What is the function of (a) eye lens, (b) pupil (c) cones and rods |
| Answer» <p>a)By changing its shape, thelenschanges the focal distance of the eye. In other words, it focuses the light rays that pass through it (and onto the retina) in order to create clear images of objects that are positioned at various distances. It also works together with the cornea to refract, or bend, light.</p> <p>b)Theiriscontracts and dilates involuntarily and changes the size of the pupil. The whole job of theirisand pupil is to control the amount of light that gets into the eye.</p> <p>c)</p><p>There are two types of photoreceptors involved in sight: rods and cones.</p><p>Rods work at very low levels of light. We use these for night vision because only a few bits of light (photons) can activate a rod. Rods don't help with color vision, which is why at night, we see everything in a gray scale. The human eye has over 100 million rod cells.</p><p>Cones require a lot more light and they are used to see color. We have three types of cones: blue, green, and red. The human eye only has about 6 million cones. Many of these are packed into the fovea, a small pit in the back of the eye that helps with the sharpness or detail of images.</p> | |

| Answer» <p>(1) Negative</p><p>Explanation:The anode of a galvanic cell is negatively charged, since the spontaneous oxidation at the anode is the source of the cell's electrons or negative charge. However, the anode of an electrolytic cell is positive (cathode is negative), since the anode attracts anions from the solution. </p> | |

2. Explain the soil profile. |
| Answer» <p>The soil profile is one of the most important concepts in soil science. It is a key to understanding the processes that have taken in soil development and is the means of determining the types of soil that occur and is the basis for their classification. The soil profile is defined as a vertical section of the soil from the ground surface downwards to where the soil meets the underlying rock. The soil profile can be as little as 10 cm thick in immature soils and as deep as several metres in tropical areas where the climate is conducive to rapid alteration of the underlying rock to form soil. In temperate areas, the soil profile is often around a metre deep and in arid areas somewhat shallower than this.</p><p>Virtually all soil profiles are composed of a number of distinctive layers, termed horizons, interpretation of which is the key to understanding how the soil has formed. Most soils will have three or more horizons. Soils that have not been cultivated will normally have L, F and H layers at the surface. These layers largely represent different degrees of decomposition of organic matter, the L layer representing thelitter layerformed of recognisable plant and soil animal remains, the F layer below, thefermentation layer, usually consisting of a mixture of organic matter in different stages of decomposition, and the H layer, thehumose layer, consisting largely of humified material with little or no plant structure visible. Below these, and in cultivated soils occupying the surface layer, is the A horizon composed of a more or less intimate mixture of mineral and organic matter. The A horizon is often referred to as the ‘ploughed layer’ in cultivated soils. It is an important part of the soil because it is a source of plant nutrients and contains the majority of plant roots. The A horizon may lie directly on the B horizon or, in well developed soils, there may be an intermediate leached horizon, termed E or A2, depending on the nomenclature system used. The E/A2 horizon is usually paler in colour than the horizons above and below because it is a horizon that has been subject to leaching and loss of components compared to the A and B horizons.</p><p>The B horizon is the horizon most widely used to identify soil types. Its morphology is important in supporting the classification of soils. In some soils the B horizon results purely from the weathering of the underlying rock whereas in other soils this weathering is supplemented by the translocation of materials from overlying horizons. Thus the B horizon needs to be inspected carefully in order to understand the genesis of the soils. B horizons may have a number of different subscripts indicative of the nature of the materials that have moved into the horizon, e.g. Bh indicates the translocation of humus into the horizon, Bs, the translocation of sesquioxides. These subscripts will vary according to the nature of the soil component that has accumulated but also with the system of nomenclature of soil types.</p><p>Below the B horizon is the C horizon. This latter horizon is often consistent with the parent material and may have been little altered from the material in which the soil originally formed.</p><p>Most soils have A, B and C horizons. Some, generally weakly developed, soils may have A horizons lying directly on C horizons. When next you see a profile down through the soil, perhaps in an excavated pit or in a roadside cutting, take time to look at the profile and see if you can identify some of the different soil layers that make up the profile.</p><p>Please hit the like button if this helped you out.</p> | |

II. Define the following.1. Soil profile |
| Answer» <p>A soil horizon is a layer parallel to the soil surface, whose physical, chemical and biological characteristics differ from the layers above and beneath. Horizons are defined in many cases by obvious physical features, mainly colour and texture</p> | |
