Problem: Pollination is the process by which pollen is transferred in the reproduction of plants, thereby enabling fertilisation and sexual reproduction. Most flowering plants require an animal to do the transportation. While other animals are included as pollinators, the majority of pollination is done by insects. Because insects usually receive benefit for the pollination in the form of energy rich nectar it is a grand example of mutualism. The various flower traits (and combinations thereof) that differentially attract one type of pollinator or another are known as pollination syndromes. These arose through complex plant-animal adaptations. Pollinators find flowers through bright colorations, including ultraviolet, and attractant pheromones. The study of pollination by insects is known as anthecology.
What do insects receive in return for pollination?

Answer: energy rich nectar


Problem: There are three classes of components for oxide glasses: network formers, intermediates, and modifiers. The network formers (silicon, boron, germanium) form a highly cross-linked network of chemical bonds. The intermediates (titanium, aluminium, zirconium, beryllium, magnesium, zinc) can act as both network formers and modifiers, according to the glass composition. The modifiers (calcium, lead, lithium, sodium, potassium) alter the network structure; they are usually present as ions, compensated by nearby non-bridging oxygen atoms, bound by one covalent bond to the glass network and holding one negative charge to compensate for the positive ion nearby. Some elements can play multiple roles; e.g. lead can act both as a network former (Pb4+ replacing Si4+), or as a modifier.
What components of modifiers is used for networks?

Problem: Following the success of Le Journal de Mickey (1934–44), dedicated comics magazines and full-colour comics albums became the primary outlet for comics in the mid-20th century. As in the US, at the time comics were seen as infantile and a threat to culture and literacy; commentators stated that "none bear up to the slightest serious analysis",[c] and that comics were "the sabotage of all art and all literature".[d]
In the United States in the middle of the 20th century comics were seen as a risk to culture and what?

Answer:
literacy
