Answer

To determine the number of orders of magnitude, we can use the formula:

ext{Orders of Magnitude} = ext{log}_{10} rac{ ext{Number of Mitochondria in Human Cell}}{ ext{Number of Mitochondria in Yeast Cell}}

Substituting in the values:

ext{Orders of Magnitude} = ext{log}_{10} rac{10000}{10} = ext{log}_{10} 1000

Since $1000 = 10^3$ , we find:

ext{log}_{10} 1000 = 3

Therefore, there are 3 orders of magnitude more mitochondria in a human cell than in a yeast cell. Hence, the answer is B.
