A : a car driving down a hill
Newton's law of gravity defines the attractive force between all objects that possess mass. Understanding the law of gravity offers profound insights into the way our universe functions. Newton, upon observing an apple fall from a tree, began to think along the following lines: The apple is accelerated, since its velocity changes from zero as it is hanging on the tree and moves toward the ground. Thus, by Newton's 2nd Law there must be a force that acts on the apple to cause this acceleration. Let's call this force "gravity", and the associated acceleration the "acceleration due to gravity". Then imagine the apple tree is twice as high. Again, we expect the apple to be accelerated toward the ground, so this suggests that this force that we call gravity reaches to the top of the tallest apple tree. <span>Newton knew that the force which caused the apple's acceleration (gravity) must be dependent upon the mass of the apple. And since the force acting to cause the apple's downward acceleration also causes the earth's upward acceleration (Newton's third law), that force must also depend upon the mass of the earth. </span>
Answer:
The plant which I think it says clover i can see
Explanation:
plants are primary sources of energy because it makes it own food and doesn't take form other animals.
Most flowers are bright in color because it is attractive to pollinators.
<h3>What is adaptation?</h3>
An adaptation is any phenotypic trait that confers an evolutionary advantage to an individual.
Most flowers are bright in color because it is attractive to pollinators, which is required to transport pollen to other flowers and thus increase the genetic variation in the plant population.
In conclusion, flowers are bright in color to attract pollinators.

Answer:
The hierarchy of selection. We most typically think of natural selection working at the level of the individual, favoring those better at leaving behind more individual descendants. However, with a little imagination, we can see how natural selection might work at other levels of biological organization as well.
