Sea Turtle


 Emerging from  marsh inhabiting ancestors 144 to  208 millions years ago, before flowering plants grew on earth, modern scientists believe sea turtle left the land their  reptilian ancestors had settled upon, and returned to the ocean. Their streamlined body shape and powerful limbs make them excellent swimmers. Their fore flippers beat with wing - like motion, propelling them  forward, while their back limbs stabilise and direct their movement. 

They spend their entire lives swimming  the waters of the world. Of the eight species of sea turtles, only the Hawaiian green sea turtle is known to typically rest on shore, basking in the sun's warmth. Otherwise, only mothers come ashore, for about 2 hours, to dig a nest in the sand, generally the size of her body, at a safe distance from an average tide. She leaves the ocean under cover of dark and lays between 50 and  200 eggs roughly the size of balls in the nest during the night. Covering the eggs with the dug out sand to protect them, she crawls her way back to the ocean.

More the number of soldiers increases the cost becomes high. There are countries in the world that do not have armed forces for security, only the police give their service instead such as Marshall Islands, Palau, Saint Lucia, Samoa, Andorra, Vatican City. If these countries can survive without an arme...

Water

    What are the rarest things of the universe? one of those thing is definitely water. Researches suggest that water is only found on earth. And this is the reason that our planet supports life. The earth is full of an abundance of water. About 70% of the surface of the earth is covered with water. But a very little part of the whole is actually is attainable and useful for us. Humans use it carelessly like it has no value at all. Water is precious resource that nature has given to man. Water is also important for all flora and for all life forms. Terrestrial life form require water to drink. If they do not get water to drink they will perish. All aquatic organisms need water bodies to live. Water bodies, whether they are rivers or oceans ,are their habitat. Vegetation requires water to survive. Water  is there for an important resources that must be saved. We should not waste water.

A famous person I admire

Image
   As a music student there is a special character that I admire most. He was a giant in Western Music in the past. He is a great composer known as Wolfgang Amedeaus Mozart. Also known as "the prince of concertos". He was born in 1756 and he spent his youth in Salzburg court with his father. He had composed various types of music such as canons ,Waltz, concertos ,operas etc. He introduced melodic and harmonic structure, Alberti bass, ornaments to  Western Music. His compositions numbered as "K numbers". His death was very disappointing as his burial was in a beggar's grave. I appreciate his character because he was a very encouraged and interesting character. His dedication and commitment made him achieve his targets. I admire not only his qualities but also his amazing talent in the field of Western Music.
