Answer:
Mutations in that organism, which can possibly lead to cancer (via mutations in the proto-oncogenes or tumor-suppressor genes)
I do not believe so because it is genetic, just you can't forever change a feature without plastic surgery or an accident, etc.

Answer: Y represents carbon and z is oxygen which gives CO2
Explanation: To photosynthesis to occur Carbon has to reacts with oxygen to give carbondioxide (Co2) which then combines with hydrogen (H2) and oxygen to give water (H20) the reaction gives glucose (C6H12O6).
Equation for photosynthesis = 6CO2+6H20- C6H12O6
