A. Characteristics
You would use this key and it will say something like go to 12 of it has long wings or go to 11 if it has no wings.
Answer:
A. Both waves carry energy and refract
Explanation:
There are two major types of waves viz; mechanical waves and electromagnetic eaves. Mechanical waves such as sound waves are waves that require a medium or matter to pass/travel through while electromagnetic waves like light waves do not strictly require a medium to travel i.e through vacuum.
Electromagnetic waves are transverse waves i.e their particles move perpendicularly to the direction of the wave while mechanical waves can either be transverse or longitudinal. All waves carry energy from one medium to another and are capable of refraction i.e. change of direction.
Therefore, both mechanical and electromagnetic waves carry energy and refract.
The largest population would be the producers. In an energy pyramid, the producers have the largest biomass. The smallest population would be the top predators, since there isn’t enough energy to sustain this level in the energy pyramid.
C Because the fact That best adapted animals in a population survive is part of natural selection
