Here is a question about this article: The isolation of enzymes from infected tissue can also provide the basis of a biochemical diagnosis of an infectious disease. For example, humans can make neither RNA replicases nor reverse transcriptase, and the presence of these enzymes are characteristic of specific types of viral infections. The ability of the viral protein hemagglutinin to bind red blood cells together into a detectable matrix may also be characterized as a biochemical test for viral infection, although strictly speaking hemagglutinin is not an enzyme and has no metabolic function.
What is the answer to this question: What enzyme's presence is characteristic of specific types of viral infections?
****
So... RNA replicases


The problem: Answer a question about this article:
NATO defines anti-aircraft warfare (AAW) as "measures taken to defend a maritime force against attacks by airborne weapons launched from aircraft, ships, submarines and land-based sites." In some armies the term All-Arms Air Defence (AAAD) is used for air defence by non-specialist troops. Other terms from the late 20th century include GBAD (Ground Based AD) with related terms SHORAD (Short Range AD) and MANPADS ("Man Portable AD Systems": typically shoulder-launched missiles). Anti-aircraft missiles are variously called surface-to-air missile, abbreviated and pronounced "SAM" and Surface to Air Guided Weapon (SAGW).
What does SHORAD stand for?
****
The answer: Short Range AD


Problem: Please answer a question about the following article about Insect:
The life cycles of insects vary but most hatch from eggs. Insect growth is constrained by the inelastic exoskeleton and development involves a series of molts. The immature stages can differ from the adults in structure, habit and habitat, and can include a passive pupal stage in those groups that undergo 4-stage metamorphosis (see holometabolism). Insects that undergo 3-stage metamorphosis lack a pupal stage and adults develop through a series of nymphal stages. The higher level relationship of the Hexapoda is unclear. Fossilized insects of enormous size have been found from the Paleozoic Era, including giant dragonflies with wingspans of 55 to 70 cm (22–28 in). The most diverse insect groups appear to have coevolved with flowering plants.
An insects developement involves a series of what?
A: molts

Although this period had been productive, the bad weather had such a detrimental effect on Chopin's health that Sand determined to leave the island. To avoid further customs duties, Sand sold the piano to a local French couple, the Canuts.[n 8] The group traveled first to Barcelona, then to Marseilles, where they stayed for a few months while Chopin convalesced. In May 1839 they headed for the summer to Sand's estate at Nohant, where they spent most summers until 1846. In autumn they returned to Paris, where Chopin's apartment at 5 rue Tronchet was close to Sand's rented accommodation at the rue Pigalle. He frequently visited Sand in the evenings, but both retained some independence. In 1842 he and Sand moved to the Square d'Orléans, living in adjacent buildings.

What is stated as having a negative effect on Frédéric's health during this productive time?
Answer: bad weather


Problem: The term Appalachian refers to several different regions associated with the mountain range. Most broadly, it refers to the entire mountain range with its surrounding hills and the dissected plateau region. The term is often used more restrictively to refer to regions in the central and southern Appalachian Mountains, usually including areas in the states of Kentucky, Tennessee, Virginia, Maryland, West Virginia, and North Carolina, as well as sometimes extending as far south as northern Alabama, Georgia and western South Carolina, and as far north as Pennsylvania, southern Ohio and parts of southern upstate New York.
What does the term Appalachian refer to?
The answer is the following: several different regions associated with the mountain range


Input: Article: In mid-November The Shevchenko Ukrainian Language Society was officially registered.
