SPIDER WEB

   We can see a spider web in almost every place. These spider webs are cleaned and disposed of as waste but are many uses in them. Many searches are making research on a spider web and bio-mice. Spider weave the web mainly to catch their prey. Spider produce their silk from the spinneret gland located at the tip of their abdomen. Different spider produces different silk based on their presence of pair of the spinneret. Spider build the web to save their energy to catch the prey. Instead, they spend this energy offset in producing a large amount of protein(amino acid) to form the silk.

   After, the silk lost its stickiness spider eat the web to recoup some energy used in spinning. There are different webs namely spiral web, tangled web, funnel web, tubular web, sheet web. In traditional European medicine, cobweb is used on wound or cut and help to heal and reduce bleeding. Spider wed are rich in vitamin K which help to stop bleeding. The effect of the drug can be measured by examining its effect on the spider.

   The stickiness of the spider is due to a droplet of glue suspended on the silk thread. This glue contains neurotoxins which make the prey immoveable. At high velocity the glue act as an elastic solid, resembling rubber; at low-velocity act as sticky glue. This allows them to attach food particle. The web is electrically conductive which made the silk attract the insects .ie .the flying insect tend to gain the static charges. The tensile and elasticity of the web is higher than the steel.

WHY ATLANTIC AND PACIFIC OCEAN ARE NOT MIXED?

Nearly 72% of the earth is filled with water and it is present with different names- oceans, seas, rivers. Why are they named differently? There are five oceans namely Artic ocean, Atlantic Ocean, Pacific Ocean, Indian ocean and Antarctic ocean . All the oceans are different in their physical and biological character called ocean clines. When we look at the Atlantic and Pacific Ocean junction, they do not mix. Is there any invisible Wall in between them? Many scientists have conducted research to solve this mystery. The Atlantic and Pacific Ocean have different chemical composition. The salinity of the water in the Atlantic Ocean is five times more than the Pacific Ocean. The density of water is also different, so even marine animals in Atlantic Ocean will not go to the Pacific Ocean. They cannot survive in other oceans. Atlantic and Pacific Ocean meet at Cape Horn. The narrow straight line formed by the water bodies is called Drake Strait. The Pacific Ocean is ...

The Chemical Lake

 Spotted Lake or Lake khiluk in Canada is richly concentrated with various minerals. It contains dense deposits of magnesium sulfate, calcium, and sodium sulfates. It also contains high concentrations of eight other minerals and lower amounts of silver and titanium. Most of the water in the lake evaporates over the summer, revealing colorful mineral deposits. Large ‘spots’ on the lake appear and are colored according to the mineral composition and seasonal amount of precipitation. Magnesium sulfate, which crystallizes in the summer, is a major contributor to spot color.  Originally known to the First Nations of the Okanagan Valley (Native American Tribe) as Khiluk, Spotted Lake was for centuries and remains revered as a sacred site thought to provide therapeutic waters. It is the most mineralized lake in the world. Each spot holds a different cure due to the unique chemical content found within each puddle. Lake Khiluk is considered a saline endorheic alkali lake. The Okanag...

Why is the Pacific Ocean shrinking and the Atlantic Ocean is getting wider?

Twenty million years ago there was no Atlantic Ocean. But then, thanks to plate tectonics, the South American and North American continents were separated by a rift valley that eventually turned into the Atlantic Ocean. The complementary shapes of the South American and African continents have long been noticed, but it wasn't until the 1960s that the theory of plate tectonics became accepted as the explanation. These days, the Atlantic Ocean is growing at a rate of five centimetres per year, as new sea floor is created by volcanic activity along its mid-ocean ridge.        On the other hand, the much older Pacific Ocean is currently estimated to be shrinking by two to three centimetres each year. Again, this comes down to plate tectonics because the Pacific Ocean has subduction zones on three sides - where the Pacific plate submerges beneath other plates.  Since there are very few subduction zones in the Atlantic, Indian and Arctic oceans...
