Input: You couldnt survive without your skin. It has many important functions. The main function of the skin is controlling what enters and leaves the body. It prevents the loss of too much water from the body. It also prevents bacteria and other microorganisms from entering the body. The skin helps maintain a constant body temperature. It keeps the body cool in two ways. Sweat from sweat glands in the skin evaporates to cool the body. Blood vessels in the skin dilate, or widen. This action increases blood flow to the body surface. This allows more heat to reach the surface. The heat is then able to radiate off the body. The opposite happens to retain body heat. Blood vessels in the skin constrict, or narrow. This decreases blood flow to the body surface. This reduces the amount of heat that reaches the surface. When this happens, less heat can be lost to the air.

Does the response "Blood vessels dilate" correctly answer the question "What increases blood flow to the body's surface?"?

Alexander Sergeyevich Pushkin (/'pUSkIn/; Russian: Aleksandr Sergeevich Pushkin, tr. Aleksandr Sergeyevich Pushkin; IPA: [aljI'ksandr sjI'rgjejIvjItc 'puskjIn]; 6 June [O.S. 26 May] 1799 - 10 February [O.S. 29 January] 1837) was a Russian author of the Romantic era who is considered by many to be the greatest Russian poet and the founder of modern Russian literature. Pushkin was born into Russian nobility in Moscow. His matrilineal great grandfather was Abram Gannibal, who was brought over as a slave from what is now Cameroon. Pushkin published his first poem at the age of fifteen, and was widely recognized by the literary establishment by the time of his graduation from the Tsarskoye Selo Lyceum. While under the strict surveillance of the Tsar's political police and unable to publish, Pushkin wrote his most famous play, the drama Boris Godunov. His novel in verse, Eugene Onegin, was serialized between 1825 and 1832. Notoriously touchy about his honour, Pushkin fought as many as twenty-nine duels, and was fatally wounded in such an encounter with Georges-Charles de Heeckeren d'Anthes. Pushkin had accused D'Anthes, a French officer serving with the Chevalier Guard Regiment of attempting to seduce the poet's wife, Natalya Pushkina.

(CNN) -- Women seeking an abortion in Texas will have to view a picture of the embryo or fetus and hear a description of its development before having the procedure, under a law that takes effect September 1. The bill stirred some controversy in Texas, but it easily passed through the state House and Senate, both of which are controlled by Republicans. It was signed into law Thursday by Republican Gov. Rick Perry. The law says that at least 24 hours before an abortion is performed, women must undergo a sonogram, a procedure that uses ultrasound to create an image. The doctor, then, is required to give, "in a manner understandable to a layperson, a verbal explanation of the results of the sonogram images, including a medical description of the dimensions of the embryo or fetus, the presence of cardiac activity, and the presence of external members and internal organs," the law states. There are some exceptions, including pregnancies that resulted from sexual assault, incest or other violations of law. Women seeking abortions also are exempt if the fetus has been found to have an irreversible medical condition that will cause a disability. "Governor Perry was pleased to sign this important legislation, which bolsters our efforts to protect life by ensuring Texans are fully informed when considering such an important decision," said his deputy press secretary, Lucy Nashed. Critics say the new law is unnecessary. "What no one is focusing on is that this is a mandate to humiliate women who want an abortion," said Yvonne Gutierrez, vice president for public affairs at the Planned Parenthood Trust of South Texas. Texas already requires a 24-hour consent period, and the new law will simply add emotional and financial costs to those seeking abortions, she said.

He repeatedly calls on his followers to embrace martyrdom since "The walls of oppression and humiliation cannot be demolished except in a rain of bullets." For those yearning for a lost sense of order in an older, more tranquil world, he offers his "Caliphate" as an imagined alternative to today's uncertainty. For others, he offers simplistic conspiracies to explain their world. Bin Laden also relies heavily on the Egyptian writer Sayyid Qutb. A member of the Muslim Brotherhood executed in 1966 on charges of attempting to overthrow the government, Qutb mixed Islamic scholarship with a very superficial acquaintance with Western history and thought. Sent by the Egyptian government to study in the United States in the late 1940s, Qutb returned with an enormous loathing of Western society and history. He dismissed Western achievements as entirely material, arguing that Western society possesses "nothing that will satisfy its own conscience and justify its existence." Three basic themes emerge from Qutb's writings. First, he claimed that the world was beset with barbarism, licentiousness, and unbelief (a condition he called jahiliyya, the religious term for the period of ignorance prior to the revelations given to the Prophet Mohammed). Qutb argued that humans can choose only between Islam and jahiliyya. Second, he warned that more people, including Muslims, were attracted to jahiliyya and its material comforts than to his view of Islam; jahiliyya could therefore triumph over Islam. Third, no middle ground exists in what Qutb conceived as a struggle between God and Satan. All Muslims-as he defined them-therefore must take up arms in this fight. Any Muslim who rejects his ideas is just one more nonbeliever worthy of destruction. Bin Laden shares Qutb's stark view, permitting him and his followers to rationalize even unprovoked mass murder as righteous defense of an embattled faith. Many Americans have wondered, "Why do 'they' hate us?" Some also ask, "What can we do to stop these attacks?" Bin Laden and al Qaeda have given answers to both these questions.
