Question: The avian circulatory system is driven by a four-chambered, myogenic heart contained in a fibrous pericardial sac. This pericardial sac is filled with a serous fluid for lubrication. The heart itself is divided into a right and left half, each with an atrium and ventricle. The atrium and ventricles of each side are separated by atrioventricular valves which prevent back flow from one chamber to the next during contraction. Being myogenic, the heart's pace is maintained by pacemaker cells found in the sinoatrial node, located on the right atrium. The sinoatrial node uses calcium to cause a depolarizing signal transduction pathway from the atrium through right and left atrioventricular bundle which communicates contraction to the ventricles. The avian heart also consists of muscular arches that are made up of thick bundles of muscular layers. Much like a mammalian heart, the avian heart is composed of endocardial, myocardial and epicardial layers. The atrium walls tend to be thinner than the ventricle walls, due to the intense ventricular contraction used to pump oxygenated blood throughout the body. Avian hearts are generally larger than mammalian hearts when compared to body mass. This adaptation allows more blood to be pumped to meet the high metabolic need associated with flight.
Is there an answer to this question: Where is the heart contained in the avian circulatory system?

Answer: fibrous pericardial sac


Question: In 1899 the state legislature passed a new constitution, with requirements for poll taxes and literacy tests for voter registration which disfranchised most black Americans in the state. Exclusion from voting had wide effects: it meant that black Americans could not serve on juries or in any local office. After a decade of white supremacy, many people forgot that North Carolina had ever had thriving middle-class black Americans. Black citizens had no political voice in the state until after the federal Civil Rights Act of 1964 and Voting Rights Act of 1965 were passed to enforce their constitutional rights. It was not until 1992 that another African American was elected as a US Representative from North Carolina.
Is there an answer to this question: Being excluded from doing what, made it so that black people could not serve on juries or in public office?

Answer: voting


Question: Immanuel Kant (1724–1804) has formulated an individualist definition of "enlightenment" similar to the concept of bildung: "Enlightenment is man's emergence from his self-incurred immaturity." He argued that this immaturity comes not from a lack of understanding, but from a lack of courage to think independently. Against this intellectual cowardice, Kant urged: Sapere aude, "Dare to be wise!" In reaction to Kant, German scholars such as Johann Gottfried Herder (1744–1803) argued that human creativity, which necessarily takes unpredictable and highly diverse forms, is as important as human rationality. Moreover, Herder proposed a collective form of bildung: "For Herder, Bildung was the totality of experiences that provide a coherent identity, and sense of common destiny, to a people."
Is there an answer to this question: Who said the following statement? "Enlightenment is man's emergence from his self-incurred immaturity".

Answer: Immanuel Kant
