    Breathing Is Not a Continuous Process But Respiration Is a Continuous Process 2.Breathing Is Physical And Respiration Is Chemical Process 3.Breathing Take Place in the Respiratory Organs Like Lungs While Respiration Occurs In Cell 4. Breathing Is Volantary Process While Respiration Is InVolantary 5.Breathing is the process of getting oxygen into the lungs and carbon dioxide out of the lungs. It allows for gas exchange to take place so that oxygen can be absorbed from the lungs into the blood and carbon dioxide is removed from the blood and breathed out from the lungs. While Respiration is the release of energy from the break down of glucose in living cells. Respiration takes place in every living cell and all cells need to respire to produce the energy they need. 6. Breathing Is Not Further Divided Into Further Parts While Respiration Has Two Types Aerobic And Anaerobic

    An atom is the smallest constituent unit of ordinary matter that constitutes a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small; typical sizes are around 100 picometers (1×10−10 m, a ten-millionth of a millimeter, or 1/254,000,000 of an inch).

    The main agents of mechanical weathering are water, wind, ice, and gravity. You will see how each of these works to break rock into smaller pieces. There are two main ways that rocks can break apart into smaller pieces. The way that is most common in cold climates is called ice wedging.

    Galvanization is the process to protect iron from rust.

    1Thank You

    Yogita Ingle 6 years, 3 months ago

    Galvanization is the process by which zinc is coated over corrosive (easily rusted) metals. Galvanizing involves coating corrosive metals, such as steel and iron, with a non-corrosive metal. The process of galvanizing, not only protects from corrosion of various ‘soft metals’ but also adds strength of the original, uncoated metal. Apparently, galvanized metal is thicker than the uncoated metal and so fittings and fastenings are generally measured with the additional galvanizing layer height specs in mind. American Society for Testing and Materials (ASTM) specifications provide guidelines for the thickness of galvanized metals based on the underlying metal and the type of application. Galvanization refers to any of several electrochemical (branch of chemistry that studies chemical reaction which take place in a solution) processes named after the Italian scientist Luigi Galvani. Now the term generally refers to an electro deposition (electroplating) process used to add a thin layer of another metal to a ferrous substrate, in order to prevent rusting.

    1. A clinical thermometer is a thermometer which is used to measure the temperature of a human body. 2.Its range is from 35°c to 42°c. 3.A clinical thermometer has a kink inside it, which stops mercury level from rising or falling on its own. 4.It has a mercury inside the tube. 5.A clinical thermometer should be washed before and after use with anticeptic solution. 6.It should not be handle with bulb. 7.It should be handled carefully, othervise it would break. 8.A clinical thermometer has two scales inside it. i. Celsius scale - 35°c to 42°c. ii. Fahrenheit scale - 94°c to108°c. 9. mercury is hard to dipose, so nowadays digital thermometer are available. 10. Clinical thermometer should not come in contact with heat or flame near it, otherwise it may burn and get damaged or become exploded. 11. Mercury is a type of liquid metal which couldn't be got dispose. 12. Clinical thermometer shouldn't be used for testing an object. 13. Normal human temperature of human beings in celsius scale and Fahrenheit scale are as follows: i. 37°c. ii. 98.4°c. Hope you will be able to get good marks in the exam.

Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,276 species described.[4] Vertebrates include such groups as the following: jawless fishes jawed vertebrates, which include the cartilaginous fishes (sharks, rays, and ratfish) tetrapods, which include amphibians, reptiles, birds and mammals bony fishes -----------------------------------------+------------------------------------ Invertebrate is a kind of animal that does not have a spinal column or backbone. It is the opposite of vertebrate, that means if an animal is not a vertebrate (fish, reptile, amphibian, bird, or mammal), it is an invertebrate. The main phyla (groups) of invertebrate animals are: Annelida: segmented worms Arthropods: (arachnids, crustaceans, insects, and others); Brachiopods: the lamp-shells. Bryozoa: sea mats or moss animals (sometimes they look like corals) Cnidarians: jellyfish, sea anemones, hydroids. Echinoderms: starfish, sea urchins, sea cucumbers Molluscs: (gastropods, cephalopods, bivalves and others); Nematoda: roundworms Porifera: sponges Platyhelminthes: flatworms Rotifers: tiny "wheel animals", which live in habitats such as pond water. Insects and other arthropods have no bones, but they have a skeleton on the outside of their bodies, called an exoskeleton.

    Charles's law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated. A modern statement of Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion.[1] This relationship of direct proportion can be written as: {\displaystyle V\propto T}{\displaystyle V\propto T} So this means: {\displaystyle {\frac {V}{T}}=k,\quad or\quad V=kT}{\displaystyle {\frac {V}{T}}=k,\quad or\quad V=kT} where: V is the volume of the gas, T is the temperature of the gas (measured in kelvins), and k is a non-zero constant. This law describes how a gas expands as the temperature increases; conversely, a decrease in temperature will lead to a decrease in volume. For comparing the same substance under two different sets of conditions, the law can be written as: {\displaystyle {\frac {V_{1}}{T_{1}}}={\frac {V_{2}}{T_{2}}}\qquad {\text{or}}\qquad {\frac {V_{2}}{V_{1}}}={\frac {T_{2}}{T_{1}}}\qquad {\text{or}}\qquad V_{1}T_{2}=V_{2}T_{1}.}{\displaystyle {\frac {V_{1}}{T_{1}}}={\frac {V_{2}}{T_{2}}}\qquad {\text{or}}\qquad {\frac {V_{2}}{V_{1}}}={\frac {T_{2}}{T_{1}}}\qquad {\text{or}}\qquad V_{1}T_{2}=V_{2}T_{1}.} The equation shows that, as absolute temperature increases, the volume of the gas also increases in proportion.

    During the early years, nylon was always considered a smoother and softer fabric than polyester. Nylon was created as a substitute for silk and it shows in its soft, lustrous feel. From its inception, polyester has always been a rougher fabric than nylon, hence its original use in outerwear garment and suits. The refined manufacturing capabilities of today have resulted in softer polyester that in many ways matches nylon and certainly the softness of cotton.
