direct sequence spread spectrum (DSSS) or direct sequence code division multiple access (DS-CDMA) Direct sequence spread spectrum, also known as direct sequence code division multiple access (DS-CDMA), is one of two approaches to spread spectrum modulation for digital signal transmission over the airwaves.
Best Answer: There has not been a turtle followed from emergence to natural death, so this is a guesstimate based on the information we do have. It is assumed that sea turtles can live 60 or more years depending on species. Onset of sexual maturity is also species dependant, but is typically around 20 years. well it depends if the sea turtle is healthy or not or if it's in the right habitat. it also depends on what kind of sea turtle as well.
Sea Turtle History. The oldest fossils of turtles were found in Germany and date back 215 million years, during the Triassic period. 1 They are among the oldest fossils of four-legged animals and one of the Earthâs most ancient creatures.These ancestral turtles had completely formed shells and lived on land, in marshes.here are two groups of sea turtles: Dermochelyidae, including the Leatherback, are the most ancient sea turtles, the largest, and the only sea turtles without a hard shell; Cheloniidae, including the other six types of sea turtle, vary in size but all have a hard shell.
