Here is a question about this article: In addition to the use of sound for communication, a wide range of insects have evolved chemical means for communication. These chemicals, termed semiochemicals, are often derived from plant metabolites include those meant to attract, repel and provide other kinds of information. Pheromones, a type of semiochemical, are used for attracting mates of the opposite sex, for aggregating conspecific individuals of both sexes, for deterring other individuals from approaching, to mark a trail, and to trigger aggression in nearby individuals. Allomonea benefit their producer by the effect they have upon the receiver. Kairomones benefit their receiver instead of their producer. Synomones benefit the producer and the receiver. While some chemicals are targeted at individuals of the same species, others are used for communication across species.

Here is a question about this article: The end for the Laemmles came with a lavish version of Show Boat (1936), a remake of its earlier 1929 part-talkie production, and produced as a high-quality, big-budget film rather than as a B-picture. The new film featured several stars from the Broadway stage version, which began production in late 1935, and unlike the 1929 film was based on the Broadway musical rather than the novel. Carl, Jr.'s spending habits alarmed company stockholders. They would not allow production to start on Show Boat unless the Laemmles obtained a loan. Universal was forced to seek a $750,000 production loan from the Standard Capital Corporation, pledging the Laemmle family's controlling interest in Universal as collateral. It was the first time Universal had borrowed money for a production in its 26-year history. The production went $300,000 over budget; Standard called in the loan, cash-strapped Universal could not pay, Standard foreclosed and seized control of the studio on April 2, 1936.
What is the answer to this question: In what year had Universal previously made a version of Show Boat?
****
So...
1929
