Images are focused by the lens onto the retina which is a face at the back of the eye upon which light sensitive cells (rods and cones) convert the incident light into electrical signals that are transmitted to the brain.
The fovea is a pit directly behind the lens on the retina that contains a concentration of light sensitive, closely packed cones (colour sensitive cells) and is responsible for sharp central vision.

D - the earth is dynamic and constantly changing
The movement of the seafloor and the tectonic plates has been responsible for the movement of the continents. The arrows in the model can be represented as "A: S, B: S, C: N, D: N"
<h3> </h3><h3>What are tectonic plates?</h3>
The big pieces of the earth's lithosphere that move is termed the tectonic plates. The movement of the plates has been given as the theory for the formation of the continents, as well as the cause of various disasters, including earthquakes and volcanos.
The model representing the movement of the plates from the center can be given in the N and the S direction. Thus, the representation of the arrows in the model will be: "A: S, B: S, C: N, D: N"
