Diabetes mellitus is a condition in which the pancreas no longer produces enough insulin therefore by drinking water more frequently diabetic person and urinate frequently as their bodies try to get rid of the extra glucose.

The inner glass layer expands when hot water is poured into it while the outer layer is still cool, hence the glass cracks.

Bioreserve is a unique kind of protected area that is used for conservation of genetic resources, species, and ecosystems, scientific research and monitoring in addition to promoting sustainable development in communities of the surrounding region. The management system of a biosphere reserve requires being open and adaptable to changes in local circumstances..

Satellites are in the exosphere layer of the atmosphere. This is the layer where our atmosphere merges with space. The ionosphere is defined as the layer of the Earth's atmosphere that is ionized. The ionosphere represents less than 0.1% of the total mass of the Earth's atmosphere. Even though it is such a small part, it is extremely important.

Sunderlal Bahuguna is a noted Garhwali environmentalist, Chipko movement leader and a follower of Mahatma Gandhi's philosophy of Non-violence and Satyagraha. This idea of chipko movement was of his wife and the action was taken by him.

Surface tension of water is a contractive tendency of the surface of a liquid that allows it to resist an external force. It is revealed, for example, in the floating of some objects on the surface of water, even though they are denser than water, and in the ability of some insects (e.g water striders to run on the water surface. This property is caused by cohesion of similar molecules and is responsible for many of the behaviors of liquids..

Jupiter has the most satellites {moons} it has 63 satellites.

Pasteurization refers to the process of heating food normally a liquid to a particular temperature for an exact length of time then cooling it immediately. This process slows spoilage because of microbial growth in the food.

The earth rotates on its axis from west to east. The axis is an imaginary line passing through the northern and the southern poles of the earth. The rotation of the earth is completed in about 24 hours and it is called the daily motion of the earth. This motion is responsible for the occurrence of day and night..

Lichens are extremely sensitive to pollutants in the atmosphere and can be used as bioindicators of air quality. They absorb minerals from the air, from rainwater, and directly from their substrate. Lichen growth has been used as an indicator of air pollution, especially sulfur dioxide. Pollutants are absorbed by lichens, causing the destruction of their chlorophyll, which leads to a decrease in the occurrence of photosynthesis and changes in membrane permeability. Pollutants upset the physiological balance between the fungus and the alga or cyanobacterium, and degradation or destruction of the lichens results. Lichens are generally absent in and around cities, even though suitable substrates exist; the reason for this is the polluted exhaust from automobiles and industrial activity. They are beginning to disappear from national parks and other relatively remote areas that are becoming increasingly contaminated by industrial pollution. The return of lichens to an area frequently indicates a reduction in air pollution.

Compound eyes means that they see through many lenses set in one eyeball, allowing sight from many directions. Many flying insects possess this characteristic. Two eyeballs  and many lenses.

Avian influenza- known informally as avian flu or bird flu refers to 'influenza caused by viruses adapted to birds. The version with the greatest concern is highly pathogenic avian influenza (HPAI)

Birds do not have diaphragm whereas bats do have diaphragm.

Photosynthesis is the biochemical process in which light energy is absorbed by chlorophyll and used to build sugar from carbon dioxide and water, releasing oxygen. The process occurs  in green parts of the plant mostly leaves. In some plants stem may be modified hebaceous to perform photosynthesis.

Tube within-a tube-plan: This type of body plan is found in more complex animal groups. The animals with this body plan posses a digestive canal having two openings at the ends. The openings at the anterior end is mouth through which food enters the digestive canal, at the posterior end anus is present meant for ingestion of undigested waste matter. The digestive canal; is present inside the body cavity and hence, this body plan is termed as the tube within a tube.

The surface tension of liquid is responsible for that ,the tension at surfaces of a drop acts inwards to the center so drop tends to reduced its volume and the minimum possible volume for matter is a sphere and therefore a falling drop of liquid acquires the spherical shape.

Graphite is one of the most common allotropes of carbon. Unlike diamond, graphite is an electrical conductor, and can be used, for instance, as the material in the electrodes of an electrical arc lamp. Graphite holds the distinction of being the most stable form of carbon under standard conditions. Therefore, it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds and this is also use as lead in pencil..

All the above are correct answer.

All the above options are correct.

Saponification is a process that produces soap, usually from fats and lye. .

The scion is a cutting that is located on the sides of the plant. This cutting is most commonly grafted onto the root system of another plant. The scion is selected to be cut especially for its flowers, stems, leaves, flowers and fruits. The genes in the scion are able to be duplicated by the scion plant.

The process of growing plants in sand, gravel, or liquid, with added nutrients but without soil..

The longest cells are neurons (nerve cells ) with a length of 90cm-100cm linking the central nervous system (brain and spinal cord) to other parts of the body. For example, for every receptor cell in your feet, there is a sensory neuron extending from the foot to the base of the spine..

Hard water is caused by the presence of minerals mainly calcium and magnesium in it. The minerals get into the water if it passes through soft rocks like chalk or limestone. If water passes through hard rocks like granite or through peaty soils, it does not pick up these minerals therefore remains soft.

White light is made up of 7 colors. Red colour, due to its longer wavelength does not get scattered by the particles in the atmosphere n hence reaches our eyes more distinctly than the other colors minus much scattering. Green gets scatterd more red but less than blue, which r d basic colours. Hence, red is used 4 stop n danger while green if for GO!</span>.</p>.

Kinetic energy is the one half the mass multiplied by the square of the velocity, K=1/2mv². If mass is doubles, the kinetic energy doubles.

Birds have lightweight beaks instead of jaws filled with heavy teeth, and some internal organs are reduced in size or absent.

Hydrocarbons are a non-renewable resource. They are non-renewable since they are fossil fuels such as coal, oil etc. Hydrocarbons are a primary energy source for current civilizations. The predominant use of hydrocarbons is as a combustible fuel source.

Calcium hydride was, in the 1940s, available under the trade name "Hydrolith" as a source of hydrogen:.

Ultraviolet rays are used to clean water in modern filters. Most ultraviolet purification systems are combined with various forms of filtration, as UV light is only capable of killing microorganisms such as bacteria, viruses, molds, algae and yeast. UV light generally has no impact on chlorine, VOCs and heavy metals.

Earthen pots have small pores through which the water seeps and as evaporation leads to cooling of the substance. Earthen pots are porous and thus contains air and air is a bad conductor of heat, and thus prevents heat transfer

Time for one oscillation is T = 2pi/12w = pi/6w,  so that the frequency = 1/T = 6w/pi Hz = number of oscillations each second.
