Answer: The correct option is
E. a woodpecker using his sharp beak
Explanation:
This is because a structural adaptations refer to characteristics or traits that animals possess and they use in order to adapt or survive in their environment. These refer to the physical characteristics of the animals.
From the question, a wood pecker using a sharp beak is an example of structural because the beak is the characteristics the wood pecker is using to survive in it's environment.
Correct Question:
Two sound waves (wave X and wave Y) are moving through a medium at the same speed. If wave X has a greater frequency than wave Y, then wave X
A. has a lower amplitude.
B. has a shorter wavelength.
C. has a longer wavelength.
D. has a greater amplitude.
Answer:
C. has a longer wavelength.
The basic equation of frequency and speed are
velocity = frequency x wavelength
When both waves' velocities are the same then
v1 = v2
f-1 x wavelenght-1 = f-2 x wavelenght-2
Now increasing frequency of wave X will increase the wavelength of wave Y for the equations to be equal.
