Context and question: Bacteria often attach to surfaces and form dense aggregations called biofilms or bacterial mats. These films can range from a few micrometers in thickness to up to half a meter in depth, and may contain multiple species of bacteria, protists and archaea. Bacteria living in biofilms display a complex arrangement of cells and extracellular components, forming secondary structures, such as microcolonies, through which there are networks of channels to enable better diffusion of nutrients. In natural environments, such as soil or the surfaces of plants, the majority of bacteria are bound to surfaces in biofilms. Biofilms are also important in medicine, as these structures are often present during chronic bacterial infections or in infections of implanted medical devices, and bacteria protected within biofilms are much harder to kill than individual isolated bacteria.
What is part of secondary structure in the complex formation of bacteria?
Answer: microcolonies,
Context and question: The MC controls the conferencing while it is active on the signaling plane, which is simply where the system manages conferencing creation, endpoint signaling and in-conferencing controls. This component negotiates parameters with every endpoint in the network and controls conferencing resources. While the MC controls resources and signaling negotiations, the MP operates on the media plane and receives media from each endpoint. The MP generates output streams from each endpoint and redirects the information to other endpoints in the conference.
Where does the system manage output streams while it is active?
Answer: unanswerable
Context and question: Summers in the state are generally hot and humid, with most of the state averaging a high of around 90 F (32 C) during the summer months. Winters tend to be mild to cool, increasing in coolness at higher elevations. Generally, for areas outside the highest mountains, the average overnight lows are near freezing for most of the state. The highest recorded temperature is 113 F (45 C) at Perryville on August 9, 1930 while the lowest recorded temperature is 32 F (36 C) at Mountain City on December 30, 1917.
Where was the highest known temperature in Tennessee recorded?
Answer:
Perryville
