The correct answer is B. Gene Flow because gene flow is the mechanism of a change in the gene composition in a population as a result of migration. PLEASE MARK ME THE BRAINIEST.
The principles comprising of cell theory are: a) All organisms are composed of one or more cells and the life processes of metabolism and heredity occur within these cells. c) Cells are the smallest living the basic units of organizations of at organisms. d) Cells are arise only by division of a previously existing cell.
According to theory of the cell, all living things are made up of cells. They could have one or many cells.
The simplest form of life is the cell.
Existing cells give rise to new ones. They are not the result of spontaneous generation.
The contemporary interpretation of the cell theory holds that: Cells experience energy flow.
DNA is genetic material that is transferred from cell to cell.
All cells share the same fundamental chemical make-up.
The fundamental ideas that provide the basis for the study of life include the cell theory, gene theory, evolution, homeostasis, and the laws of thermodynamics.

Answer:
2. The system will be defined by all the parts that act directly on the object, and the object itself.
So the parts are:
The ball.
The air.
The ground. (because this limits the motion of the ball)
The gravitational force (the force that pulls down the ball)
Why is it not the hand or you a part of the system? Because the phenomena is "a ball being dropped" the only action that you do in the ball is release it (you do not impulse it or anything) and we have our time t = 0s, when the ball is dropped, so the hand that was holding the ball is not in the picture for t ≥ 0s, then it is not part of the system.
3. Using what i wrote above, your hand is not in the system.
4. The air is important because it put resistance to the motion of the ball, if there was void, the ball would reach the ground in less time.
5. It is really hard to draw in a computer, so i will give a rough sketch of the system in this case:
Where: g = gravitational force.
H = initial height of the ball, which is really important for this problem.
Answer: climate, temperature, animals, plants, precipitation, sunlight, etc.
