QUES: The two neurotransmitters that are used most widely in the vertebrate brain are glutamate, which almost always exerts excitatory effects on target neurons, and gamma-aminobutyric acid (GABA), which is almost always inhibitory. Neurons using these transmitters can be found in nearly every part of the brain. Because of their ubiquity, drugs that act on glutamate or GABA tend to have broad and powerful effects. Some general anesthetics act by reducing the effects of glutamate; most tranquilizers exert their sedative effects by enhancing the effects of GABA.
The neurostransmitter that usually excites targets is called what?

ANS: glutamate,

QUES: In the medieval Middle Eastern world, the physicist and Islamic scholar, Al-Farabi (Alpharabius, 872–950), conducted a small experiment concerning the existence of vacuum, in which he investigated handheld plungers in water.[unreliable source?] He concluded that air's volume can expand to fill available space, and he suggested that the concept of perfect vacuum was incoherent. However, according to Nader El-Bizri, the physicist Ibn al-Haytham (Alhazen, 965–1039) and the Mu'tazili theologians disagreed with Aristotle and Al-Farabi, and they supported the existence of a void. Using geometry, Ibn al-Haytham mathematically demonstrated that place (al-makan) is the imagined three-dimensional void between the inner surfaces of a containing body. According to Ahmad Dallal, Abū Rayhān al-Bīrūnī also states that "there is no observable evidence that rules out the possibility of vacuum". The suction pump later appeared in Europe from the 15th century.
What did Aristotle investigate to test the existence of a vacuum?

ANS: unanswerable

QUES: Increasing urbanisation of India in 7th and 6th centuries BCE led to the rise of new ascetic or shramana movements which challenged the orthodoxy of rituals. Mahavira (c. 549–477 BC), proponent of Jainism, and Buddha (c. 563-483), founder of Buddhism were the most prominent icons of this movement. Shramana gave rise to the concept of the cycle of birth and death, the concept of samsara, and the concept of liberation. Buddha found a Middle Way that ameliorated the extreme asceticism found in the Sramana religions.
What prominent icon founded Buddhism? 

ANS:
Buddha
