Why whale vomit is too expensive ? - AMBERGRIS The Floating Gold

Image
The Whale vomit !!!! . Why it is too expensive ? I'll tell you.  Whale vomit  is  also called as " ambergris " " treasure of the sea " and " floating gold   ". Ambergris is a waxy and solid substance formed due to the secretion of bile duct in the intestine of sperm whale . It floats in water. When exposed to the sunlight, air and sea water it hardens, fades to a light grey and yellow in colour. Eventually develops fragrance. And now it has been highly valued by perfume makers as a fixative . These whales are not normally harmed during the collection of ambergris, The sale of this product is also illegal because it is produced from an endangered species .

BLOG AND TOPICS

Image
When it comes to writing a blog I will always makes sure that everyone who reads the contents in my blog should get a brief idea about what is happening all over the world. Modern technologies, scientifical experiments  are always there in my top list in mind. A person, it may be me or you when starts writing, it should not stop before giving all the possible ideas to our audience.  When i was a science student all of the topics related to our syllabus gave me a small idea to what is it ? and why is that ? A person who does not belong to science stream should know about them. The Genetics, Molecular science, Physics, Chemistry, whatever the topic is always should be learned. Before writing about a topic i had been googled and tried to gather every information as possible. Most of the people around us now days are lazy. Wasting their valuable time on digital gadgets by playing games and scrolling for nothing . Now they can get these Newses through the same gadgets. Anyone can r...

NOCTILUCA SCINTILLANS - SEA SPARKLE

Image
Noctiluca scintillans is a marine dinoflagellate that is responsible for bioluminescence in coastal regions of the world. They are bouyant and balloon shaped single cell. It has an oral pouch, a short flagellum and tentacle. The scintillating effect of Noctiluca’s bioluminescence, which is most conspicuous at night during a bloom  this phenomenon is called “burning of the sea” or “sea sparkle” . Noctiluca reproduce through binary fission (separation of the cell into two bodies) or multiple fission (separation of the cell into more than two bodies). The latter, which involves the cell-division processes of meiosis and mitosis , results in the production of numerous motile swarmers that bud off from the parent cell.  

LIQUID NITROGEN

Liquid nitrogen is a form of element nitrogen that's cold enough to exist in a liquid state and can be used to many cooling and  cryogenic purposes. Because of the  severe problems on contact with living tissue, you must wear proper safety gear when handling liquid nitrogen to prevent contact or inhalation of the extremely cold vapour. Cover and insulate skin to avoid exposure.  It boils so rapidly, so that the phase transition from liquid to gas can generate a lot of pressure very quickly. Do not enclose liquid nitrogen in a sealed container, as this may result in it bursting or an explosion.  Adding large quantities of nitrogen to the air reduces the relative amount of oxygen, which may result in an asphyxiation risk. Cold nitrogen gas is heavier than air, so the risk is greatest near the ground. Use liquid nitrogen in a well-ventilated area.  Liquid nitrogen containers may accumulate oxygen that is condensed from the air. As the nitrogen evaporates, there's...

TOTIPOTENCY

Image
Ever wondered how an entire plant is produced under laboratory conditions in a test tube from any of its parts ? Don't think too much . Here is the answer. Because each and every cell in plant are totipotent. That means any single cell is capable of giving rise to any cell type. More precisely totipotency is the ability of a plant to grow an entire plant from an individual cell. It makes the plant s different from animals. This is the main principle behind tissue culture .  All the plants can undergo cellular differentiation if we provide appropriate conditions for them in a laboratory. In animals zygote is the only cell that can undergo differentiation and capable of developing into all the specialized cells that make up the adult animal.
