Chemical senses require for transduction to occur. a. both chemical receptors and neurons b. chemical receptors to take the place of neurons c. neurons just as sight and hearing require d. each answer is partially correct

B bc in order to have a chemical reaction you have to have at least a change so something with a line of CHANGE

I'm not sure but it could be c ( not a 100% sure )

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:
