Problem: Insects were among the earliest terrestrial herbivores and acted as major selection agents on plants. Plants evolved chemical defenses against this herbivory and the insects, in turn, evolved mechanisms to deal with plant toxins. Many insects make use of these toxins to protect themselves from their predators. Such insects often advertise their toxicity using warning colors. This successful evolutionary pattern has also been used by mimics. Over time, this has led to complex groups of coevolved species. Conversely, some interactions between plants and insects, like pollination, are beneficial to both organisms. Coevolution has led to the development of very specific mutualisms in such systems.
Insects show how toxic they are with what kind of colors?
The answer is the following: warning colors

Problem: On the exterior, the verticality is emphasised in a major way by the towers and spires and in a lesser way by strongly projecting vertical buttresses, by narrow half-columns called attached shafts which often pass through several storeys of the building, by long narrow windows, vertical mouldings around doors and figurative sculpture which emphasises the vertical and is often attenuated. The roofline, gable ends, buttresses and other parts of the building are often terminated by small pinnacles, Milan Cathedral being an extreme example in the use of this form of decoration.
Which cathedral demonstrates a drastic example of termination with small pinnacles?
The answer is the following: Milan Cathedral

Problem: The event of the Protestant Reformation and the politics that ensued has been cited as the origins of German identity that arose in response to the spread of a common German language and literature. Early German national culture was developed through literary and religious figures including Martin Luther, Johann Wolfgang von Goethe and Friedrich Schiller. The concept of a German nation was developed by German philosopher Johann Gottfried Herder. The popularity of German identity arose in the aftermath of the French Revolution.
How was early German culture developed?
The answer is the following: literary and religious figures

Problem: From the end of the 1980s to the early 1990s, the FBI reassigned more than 300 agents from foreign counter-intelligence duties to violent crime, and made violent crime the sixth national priority. With reduced cuts to other well-established departments, and because terrorism was no longer considered a threat after the end of the Cold War, the FBI assisted local and state police forces in tracking fugitives who had crossed state lines, which is a federal offense. The FBI Laboratory helped develop DNA testing, continuing its pioneering role in identification that began with its fingerprinting system in 1924.
What priority were violent crimes in the 1990s, according to the FBI?
The answer is the following:
sixth national priority
