Match each light behavior with its definition.
aalyn [17]

1-refraction

2-transmission

3-reflection

4-diffraction

<u>Explanation:</u>

Refraction is the bending of a wave when it enters a medium where its speed is different.Refraction is responsible for image formation by lenses and the eye.

Transmission of light is the moving of electromagnetic waves through a material. This transmission can be reduced, or stopped, when light is reflected off the surface or absorbed by the molecules in the material.

Reflection is when light bounces off an object.Light is reflected when there is a mismatch between materials through which the light is travelling.

Diffraction is the slight bending of light. The amount of bending depends on the relative size of the wavelength of light to the size of the opening.

7. Today you examined species diversity in one relatively simple environment. Suppose you were estimating the number of beetles
larisa86 [58]

Answer:

<em>The more the diversity in a location, the more is the diversity in organisms. </em>

<em></em>

Explanation:

Every area has a specific environment which is favorable for the survival of particular species adapted to live in that environment.

If there is such diversity in North California's environment, we will find that the population of beetles will be abundant in areas which are favorable for the survival of the beetle population. It may happen that with the passage of time, the beetle population might evolve and adapt to live in other areas too. Changes in habitat makes species diversity favorable.
