I am just trying to reach a high level on to get people to answer my questions and have many pts. I don't care about your question, so I am just telling you that you said this because I need points to reach a high level and be a trusted user on this platform. Please do not report this comment because I told you previously that I am trying to get points and reach a high level. Good luck!

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
