The answer is C. If the Fours were all the way on the left it would make all of the zeros Significant figures.
Refraction is the phenomenon of change in the speed of light when the light when passes from the medium of one optical density to a medium of another optical density. The light rays also show a bending when passing through the interface of such a medium.
<h3>What causes wave refraction?</h3>
Refraction is the bending of waves due to a change in speed as they travel through different media. Waves may accelerate or decelerate when they go obliquely from one medium to another. The waves will bend more dramatically as their speed changes.
<h3>What characteristics does a wave have?</h3>
The following characteristics of waves:
- Refraction is the bending of waves as they move from one medium to another due to a change in their speed.
- Waves may speed up or slow down as they transition from one medium to another at an angle.

Answer:
ANIMAL CELL
Animal cells are generally small in size.
They don't have a cell wall
Except the protozoan Euglena, no animal cell possesses plastids.
Vacuoles in animal cells are many, small and temporary.
Animal cells have a single highly complex and prominent Golgi apparatus.
Animal cells have centrosome and centrioles.
PLANT CELL
Plant cells are larger than animal cells.
The plasma membrane of plant cells is surrounded by a rigid cell wall of cellulose.
They have Plastids
Most mature plant cells have a permanent and large central sap vacuole.
Plant cells have many simpler units of Golgi apparatus, called dictyosomes.
Plant cells lack centrosome and centrioles.
