A. Identify the false statement. Stellar nucleosynthesis: 

1.is the term for the process by which stars create heavier elements. 
2.means stars use their small atoms to produce larger atoms. 
3.is a normal process that happens during the life cycle of stars. 
4.reactions vary and are dependent on the mass of the star. 
5.in low-mass stars like our Sun produces elements up to atomic number 26 (iron). 

B. Identify the false statement. Differentiation of large planetesimals and protoplanets: 

1.is the process by which they developed internal layering. 
2.began with heating up their component materials. 
3.used heat created by the transformation of kinetic energy from collisions into thermal energy. 
4.was inhibited if radioactive elements were present because their decay required heat input from the surroundings. 
5.resulted in a central ball of iron alloy (the core) and an outer shell of lighter rocky materials (the mantle.) 

C. Identify the false statement: The big bang theory states that: 

1.initial changes happened within minutes and later changes occurred over millions of years.
2. the temperature had to fall below 1 billion degrees to allow atoms to form. 
3.the process of atom creation, termed big bang nucleosynthesis, produced all known natural elements. 
4.as the Universe cooled, atoms and molecules accumulated in patchy clouds of gas called nebulae. 
5.nebulae condensed and heated to become spinning accretion disks, then protostars, then stars.
