Given: Generation Time 180 minutes/generation. Initial Concentration of Cell (B) = 35,000,000 cells.
How many cells will there in the media at the 10th generation? How many days will it take to produce the 10th generation?

1 day, 4 hours

Explanation:

Attached in picture.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
