Mechanism of Vision |
|
Answer» Light rays enter the eye through the cornea, the clear front “window” of the eye. The cornea’s refractive power bends the light rays in such a way that they pass freely through the pupil the opening in the center of the iris through which light enters theeye. The iris works like a shutter in a camera. It has the ability to enlarge and shrink, depending on how much light is entering the eye. After passing through the iris, the light rays pass thru the eye’s natural crystalline lens. This clear, flexible structure works like the lens in a camera, shortening and lengthening its width in order to focus light rays properly. Light rays pass through a dense, transparent gel-like substance, called the vitreous that fills the globe of the eyeball and helps the eye hold its spherical shape. In a normal eye, the light rays come to a sharp focusing point on the retina. The retina functions much like the film in a camera. It is responsible for capturing all of the light rays, processing them into light impulses through millions of tiny nerve endings, then sending these light impulses through over a million nerve fibers to the optic nerve. Because the keratoconus cornea is irregular and cone shaped, light rays enter the eye at different angles, and do not focus on one point the retina, but on many different points causing a blurred, distorted image. In summary, the cornea is the clear, transparent front covering which admits light and begins the refractive process. It also keeps foreign particles from entering the eye. The pupil is an adjustable opening that controls the intensity of light permitted to strike the lens. The lens focuses light through the vitreous humor, a clear gel-like substance that fills the back of the eye and supports the retina. The retina receives the image that the cornea focuses through the eye’s internal lens and transforms this image into electrical impulses that are carried by the optic nerve to the brain. We can tolerate very large scars on our bodies with no concern except for our vanity. This is not so in the cornea. Even a minor scar or irregularity in the shape can impair vision. No matter how well the rest of the eye is functioning, if the cornea is scarred, clouded or distorted, vision will be affected. In keratoconus, the irregular shape of the cornea does not allow it to do its job correctly, leading to distortion of the image it passed to the retina and transmitted to the brain. thank u very much |

Blood from the lungs comes into:(a) Right atrium(c) Right ventricle(b) Left atrium(d) Left ventricle |
|
Answer» Answer : b) Left atriumExplanation :Blood entersthe heart through two large veins, the inferior and superior vena cava, emptying oxygen-poorbloodfrom the bodyintothe right atrium. The pulmonary vein empties oxygen-richblood, from thelungs intothe left atrium. |
|
| 4068. |
How do you account for the following differences(a) The left ventricle has thicker walls than the rightventricle.(b) The walls of the right ventricle are thicker than thoseof the right auricle. |
|
Answer» a)ventricles have thicker walls than the atria and generate higher blood pressures _ _ further , the left ventricles has thicker walls than the right because it need to pump blood to most of the body while the right ventricles fills only the lungs. (a) The left ventricle has thicker walls than the right because it pumps blood throughout the body, while the right ventricle pumps only to the lungs, which is a much smaller volume of blood. During ventricular systole, the ventricles contract, pumping blood through the semi-lunar valves into systemic circulation. (b) Ventricles have thicker walls than auricle because they have to do more work. On the right and left sides of the heart, the auricle act as receiving chambers for incoming blood. The ventricles, on the other hand, have to pump the blood out of the heart. |
|
| 4069. |
why ventricle have thicker walls than auricle |
|
Answer» The ventricles of the heart have thicker muscular walls than the atria. This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria. The left ventricle also has a thicker muscular wall than the right ventricle, |

53. What happens to waste generated at home! |
|
Answer» The following incident happens when waste generated at home :-1) It creates many diseases like malaria due to coming of denserous mosquitos.2) There are many housefly flying above that waste materials which are again flying on our foods items, this also creates diseases. Every home generates both organic and inorganic waste and managing this waste on a daily basis calls for some planning as collection and disposal are integral parts of its management. If you collect waste, it needs to be disposed else it would lead to serious repercussions on health and other social problems.In the home perspective waste or garbage is of three types:Organic waste, Toxic waste and Recyclable waste.Organic wasteOrganic waste, or green waste, is organic material such as leftover food (both vegetarian and non-vegetarian), fruit and vegetable peels, garden and lawn clippings, egg shells, etc. These are also bio-degradable. About a third of the home waste produced is categorised as organic waste. This can easily be made into reusable, high quality compost if treated properly at home. On the other hand if this bio-degradable organic waste is dumped into landfill sites, it decays and in the process produces methane gas which is extremely harmful to the environment and may cause unpredictable explosions.Toxic wasteToxic waste are old medicines, paints, chemicals, bulbs, spray cans, fertilizer and pesticide containers, batteries, shoe polish.Recyclable wasteRecyclable: paper, glass, metals, plastics.Toxic and recyclable wastes are also called inorganic waste. These are not biodegradable and one has to be careful in disposing it. Careless dumping of these materials in open grounds could contaminate the soil and cause serious damage to environment and to life.There is a further category of waste called e-waste or Electronic waste. These are used electronic parts which, most certainly, are destined for reuse, resale, salvage, recycling or disposal. Unfortunately, there is no law to monitor and check the disposal of e-waste.Electronic waste like CRTs, most certainly, contain contaminants such as lead, cadmium, brominated flame retardants and other hazardous chemicals which, if not scientifically disposed or recycled, poses great danger to the health of the workers involved in this exercise.Home waste management involves the following processes:Collection, transport and disposal of wasteEvery day, garbage like kitchen waste, paper wrappers, bottles, both glass and plastic, is collected in the home. In the cities, very often you have the garbage collectors, appointed by the city corporation or other similar bodies, who either collect the garbage from your home or from designated bins. These are then transported to a central area from where the further process of disposal takes place.So far, so good; what happens when this collection does not happen? The garbage then accumulates in the house and unless it is disposed, it becomes a breeding ground for ants, cockroaches, mosquitoes and even rodents. Consequently, it could lead to many health issues, especially when there are young children in the house.Disposing the inorganic waste can be done at one’s convenience since it does not decay but not so with the organic waste. This brooks no delay.So how does one go about managing it effectively?1. Minimise the collection and accumulation of garbage by avoiding bringing in plastic bags. Don’t let garbage accumulate at home. Regular disposal will keep insects like cockroach, ants and flies away. These insects breed in garbage.2. Use reusable cloth bags for your shopping.3. Avoid bringing in goods that has multi-layered packaging. Readymade garments get packed in many layers of plastic and plastic coated wrappings. Once you have purchased the item try and remove all the packing in the store itself, unless it is a gift item.4. Segregate the garbage into organic and inorganic collection bins. Do not put them in the same bin.5. Try composting the organic garbage. The internet can help you with ideas on how to compost. This will not only help in the disposal but also get you valuable compost for your kitchen garden, thus saving you some money.6. Lastly, give up the habit of hoarding. Most of us are prone to this. Donate you old clothes and utensils to orphanages or other institutions that may be in need of this. But make sure that you give away only those items that are usable, and do not donate torn clothes or badly damaged utensils. These can go to the raddiwala.If every house conscientiously disposes the garbage they collect, this stinking problem can be safely solved. It is also incumbent on the individual to create awareness in others in the neighbourhood to follow such appropriate methods to keep each living unit, building and the neighbourhood clean.Stanley Varghese for IndiaProperty.comImage author: |

what are chemical properties of solid waste |
|
Answer» CHEMICAL CHARACTERISTICS Information of chemical characteristics is important in evaluating alternative processing and recovery options. Typically waste is considered as combination of combustible and noncombustible components. If solid waste is to be used as a fuel or for any other use we should know its chemical components. Lipids These are included in the class of fats, oils and grease. The principal sources of lipids in the garbage are cooking oil and fats. Lipids have high heating values about 38,000 Kj/Kg (kilojoules/kilograms), which makes the waste with high lipid content suitable for energy recovery. Since lipids become liquids at temperature slightly above ambient they add to the liquid content during waste decomposition. They are biodegradable, but they have low solubility in water and hence the rate of biodegradation is slow. Carbohydrates These are primarily originated from the food sources rich in starch and celluloses. These readily biodegrade into carbon dioxide, water and methane. Decomposition of carbohydrates attracts the flies and rats and hence should not be left exposed for long duration. Proteins These are the compounds containing carbon, hydrogen, nitrogen and oxygen and organic acid with amino groups. They are primarily found in food and garden wastes, but their partial decomposition result in the production of amines, which impart unpleasant odors. Natural Fibers These are the natural products contain cellulose and lignins that are relatively resistant to biodegradation. These are found in paper products, food and yard wastes. Paper is almost100% cellulose, cotton over 95% and wood products over 40-50%. These are highly combustible products most suitable for incineration. The calorific value of oven dried paper products are in the range 12000-18000 kj/kg. Synthetic Organic Materials In the recent years plastics have become a significant components of solid waste, accounting for 1-10%. They are highly resistant to the biodegradation; hence their presence in the waste is objectionable. Currently much attention is given to reduce this component at disposal sites. Plastics have a high heating value, about 32000 kj/kg, which makes them very suitable for incineration. However, among the plastics Polyvinyl chloride (PVC) when burnt produces dioxin and acid gas. The trace gases produced during the burning of plastic are proved to be carcinogenic. |

Explain perental care in amphibians |

Answer» PARENTAL CAREIN THE MEMBERS OF CLASSAMPHIBIA.Amphibianinclude anurans, urodelans and apodans. ...Amphibiansshow several mechanisms to protect their eggs and developing young ones because of the they lay few eggs. Parents protect the eggs and early developmental stages in two ways. PARENTAL CAREIN THE MEMBERS OF CLASSAMPHIBIA.Amphibianinclude anurans, urodelans and apodans. ...Amphibiansshow several mechanisms to protect their eggs and developing young ones because of the they lay few eggs. Parents protect the eggs and early developmental stages in two ways. Despite the fascinating parental care behaviors exhibited by amphibians, relatively few quantitative studies have been published on this class in comparison to birds and mammals. Six modes of parental care are recognized: egg attendance, egg transport, tadpole attendance, tadpole transport, tadpole feeding, and internal gestation in the oviduct. Whereas egg attendance and internal gestation in the oviduct are the only modes of parental care known for caecilians and salamanders, anurans display all six modes. Although parental care is widely distributed phylogenetically within the Amphibia, the percentage of species providing care is low. Postoviposition parental care has been documented in only about 5% of caecilians, 18% of salamanders, and 6% of anurans. Internal gestation in the oviduct probably occurs in about 75% of all caecilians, in 4 species of salamanders, and in 5 species of anurans. Parental care in amphibians is most commonly found in geographical areas of correspondingly high species richness. PARENTAL CAREIN THE MEMBERS OF CLASSAMPHIBIA.Amphibianinclude anurans, urodelans and apodans. ...Amphibiansshow several mechanisms to protect their eggs and developing young ones because of the they lay few eggs. Parents protect the eggs and early developmental stages in two ways. Amphibianincludeanurans, urodelans and apodans. In all these groups of amphibians we come across with a great deal of parental care. Amphibians show several mechanisms to protect their eggs and developing young ones because of the they lay few eggs. Parents protect the eggs and early developmentalstagesin two ways. They construct nestsDirect Nursing. The female Icthyophis glulinosa will dig a hole in the moist soil near a pond. It will deposit eggs in it. Around this egg mass the mother will coil and. protect the egg mass from the enemies. Inbiology, paternal care isparental investmentprovided by amaleto his ownoffspring. It is a complex social behaviour in vertebrates associated with animal mating systems, life history traits, and ecology. Paternal care may provided in concert with the mother (biparental care) or, more rarely, by the male alone (so called exclusive paternal care). The provision of care, by either males or females, is presumed to increase growth rates, quality, and/or survival of young, and hence ultimately increase theinclusive fitnessof parents.In a variety of vertebrate species (e.g., about 80% of birdsband about 6% of mammals), both males and females invest heavily in their offspring. Many of these biparental species are sociallymonogamous, so individuals remain with their mate for at least one breeding season. Paternal care occurs in a number of species of anuran amphibians,[46]includingglass frogs.Exclusive paternal care has evolved multiple times in a variety of organisms, including invertebrates, fishes, and amphibians Parental Care in Amphibians.Parental caremay bedefinedas all activities that are directed by an animal towards the protection and maintenance of its own offspring or those of a near relative. By comparison with birds and mammals,amphibiansgenerally have been thought to exhibit littleparental care. |

what are physical properties of solid waste |
|
Answer» Physical Characteristics Moisture content: Moisture content is a critical determinant in the economic feasibility of waste treatment by incineration since energy must be supplied for evaporation of water and in raising the temperature of the water vapour. Moisture content also plays an important role in other processing methods such as composting and anaerobic digestion. Particle size: The measurement of the size distribution of particles in the waste stream is important because of its significance in the design of mechanical separators and shredders. The results of the analysis are expressed in the manner used for the particle analysis of soils namely a plot of particles size against % less than a given value. Density: Knowledge of the density of waste i.e. mass per unit volume is essential for the design of all elements of the solid waste management system. For example, in high income countries, considerable benefit is derived through the use of compaction vehicles on collection routes, because the waste is typically of low density. However, in India and other developing countries such as Thailand, Indonesia etc. due to higher initial density the compaction ratio obtained rarely exceeds 1.5. Field capacity: Field capacity of solid waste is total amount of moisture that can be retained in waste sample subject to downward pull of gravity. Field capacity of critically important in determining the formation of leachate in landfills. Water excess of field capacity can be released as leachate and field capacity varies with degree of applied pressure and state of decomposed moisture of waste. Permeability: The Hydraulic conductivity of compacted waste is an important physical property to a large extent governs movement of liquid and gases in landfill. |

|
Answer» Anaerobic respirationisrespirationusingelectron acceptorsother thanmolecular oxygen(O2). Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain.[1] Inaerobic organismsundergoing respiration, electrons are shuttled to anelectron transport chain, and the final electron acceptor is oxygen.Molecular oxygenis a highlyoxidizing agentand, therefore, is an excellent electron acceptor. Inanaerobes, other less-oxidizing substances such assulphate(SO42−),nitrate(NO3−),sulphur(S), orfumarateare used. These terminal electron acceptors have smallerreduction potentialsthan O2, meaning that less energy is released per oxidized molecule. Therefore, generally speaking, anaerobic respiration is less efficient than aerobic. |
