The correct option is c. (20 m) .
As the formula to calculate wavelength is :
wavelength = wavespeed / frequency
gene flow or migration between two populations will help maintain similarities between the species, therefore preventing (or slowing down) the process of speciation. and when the environment changes rapidly, this can cause an overall decrease in population size because of a failure to adapt adequately to environmental changes. i hope this helped <3
Answer: An object's motion can change physically by humans, Physically by humans The action from a force can cause an object to move or can speed up accelerate, to slow down (decelerate), to stop, or to change direction.
