In the human body oxygen is absorbed by the lungs and nutrients are absorbed by the small intestine in a single-cell organism this absorption directly involves

In a single cell organism, the absorption of nutrients and control of certain things to come inside or go outside the cell directly involves the cell membrane. Although, the basic function of the cell membrane is to protect the cell from its surroundings. It also facilitates the transport of substances needed for survival.

  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.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
