There are 40 extant specie   Compared to other animals, dolphins are believed to be very intelligent. The Killer Whale (also known as Orca) is actually a type of dolphin. Bottlenose dolphins are the most common and well known type of dolphin. Female dolphins are called cows, males are called bulls and young dolphins are called calves. Dolphins are extraordinarily intelligent animals who also display culture, something which was long-believed to be unique to humans (although now recognized in various species). ... Dolphins are altruistic animals. They are known to stay and help injured individuals, even helping them to the surface to breath.   Dolphins are found all across the world and are close relatives of whales.

SOME BLOODY FACTS

      Blood is the life giving fluid that delivers oxygen to the cells of the body. It is a specialized type of connective tissue that consists of red blood cells, platelets, and white blood cells suspended in a liquid plasma matrix. Did you know that blood accounts for about 8 percent of your body weight or that blood contains small amounts of gold?  While humans have red colored blood, other organisms have blood of varying colors. Crustaceans, spiders, squid, octopuses, and some arthropods have blue blood. Some types of worms and leeches have green blood. Some species of marine worms have violet blood. Insects, including beetles and butterflies, have colorless or pale-yellowish blood. The color of blood is determined by the type of respiratory pigment used to transport oxygen via the circulatory system to cells. The respiratory pigment in humans is a protein called hemoglobin found in red blood cells. Your body contains about a g

ANTIBODIES =PROTECTOR OF BODY

  What Are Antibodies? Antibodies (also called immunoglobulins) are specialized proteins that travel thorough the blood stream and are found in bodily fluids. They are utilized by the immune system to identify and defend against foreign intruders to the body. These foreign intruders, or antigens, include any substance or organism that evokes an immune response. Bacteria, viruses, pollen, and incompatible blood cell types are examples of antigens that cause immune responses. Antibodies recognize specific antigens by identifying certain areas on the surface of the antigen known as antigenic determinants. Once the specific antigenic determinant is recognized, the antibody will bind to the determinant. The antigen is tagged as an intruder and labeled for destruction by other immune cells. Antibodies protect against substances prior to cell infection. Antibody Production Antibodies are produced by a type of wh

DIGESTIVE SYSTEM

  We   need food  to keep  us alive.What happens  to that food  inside our body? The process from  the moment  the food enter the mouth until  it mixes  into blood stream is called  digestion.Digestion  usually  takes up  to 18 hours.There are about  8 meters  of tubes and chambers inside our body that process  the food eaten by us.It consist of organs that  help in chewing ,swallowing,breakdown and absorption   of food as well as expulsion  from the body of what is left afer  the process.In  the mouth the  tongue and teeth  helps   in  breaking of food  .Then  this  bolus  is transferred  to the stomach after we swallow  it. Gastric juce in  the  stomach  ,is rich  in  hydrocloric  acid  and the protein-spilitting  enzyme  pepsin.Then  food reaches Duodenum through  a muscular   valve.The   pancreatic juce contains  enzymes for splitting  carbohydrate,protein and fat  in  the  food.Bile  a bitter liquid  in the liver  also   help  in this process.This  useful  digeste

Bacteria

  Bacteria   are   the   most   plentiful   living  organism   on  the  Earth.They   are  the  most  smallest    organism ,each  consisting   of  a   simple ,  single  cell.A   few   types  of  bacteria ,called  germs ,cause  diseases    in  humans .But   most  bacteria     are   harmless,  some  are   very  useful.They   used  in  making  drugs   and  foods. Bacteria    reproduce   by  binary   fission(splitting  in  two). Reproduction    by     division   means  that  bacteria  can   multiply  very  quickly,if  the  conditions   are  just   right.Bacteria   comes  in  three   shapes- Cocci,called  coccus    are  sp herical Bacilli, called  a  bacillus    are  rod  shaped. Spirilla,one  is  called  a  spirillum  are  spiral   shaped. First   bacteria   appear more  than   900  millions  years  after    Earth   formed.Dutch  scientist   Antoni  van  Leeuwenhoek   was  the  first  person    to  see  bacteria  ,  in  scrapping  of  his  teeth   in  1683.F

hoaxed/spoofed email

    A hoaxed/spoofed email is when the sender purposely alters parts of the email to masquerade as though it was authored by someone else. Commonly, the sender’s name/address and the body of the message are formatted to appear from a legitimate source, as though the email came from a bank or a newspaper or legitimate company on the Web. Sometimes, the spoofer will make the email appear to come from a private citizen somewhere. In more benign cases of email hoaxes, these spoofed messages are used to spread urban myths and preposterous stories (e.g. Mel Gibson was horrifically burned as a teenager). In other more malevolent cases, the spoofed email is part of a phishing (con man) attack. In other cases, a spoofed email is used to dishonestly market an online service or sell you a bogus product like scareware. Why Would Someone Fraudulently 'Spoof' an Email? Purpose 1: the email spoofer is trying to “phish” your passwords and login names. Ph
