This far-reaching civil rights act  passed by Congress in 1964, banned discrimination in public accommodations, sought to aid schools in efforts to desegregate, and prohibited federal funding of programs that permitted racial segregation. 

Civil Rights leader who delivered his “I Have a Dream” speech in Washington, DC in 1963, inspiring many Americans to demand equal treatment for African Americans in the United States. 

President John F. Kennedy’s domestic policy established to promote the expansion of programs to aid the poor, protect African Americans’ right to vote, and improve African Americans’ employment and education opportunities was called:

The term flexible response refers to President Kennedy’s aid projects, such as the Peace Corps, that would as ‘soft power’ in the Cold War with communist nations.

An allosteric transcription regulator called HisP regulates the enzymes for histidine biosynthesis in the bacterium E. coli. Histidine modulates HisP activity. On binding histidine, HisP alters its conformation, markedly changing its affinity for the regulatory sequences in the promoters of the genes for the histidine biosynthetic enzymes.   If HisP functions as a gene activator, would you expect that HisP would bind more tightly or less tightly to the regulatory sequences when histidine levels are low? Explain your answer.  

  Insulin is a small protein that regulates blood sugar level and is given to individuals who suffer from diabetes. Many years ago, diabetics were given insulin that had been purified from pig pancreas. Once recombinant DNA techniques became available, the DNA encoding insulin could be placed into an expression vector and insulin could be produced in bacteria. Which of the following is NOT a reason why purifying insulin from bacteria is a better way to produce insulin for diabetics than using insulin purified from a pig pancreas?  

  Across the plasma membrane, the Na+/K+ pump moves 3Na+ out and 2K+ in, which helps to maintain an overall negative charge in the cell (i.e., membrane potential of approximately -70 mV). Given this fact, (1) briefly explain why all cells have a negative membrane potential across the plasma membrane, then (2) consider the following scenario: What would you expect to happen to the membrane transport and cell functions if the Na+/K+ pumps were handicapped?  

  Which of the following is required for the secretion of neurotransmitters in response to an action potential?
