Sexual reproduction involves sex cells. The female reproductive cell is a(an) and the male reproductive cell is a(an)
. The male and female sex cells combine in a process called fertilization to form a
that eventually grows and develops into an offspring. Sexual reproduction involves sex cells. The female reproductive cell is a(an)

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

i think the answer is a, hope this : )
