There are no statements given however a centriole is made up of microtubules triplets in a 9+0 pattern (I am unsure of what level of depth is required)
        
                    
             
        
        
        
Crossing two true breeding parents with opposite parents is the key:
Assume W is straight wing and w is curly.
Then you are crossing WW with ww
This will result in ALL Ww as offspring - so all straight offspring
If you then cross Ww x Ww you end up with a mix of 
WW (1), Ww (2) and ww (1) - so a mix of straight and curly
Answer: 
P generation has straight wings and curly wings
F1 has all straight wings
F2 has straight wings and curly wings

Answer:
The answer is ecosystem!
I like to think of an ecosystem as a web. Webs spun by spiders are often very intricate and unique. If you were to cut out a piece of a web you would lose the overall stability. JUST like a ecosystem. Ecosystems are very fragile yet beautiful and unique!
I hope this helps!
