Greece has the largest merchant navy in the world, accounting for more than 15% of the world's total deadweight tonnage (dwt) according to the United Nations Conference on Trade and Development. The Greek merchant navy's total dwt of nearly 245 million is comparable only to Japan's, which is ranked second with almost 224 million. Additionally, Greece represents 39.52% of all of the European Union's dwt. However, today's fleet roster is smaller than an all-time high of 5,000 ships in the late 1970s.

Eventually, when it was more common for electric recordings to be played back electrically in the 1930s and 1940s, the overall tone was much like listening to a radio of the era. Magnetic pickups became more common and were better designed as time went on, making it possible to improve the damping of spurious resonances. Crystal pickups were also introduced as lower cost alternatives. The dynamic or moving coil microphone was introduced around 1930 and the velocity or ribbon microphone in 1932. Both of these high quality microphones became widespread in motion picture, radio, recording, and public address applications.

In what years would you find electronic recordings played electronically?
Answer: 1930s and 1940s

Historically, in North America, one of the most economically destructive pests in cotton production has been the boll weevil. Due to the US Department of Agriculture's highly successful Boll Weevil Eradication Program (BWEP), this pest has been eliminated from cotton in most of the United States. This program, along with the introduction of genetically engineered Bt cotton (which contains a bacterial gene that codes for a plant-produced protein that is toxic to a number of pests such as cotton bollworm and pink bollworm), has allowed a reduction in the use of synthetic insecticides.

What form of cotton contains a genetically modified gene?
Answer:
Bt cotton
