Problem: Eastern or Canada hemlock (Tsuga canadensis) is another important evergreen needle-leaf conifer that grows along the Appalachian chain from north to south, but is confined to lower elevations than red spruce and the firs. It generally occupies richer and less acidic soils than the spruce and firs and is characteristic of deep, shaded and moist mountain valleys and coves. It is, unfortunately, subject to the hemlock woolly adelgid (Adelges tsugae), an introduced insect, that is rapidly extirpating it as a forest tree. Less abundant, and restricted to the southern Appalachians, is Carolina hemlock (Tsuga caroliniana). Like Canada hemlock, this tree suffers severely from the hemlock woolly adelgid.

Problem: The largest theatre in the city is the 2,300 capacity Mayflower Theatre (formerly known as the Gaumont), which, as the largest theatre in Southern England outside London, has hosted West End shows such as Les Miserables, The Rocky Horror Show and Chitty Chitty Bang Bang, as well as regular visits from Welsh National Opera and English National Ballet. There is also the Nuffield Theatre based at the University of Southampton's Highfield campus, which is the city's primary producing theatre. It was awarded The Stage Award for Best Regional Theatre in 2015. It also hosts touring companies and local performing societies (such as Southampton Operatic Society, the Maskers and the University Players).
How many people can the Mayflower Theatre hold?

Answer: 2,300

Problem: Fungi communicate to coordinate and organize their growth and development such as the formation of Marcelia and fruiting bodies. Fungi communicate with their own and related species as well as with non fungal organisms in a great variety of symbiotic interactions, especially with bacteria, unicellular eukaryote, plants and insects through biochemicals of biotic origin. The biochemicals trigger the fungal organism to react in a specific manner, while if the same chemical molecules are not part of biotic messages, they do not trigger the fungal organism to react. This implies that fungal organisms can differentiate between molecules taking part in biotic messages and similar molecules being irrelevant in the situation. So far five different primary signalling molecules are known to coordinate different behavioral patterns such as filamentation, mating, growth, and pathogenicity. Behavioral coordination and production of signaling substances is achieved through interpretation processes that enables the organism to differ between self or non-self, a biotic indicator, biotic message from similar, related, or non-related species, and even filter out "noise", i.e. similar molecules without biotic content.
What 'noise' can't be filtered out?
