Answer: Fossils and primitive drawings in several digs around the world continents.
Explanation: I would expect to find fossils and primitive drawings of these several thousand African migrants on different areas around the world. I would like to find primitive bones, specially skulls and teeths and stones with drawings and old writings representing the life of these small population in Africa who made the entire human population.
 
        
             
        
        
        
The difference in air pressure which is created by the molecules in air help to move kite up into the air. 
<u>Explanation:</u>
When air moves faster, pressure of air becomes less. Air moves at a faster speed above the kite than below it and so its pressure is less on top of kite. The air pressure below kite is less. This difference in pressure results in uplifting of kite. Molecules of air with high pressure exerts more force on kite from bottom and thus pushing it up in air.
The greater is the difference between air pressure above kite and air pressure below kite, greater is the amount of force exerted on kite and hence, it reaches a greater height.

One difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together (option C). 
<h3>What are cancer cells?</h3>
Cancer is a disease in which the cells of a tissue undergo uncontrolled (and often rapid) proliferation. 
When normal cells become cancerous, they lose the ability to regulate cell division, hence, they continue to divide excessively. 
Normal cells are characterized by their ability to regulate cell division during the cell cycle. 
Therefore, one difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together.
