It takes matilde twice as long to complete a research project as it takes raphael to do the same research project. they found that if they worked together they could finish similar project in 1 hour. how long would it take each of them working alone to finish the research project?

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.

explanation:

iron would move it is magnetic there is a mag field around the current in the wire

graph question answered .. you think better when you are relaxed and happy

  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.
