create added space and chemicals or strands of cotton can be added to slow the MOVEMENT of paramecium, amoeba and ciliates. Smear Slides: Smear slides require two or more flat, plain slides, cover slips, pipette and tissue paper: Pipe a liquid sample such as blood or slime onto a slide Using the edge of the second slide, slowly smear the sample creating a thin, even coating Put a cover slip over the sample, careful not to trap air bubbles Remove excess liquid Ideally, smears should dry naturally in an environment of moderate, steady temperature. The angle of the smearing slide determines the length of the smear; a steeper angle creates a shorter smear. For samples such as blood, begin by backing the smearing slide into the sample and then push across the slide, pulling the blood in the opposite direction to create a smooth layer. A thicker slide can be created with two drops, but only with the blood of mammals as the erythrocytes lack a nucleus allowing cells to be amassed in multiple layers. Read further about Blood Smears - process and technique, possible presence of artifacts Squash Slides: Designed for soft samples, squash slides begin by preparing a wet mount; place lens tissue over the cover glass; gently press down, careful not to destroy the sample or break the cover glass, and squash the sample; remove excess water. Staining: A variety of methods exist for staining microscope slides, including non-vital or in vitro stains of non-living cells and vital or in vivo stains of living tissue. Staining provides contrast through color that reveals structural details undetected in other slide preparations. Staining solutions such as iodine, methylene blue and crystal violet can be added to wet or dry mounts. A simple staining method: Add a drop of staining solution on the edge of one side of the cover slip Position the edge of a paper towel on the opposite end Allow dye to be pulled across the specimen Stains are especially useful in the fields of histology, virology and pathology, allowing researchers to study and diagnose diseases, identify gram positive and negative bacteria as well as examine detailed attributes of a variety of cells. See different staining types and preparation techniques for more information. Prepared Slides Especially useful for educational purposes and for those who do not want to undertake the laborious process of creating slides, prepared microscope slides are available in all areas of science, including: Biology Plants Animals Single-cell organisms preparing microscope slides Human Anatomy Organ samples Tissues Blood Epithelium cells Botany Monocot and Dicot Tissues Zoology Samples from various animal species Marine-biology Bacteria Algae Coral Fish and Crustaceans Pathology Bacteria Virus Diseased tissue Prepared microscope slides also offer access to bacteria, animal tissue, marine life, diseased cells and other specimens that may not be easily available to students or hobbyists. In addition, they can be used as controls for students and researchers to compare collected samples. Prepared slides can be purchased in sets and are almost always permanent, providing indefinite reuse.   Whether you mount samples, pipette into wells or use prepared slides, microscope slides offer a vehicle to contain a specimen while observing under magnification. Illuminated on the stage of a compound light microscope, an AMAZING new view into the world can be seen with the simple act of placing a sample on a glass slide.  Explanation:

what are plastids? what are three type of plastids and where are they found? ( I WILL MAR THE 1ST ANSWER AS THE BRAINLIST )​

Answer»

tids that semi autonomous organelles having it's own DNA and ribosomes. They are double membranes and basically found in the plant cell. Depending upon the colour and functions, the platids are of THREE TYPES:Chloroplast ChromoplastLeucoplastAs I have mentioned before, there are three types of plastids, Let's know something about them.- The green coloured plastics which contains chlorophyll that helps in trapping solar energy for photosynthesis are known as Chloroplast. The chloroplast is the kitchen of the cell. The chloroplast are found in Mesophyll cells of leaf. These are the site of photosynthesis. The thylakoids are structures present in the grana of chloroplast. They store chlorophyll on their thylakoid membrane. Function - Performing photosynthesis.- The coloured plastids having pigments other than green are known as Chromplast. These are found in the BRIGHTER and colourful parts like flowers. SEVERAL pigments found in chromoplast are Xanthophyll, Carotene etc.Function - Attracting insects for pollination. - They occur in non green, underground parts like the roots. They are colourless and storage sacs and also on the basis of substances they store, they are of three types:Amyloplast - STORES carbohydrates Aleuroplast - Stores proteinsElaioplast - Stores oils and lipids.Function - Helps in storage.━━━━━━━━━━━━━━━━━━━━
