Human Hormone F is a peptide hormone that causes increased heart rate in humans.  When human Hormone F is injected into a mouse’s bloodstream, no changes are observed in the mouse’s heart rate.    
 

Based on this information and your knowledge about biology, select true or false for each of the following statements.
	
  		
	True 	False 		
				The lack of response could result from this particular mouse having a genetic mutation that prevents expression of its own Hormone F.
				The lack of response could be because Hormone F must be injected directly into heart tissue to have an effect on this mouse’s heart.
				The lack of response could be because the dose of Hormone F injected was too low to observe an effect in this mouse.
				The lack of response could result from this species of mice having genetic differences that prevent their Hormone F receptor from binding human Hormone F.
 Your answer should have exactly 3 paragraphs. Make sure that the first paragraph starts with the word "activity" and that each paragraph is separated by two new lines.
