The yeast did not produce the carbon dioxide needed for the bread to rise.
Explanation:
The yeast for making the bread did not produce carbon dioxide needed for the bread to rise is the reason why the bread was flat and lacked air bubbles.
The yeast produces the rising agent which is the carbon dioxide gas.
- Yeast is a micro-organism that breaks sugar down into alcohol, carbon dioxide and other products.
- This process is known as fermentation.
- The volume of the dough increases as carbon dioxide forms.
- A bread in which the dough does not rise must lacked yeast or so.

I believe the correct response would be A. Energy being absorbed, as temperature increase must for instance occur for the reaction to occur, this increase in temperature for the reacting substances indicates energy being absorbed as the reaction proceeds.
6.023*1023 He atoms=1 mole He
1.23×1024 helium atoms=1.23×1024/6.023*1023 =2.042 mole He
one mole He=4.0 gm
2.042 mole He=2.042*4.0=8.168 gm
answer in grams of Helium is 8.168 gm
