Problem: Predation:

While successful predation results in a gain of energy, hunting invariably involves energetic costs as well. When hunger is not an issue, in general most predators will not seek to attack prey since the costs outweigh the benefits. For instance, a large predatory fish like a shark that is well fed in an aquarium will typically ignore the smaller fish swimming around it (while the prey fish take advantage of the fact that the apex predator is apparently uninterested). Surplus killing represents a deviation from this type of behaviour. The treatment of consumption in terms of cost-benefit analysis is known as optimal foraging theory, and has been quite successful in the study of animal behavior. In general, costs and benefits are considered in energy gain per unit time, though other factors are also important, such as essential nutrients that have no caloric value but are necessary for survival and health.

A: gain of energy

Problem: In England, one of the few licensed venues The Eclipse attracted people from up and down the country as it was open until the early hours. The Criminal Justice and Public Order Act 1994 was a government attempt to ban large rave dance events featuring music with "repetitive beats". There were a number of abortive "Kill the Bill" demonstrations. The Spiral Tribe at Castle Morten was probably the nail in the coffin for illegal raves, and forced through the bill, which became law, in November 1994. The music continued to grow and change, as typified by Leftfield with "Release the Pressure", which introduced dub and reggae into the house sound, although Leftfield had prior releases, such as "Not Forgotten" released in 1990 on Sheffield's Outer Rhythm records.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Beyonce's first solo recording was a feature on Jay Z's "'03 Bonnie & Clyde" that was released in October 2002, peaking at number four on the U.S. Billboard Hot 100 chart. Her first solo album Dangerously in Love was released on June 24, 2003, after Michelle Williams and Kelly Rowland had released their solo efforts. The album sold 317,000 copies in its first week, debuted atop the Billboard 200, and has since sold 11 million copies worldwide. The album's lead single, "Crazy in Love", featuring Jay Z, became Beyonce's first number-one single as a solo artist in the US. The single "Baby Boy" also reached number one, and singles, "Me, Myself and I" and "Naughty Girl", both reached the top-five. The album earned Beyonce a then record-tying five awards at the 46th Annual Grammy Awards; Best Contemporary R&B Album, Best Female R&B Vocal Performance for "Dangerously in Love 2", Best R&B Song and Best Rap/Sung Collaboration for "Crazy in Love", and Best R&B Performance by a Duo or Group with Vocals for "The Closer I Get to You" with Luther Vandross.
What solo album did Beyonce release in 2003?
A: Dangerously in Love

Context and question: Polemics about humanism have sometimes assumed paradoxical twists and turns. Early 20th century critics such as Ezra Pound, T. E. Hulme, and T. S. Eliot considered humanism to be sentimental "slop" (Hulme)[citation needed] or "an old bitch gone in the teeth" (Pound) and wanted to go back to a more manly, authoritarian society such as (they believed) existed in the Middle Ages. Postmodern critics who are self-described anti-humanists, such as Jean-Francois Lyotard and Michel Foucault, have asserted that humanism posits an overarching and excessively abstract notion of humanity or universal human nature, which can then be used as a pretext for imperialism and domination of those deemed somehow less than human. "Humanism fabricates the human as much as it fabricates the nonhuman animal", suggests Timothy Laurie, turning the human into what he calls "a placeholder for a range of attributes that have been considered most virtuous among humans (e.g. rationality, altruism), rather than most commonplace (e.g. hunger, anger)". Nevertheless, philosopher Kate Soper notes that by faulting humanism for falling short of its own benevolent ideals, anti-humanism thus frequently "secretes a humanist rhetoric".
What was the main reason they agreed with the beliefs?

Question: During mutualistic symbioses, the host cell lacks some of the nutrients, which are provided by the endosymbiont. As a result, the host favors endosymbiont's growth processes within itself by producing some specialized cells. These cells affect the genetic composition of the host in order to regulate the increasing population of the endosymbionts and ensuring that these genetic changes are passed onto the offspring via vertical transmission (heredity).
Is there an answer to this question: What is given to the host cell?

Answer: nutrients

QUES: Hydrogen production technologies been a significant area of solar chemical research since the 1970s. Aside from electrolysis driven by photovoltaic or photochemical cells, several thermochemical processes have also been explored. One such route uses concentrators to split water into oxygen and hydrogen at high temperatures (2,3002,600 C or 4,2004,700 F). Another approach uses the heat from solar concentrators to drive the steam reformation of natural gas thereby increasing the overall hydrogen yield compared to conventional reforming methods. Thermochemical cycles characterized by the decomposition and regeneration of reactants present another avenue for hydrogen production. The Solzinc process under development at the Weizmann Institute uses a 1 MW solar furnace to decompose zinc oxide (ZnO) at temperatures above 1,200 C (2,200 F). This initial reaction produces pure zinc, which can subsequently be reacted with water to produce hydrogen.

What is one of the thermochemical processes that has been explored besides electrolysis?
What is the answer?
ANS:
