1.) B.) plants have chloroplasts
2.) B.) to prevent hydrophilic heads from sticking
3.) B , D and maybe C?
Answer:
A.
Explanation:
A large amount of granulation tissue converted to dense irregular collagenous connective tissue during tissue repair
To answer your question the name of this process is, Natural Selection.
Given that,
The speed of a wave, v = 200 m/s
Wavelength, ![\lambda=2\ m](https://tex.z-dn.net/?f=%5Clambda%3D2%5C%20m)
We need to find the frequency of this wave. The relation between wavelength, frequency and the speed is given by :
![v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{200\ m/s}{2\ m}\\\\f=100\ Hz](https://tex.z-dn.net/?f=v%3Df%5Clambda%5C%5C%5C%5Cf%3D%5Cdfrac%7Bv%7D%7B%5Clambda%7D%5C%5C%5C%5Cf%3D%5Cdfrac%7B200%5C%20m%2Fs%7D%7B2%5C%20m%7D%5C%5C%5C%5Cf%3D100%5C%20Hz)
So, the frequency of this wave is 100 Hz.
