Ans: testing of a new system of navigation signaling and inter-satellite links

Article: A large percentage of herbivores have mutualistic gut flora that help them digest plant matter, which is more difficult to digest than animal prey. This gut flora is made up of cellulose-digesting protozoans or bacteria living in the herbivores' intestines. Coral reefs are the result of mutualisms between coral organisms and various types of algae that live inside them. Most land plants and land ecosystems rely on mutualisms between the plants, which fix carbon from the air, and mycorrhyzal fungi, which help in extracting water and minerals from the ground.

Question: What type of relationship do herbivores have with the bacteria in their intestines?
Ans: mutualistic

Article: Whereas the chromosomes of prokaryotes are relatively gene-dense, those of eukaryotes often contain regions of DNA that serve no obvious function. Simple single-celled eukaryotes have relatively small amounts of such DNA, whereas the genomes of complex multicellular organisms, including humans, contain an absolute majority of DNA without an identified function. This DNA has often been referred to as "junk DNA". However, more recent analyses suggest that, although protein-coding DNA makes up barely 2% of the human genome, about 80% of the bases in the genome may be expressed, so the term "junk DNA" may be a misnomer.

Question: What type of organism has relatively gene dense chromosomes?
Ans: prokaryotes

Article: However, the 18th century saw the European empires gradually expand across the world, as European states developed economies built on maritime trade. The dynasty was confronted with newly developing concepts of the international system and state to state relations. European trading posts expanded into territorial control in nearby India and on the islands that are now Indonesia. The Qing response, successful for a time, was in 1756 to establish the Canton System, which restricted maritime trade to that city and gave monopoly trading rights to private Chinese merchants. The British East India Company and the Dutch East India Company had long before been granted similar monopoly rights by their governments.

Question: Which two European companies traded in Canton?
Ans:
British East India Company and the Dutch East India Company
