Context and question: There are dozens of other chemical neurotransmitters that are used in more limited areas of the brain, often areas dedicated to a particular function. Serotonin, for example—the primary target of antidepressant drugs and many dietary aids—comes exclusively from a small brainstem area called the Raphe nuclei. Norepinephrine, which is involved in arousal, comes exclusively from a nearby small area called the locus coeruleus. Other neurotransmitters such as acetylcholine and dopamine have multiple sources in the brain, but are not as ubiquitously distributed as glutamate and GABA.
Norepinephrine comes from an area of the brain known as what?
Answer: locus coeruleus
Context and question: Genes can acquire mutations in their sequence, leading to different variants, known as alleles, in the population. These alleles encode slightly different versions of a protein, which cause different phenotype traits. Colloquial usage of the term "having a gene" (e.g., "good genes," "hair colour gene") typically refers to having a different allele of the gene. Genes evolve due to natural selection or survival of the fittest of the alleles.
What causes genes to evolve?
Answer: natural selection or survival of the fittest of the alleles
Context and question: In the lead up to the Iraq War, Kerry said on October 9, 2002; "I will be voting to give the President of the United States the authority to use force, if necessary, to disarm Saddam Hussein because I believe that a deadly arsenal of weapons of mass destruction in his hands is a real and grave threat to our security." Bush relied on that resolution in ordering the 2003 invasion of Iraq. Kerry also gave a January 23, 2003 speech to Georgetown University saying "Without question, we need to disarm Saddam Hussein. He is a brutal, murderous dictator; leading an oppressive regime he presents a particularly grievous threat because he is so consistently prone to miscalculation. So the threat of Saddam Hussein with weapons of mass destruction is real." Kerry did, however, warn that the administration should exhaust its diplomatic avenues before launching war: "Mr. President, do not rush to war, take the time to build the coalition, because it's not winning the war that's hard, it's winning the peace that's hard."
When did Bush declare the Iraq war?
Answer:
2003
