Question: When people say that the genome of a sexually reproducing species has been "sequenced", typically they are referring to a determination of the sequences of one set of autosomes and one of each type of sex chromosome, which together represent both of the possible sexes. Even in species that exist in only one sex, what is described as a "genome sequence" may be a composite read from the chromosomes of various individuals. Colloquially, the phrase "genetic makeup" is sometimes used to signify the genome of a particular individual or organism.[citation needed] The study of the global properties of genomes of related organisms is usually referred to as genomics, which distinguishes it from genetics which generally studies the properties of single genes or groups of genes.
Try to answer this question if possible: What is the science that deals with the common genetic characteristics of related organisms called?
Answer: genomics
Question: After the creation of the Commonwealth of Australia in 1901, Norfolk Island was placed under the authority of the new Commonwealth government to be administered as an external territory. During World War II, the island became a key airbase and refuelling depot between Australia and New Zealand, and New Zealand and the Solomon Islands. The airstrip was constructed by Australian, New Zealand and United States servicemen during 1942. Since Norfolk Island fell within New Zealand's area of responsibility it was garrisoned by a New Zealand Army unit known as N Force at a large Army camp which had the capacity to house a 1,500 strong force. N Force relieved a company of the Second Australian Imperial Force. The island proved too remote to come under attack during the war and N Force left the island in February 1944.
Try to answer this question if possible: During what major event did Norfolk Island become an important airbase and refuelling station?
Answer: World War II
Question: Genetic engineering is now a routine research tool with model organisms. For example, genes are easily added to bacteria and lineages of knockout mice with a specific gene's function disrupted are used to investigate that gene's function. Many organisms have been genetically modified for applications in agriculture, industrial biotechnology, and medicine.
Try to answer this question if possible: What is another for which organisms have been modified for?
Answer: industrial biotechnology
Question: Many ground crew at the airport work at the aircraft. A tow tractor pulls the aircraft to one of the airbridges, The ground power unit is plugged in. It keeps the electricity running in the plane when it stands at the terminal. The engines are not working, therefore they do not generate the electricity, as they do in flight. The passengers disembark using the airbridge. Mobile stairs can give the ground crew more access to the aircraft's cabin. There is a cleaning service to clean the aircraft after the aircraft lands. Flight catering provides the food and drinks on flights. A toilet waste truck removes the human waste from the tank which holds the waste from the toilets in the aircraft. A water truck fills the water tanks of the aircraft. A fuel transfer vehicle transfers aviation fuel from fuel tanks underground, to the aircraft tanks. A tractor and its dollies bring in luggage from the terminal to the aircraft. They also carry luggage to the terminal if the aircraft has landed, and is being unloaded. Hi-loaders lift the heavy luggage containers to the gate of the cargo hold. The ground crew push the luggage containers into the hold. If it has landed, they rise, the ground crew push the luggage container on the hi-loader, which carries it down. The luggage container is then pushed on one of the tractors dollies. The conveyor, which is a conveyor belt on a truck, brings in the awkwardly shaped, or late luggage. The airbridge is used again by the new passengers to embark the aircraft. The tow tractor pushes the aircraft away from the terminal to a taxi area. The aircraft should be off of the airport and in the air in 90 minutes. The airport charges the airline for the time the aircraft spends at the airport.
Try to answer this question if possible: How long should it take for an aircraft to be off the airport and in the air?
Answer:
90 minutes
