Answer #1

The N15 isotope of N14 is heavier than the normal 1. 99.9% is N14 only on earth. Whereas some part also consist of N15 which is also a stable isotope. marine organisms use N15 for their metabolism and the nitrogen cycle taking place is also able to enrich N15 again in the oceans. Being present at high pressure. It is formed from the radioactivities and interactions of Carbon -15 and Oxygen-15 isotopes present in the deep oceans. Thus, it is found more in the marine.

On terrestrial world , the organisms utilize only N14 as it is present in atmosphere in most abundant forms , which is taken up by organisms.

Many terrestrial digital TV broadcasting systems are based on the DVB-T standard, implemented using a Single Frequency Network, in which the same channel can broadcast on the same frequency in different locations, even when there is overlapping coverage. OFDM modulation is used, commonly with several thousand subcarriers within each 6-8 MHz bandwidth channel. Error correcting codes are applied to the digital bitstreams representing the TV video, audio and data streams, and they typically contribute a 10-20% increase in bit rate....
