Our  skin  is  a protective  layer  between   the body  and its  external environment.It  works  as   a  sensor to mo niter  changes  in exterior  physical   conditions.Different  kinds  of  situations such  as heat,cold,pain and pressure,provoke different types   of nerve  cells,in the skin.Thus  ,the  brain   is  sent  the  useful information of the happenings,outside the body,and  it in turn, commands   an action& nbsp; to different   parts  of the body.For example,when  we happen to  hold a flower  with  a thorn and detect  pain,message  from   the arm  are sent  to  the spine.A spine  sends  this message  to  the brain    and  brain  command  the hand muscles   to throw  the flower.All  this  happens  in less than  one   second.Thus  , these  nerve cells prevent  our body  from  damage or injury.Our  skin  feels  the pressure and the pain,so  we feel  when  our finger is cut  by knife.There  are millions  of microscopic   nerve endings  under  the  surfac

A human nose  can distinguish around  4000 different  substances.We  use our nose  to breathe  and to smell.We can differentiate  the god and bad odor.Smell  floats in the air.We smell  things  we take in air  through  our noses.The sensory cells  in the nose,detect the smell and send message to the brain.Our sense  of smell  also  help  our sense of taste.So, our sense of smell and taste are  closely linked. Our tongue  receptors   differentiate  only four  types of taste qualities; sweet,sour,salt,and bitter.There  are thousands  of taste  buds all over  the tongue.These   survive  only for a matter of days  under go  rapid and continuous   replacement.Each  taste  bud  consist  of  sensory  cells  that  are  connected    to  the mid brain through taste  fibers.The  sensors  send  massage  to  the  brain about what we  are  eating.The  front  of the tongue  taste  sweet things,the sides of the tongue  taste  salty  and sour things.The back  of the tongue  tast

'Big data' is the new science of understanding and predicting human behavior by studying large volumes of unstructured data.  Big data is also known as 'predictive analytics'. '.Analyzing Twitter posts, Facebook feeds, eBay searches, GPS trackers, and ATM machines are some big data examples. Studying security videos, traffic data, weather patterns, flight arrivals, cell phone tower logs, and heart rate trackers are other forms. Big data is a messy new science that changes weekly, and only a few experts understand it all.    Most big data projects are very obscure, there are successful exa mples of big data affecting the everyday life of individuals, companies, and governments: Predicting virus outbreaks: by studying socio-political data, weather and climate data, and hospital/clinical data, these scientists are now predicting dengue fever outbreaks with 4 weeks advance notice.

The white shark, commonly called the great white shark, is one of the most iconic and feared creatures of the ocean. With its razor-sharp teeth and menacing appearance, it certainly looks dangerous. But the more we learn about this creature, the more we learn they are not indiscriminate predators, and definitely don't prefer humans as prey. Great white sharks are relatively large, although likely not as large as they might be in our imagination.   T he largest shark species is a plankton eater, the whale shark. Great whites average about 10-15 feet in length, and their maximum size is estimated at a length of 20 feet and weight of 4,200 pounds. Females are generally larger than males. They have a stout body, black eye, a steel gray back and a white underside.  Great white sharks are widely distributed across the world's oceans. This shark resides mostly in temperate waters in the pelagic zone. They can range to depths over 775 feet. They may patrol coast

You already know that a good workout can burn calories. And you might even boost your step count during the day to burn calories and slim down. But did you know that you can choose certain foods to burn calories?  Everything that you do during the day burns calories, including eating. But eating some foods can burn more calories than others. And the best calorie-burning foods provide other nutritional and weight-loss benefits as well. How Food Burns Calories When you eat food, you consume calories or energy.  But you also need energy to carry out the eating process. Chewing, digesting and storing food require your body to burn calories. Scientists call it the thermic effect of food or TEF.  Your TEF is a primary component of your total daily energy expenditure or TDEE.  That's the total number of calories that you burn throughout the day.  So how much more can you burn with the best calorie-burning foods? Unfortunately, not many. The calories you bu

The  Spine  or vertebral,column has  two  main  functions;it serve  as a  protective  surrounding  for  the delicate  spinal  cord. and form the  supporting   back  bone of the Skeleton .The spine consist  of 24   separate   differently  shaped  bones vertebrae  with  a curved  ,triangular  bone the sacrum at the  bottom.The  sacrum  is made up  of  fused  vertebrae  ; at  the  lower  end   is  a  small  tail  like  structure  made up  of tiny  bones ,collectively  called  the coccyx.Between  each pair  of vertebrae  is a disk  of cartilage  that cushions  the  bones during the movement.The  top  two  vertebrae differ  in  appearance  from  the others  and works  as a pair ;the  first  called  the atlas ,rotates   around  a stout vertical  peg  on  the second,the axis.This arrangement  allows  the skull  to  move freely up  and down, and from side to side.

WITH   EVERY  BREATH   ,air  passes  through  the  nasal   cavity..down   the   pharynx(throat),larynx("voice box"  ),and  trachea(wind pipe)  to  the  lungs.The  nasal   cavity   warms  the  and  moistens  air   ,and   the  tiny  layers  in  the  lining   protect   the  airway    against   the  damage  by  foreign  bodies.During  swallowing  ,  the  tongue  moves  up  and  back,the  larynx  rise,the  epiglottis  closes  off  the    entrance to  the trachea,  and  the  soft palate  separates    the  nasal  cavity  from  the  pharynx.Saliva, secreted  from   three  pairs  of    salivary   glands,lubricates  food  to  make  swallowing   easier,it  also   begin  the   chemical  break down  of   food ,and  help  to  produce  taste.The  senses  of  taste   an d   smell     are  closely  linked .Both  depend  on   the    detection of   dissolved    molecules  by   sensory  receptors  in  the  olfactory nerve endings  of  the  nose  and  in  the   taste  buds  of 

In  a  new  born   baby,the  head accounts   for  one-quarter  of the total   body length ;by  adulthood  , the proportion  has reduced   to  one-eighth.The  contained  the  body's   main   sense  organs.:Eyes,ears,olfactory  nerves,  that  detect  smells,and  the  taste  buds  of the  tongue .Signals    from  from  these  organs  pass in  the  body's  great   coordination  centre ;the  brain .housed  in  the protective, bony  dome  of  the skull.Hair  on  the  head insulates against   heat  loss,and adult  males  also  grow  thick facial  hair.The  face  has three   important  openings.two  nostrils  through   which  air  passes,and  the  mouth.Which  takes  in  nourishment  and  form  speech.Although  all  heads  are  basically  similar, differences   in  size,shape,and  colour  produce  an   infinite  variety  of   appearances.

Our genes determine our physical characteristics such as height, weight, and skin color. These genes sometimes experience mutations that alter the physical traits observed. Gene mutations are changes that occur in the segments of DNA that compose a gene. These changes can be inherited from our parents through sexual reproduction or acquired throughout our lifetime. While some mutations can lead to diseases or death, others may have no negative impact on or may even benefit an individual.  Other mutations can produce traits that are  cute.  Some  cute features caused by gene mutations. Dimples.   Dimples are a genetic trait that causes the skin and muscles to form indentations in the cheeks. Dimples can occur in either one or both cheeks. Dimples are typically an inherited trait passed down from parents to their children. The mutated genes that cause dimples are found within the sex cells of each parent and are inherited by the offspring when these
