Answer: Light Refraction

Explanation:

Light rays travel in straight lines. When they strike an opaque surface, the rays bounce, and light is reflected back to your eye so that you see an image. When light strikes a transparent object, some of the light passes through. If that light strikes the object straight on, it continues to travel in a straight line. If the light enters the transparent object at an angle, though, it changes direction, bending.This bending of light is called refraction. Refraction occurs because light entering an object slows down. When it enters at an angle, one side of the light ray enters before the other, slowing down first.Looking from above, an object under water appears larger than it does in air. It's not that the image the light gave our eyes is bigger. It's that the image is actually closer to our eyes, since the light is not passing straight down, but is instead bending relative to the water's surface. Light passing straight down would be perpendicular to the water's surface, like the vertical line on the letter T.

andrey2020 [161]

Answer:

Option A: True

Explanation:

Insectivorous birds such as bluebirds, dippers and flycatchers prefer to eat medium-sized insects. This is because like most birds, they love easy and satisfying meals. To the birds, a medium-sized insect is a good compromise because it is quite easy to chew and digest and at the same time, easy to find.

As a result, most insectivorous birds prefer to get their daily ration of proteins from the medium-sized birds.

Mandarinka [93]

Answer:

resource partitioning

Explanation:

Based on the scenario being described within the question it can be said that this is an example of resource partitioning. This term refers to when a species divides the limited resources in order to avoid competition within it's environment. Such as the two species of mice are doing by feeding in on the same resources at different times in order to avoid competition and conflict between each other. Thus allowing them to co-exist within the same environment.
