Answer:
After 48 hours amount left = 6.25 g
Explanation:
Given data:
Half life of potassium = 12 hours
Total mass = 100 g
Mass left after 48 hours = ?
Solution:
Number of half lives passed:
Number of half lives = Time elapsed / half life
Number of half lives = 48 hours/ 12 hours
Number of half lives = 4
At time zero = 100 g
At first half life = 100 g/ 2 = 50 g
At 2nd half life = 50 g/2 = 25 g
At 3rd half life = 25 g/2 = 12.5g
At 4th half life = 12.5 g/2 = 6.25 g

<span>The mechanism that affected the gene pool of the immigrants that entered the United States through Ellis Island from 1892 to 1954 is B. gene flow. Gene flow is the transfer of genes or alleles from one population to another. The migration of millions of individuals from countries across the Atlantic Ocean to the United States is responsible for the changes in the gene pool of the immigrants.</span>
