This is a lava lamp. when the light bulb heats the wax, the wax rises. when the wax cools, it falls. this cycle of rising/falling is an example of:

this is an example of Convection

identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.

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.
