Answer: D
Explanation: Because new dog breeds are made when people mix two different breeds together to make another breed
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. So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled. If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.
Hope this helps.
Answer:
Your body needs protein to stay healthy and work the way it should. More than 10,000 types are found in everything from your organs to your muscles and tissues to your bones, skin, and hair.

In this system the blood is pumped from the heart through blood vessels where it is transported to different organs and cells of the body instead of filling up the body cavity.
An example of a complex trait is
weight.
Complex trait or quantitative trait is a trait that doesn’t behave according to simple Mendelian inheritance laws. These traits show a continuous range of variation and are influenced by both environmental and genetic factors. It is often said that complex traits<span> are those that are influenced by more than one factor.</span>
