Elephants live in parts of Africa and Asia. They eat only plants, including grasses, leaves, and fruit that they collect with the trunk. They live in small family groups, or herds, led by adult females.
DNA in the cell nucleus carries a genetic code, which consists of sequences of adenine (A), thymine (T), guanine (G), and cytosine (C) (Figure 1). RNA, which contains uracil (U) instead of thymine, carries the code to protein-making sites in the cell. To make RNA, DNA pairs its bases with those of the “free” nucleotides (Figure 2). Messenger RNA (mRNA) then travels to the ribosomes in the cell cytoplasm, where protein synthesis occurs (Figure 3). The base triplets of transfer RNA (tRNA) pair with those of mRNA and at the same time deposit their amino acids on the growing protein chain. Finally, the synthesized protein is released to perform its task in the cell or elsewhere in the body.
Iguassu Falls, “an ocean plunging into an abyss” on the border between Argentina and Brazil. The waterfall system consists of 275 falls along 2.7 kilometers (1.67 miles) of the Iguassu River. Position is at latitude (DMS): 25° 40' 60 S, longitude (DMS): 54° 25' 60 W . Some of the individual falls are up to 82 meters (269 ft) in height, though the majority are about 64 metres (210 ft). The Garganta del Diablo (Devil's Throat; Garganta do Diabo in Portuguese), a U-shaped 82-meter-high, 150-meter-wide and 700-meter-long (490 by 2300 feet) cliff, is the most impressive of all, and marks the border between Argentina and Brazil. Two thirds of the falls are within Argentine territory. [1] About 900 metres of the 2.7-kilometer length does not have water flowing over it. The edge of the basalt cap recedes only 3 mm per year. The water of the lower Iguassu collects in a canyon that drains into the Parana River in Argentina, shortly downstream from the Itaipu dam.
Angkor Wat (Cambodia) is not only the largest Hindu Temple, but also one of the wonders of the word. Yet, unknown to many Hindus all around! An architectural marvel and a piece of world heritage. Indians know more about Taj Mahal and almost nothing about this temple at Angkor Wat. Religion apart, this beautiful temple and it's intricate architectural wonder that signifies a symbol of Science and Mathematics in ancient times. There might not have been any Civil Engineering at that time, but even today the Engineers of Modern days, will have to bet their heads to recreate something like this. Likewise, there are many wonders which people do not know about. We are lost in Eiffel Tower and things like Egyptian Pyramids, but there are lot more of Indian marvels and structures, in other places - why, even in China, Japan & Singapore also! Angkor Wat (or Angkor Vat) is a temple at Angkor, Cambodia, built for king Suryavarman II in the early 12Th century as his state temple and capital...
