The percentage of the orignal uranium that remains after two half-lives is 25%
<h3>Data obtained from the question </h3>
- Original amount (N₀) = 100%
- Number of half lives (n) = 2
- Percentage remainig (N) =?
<h3>How to determine the percentage remaining</h3>
N = N₀ / 2ⁿ
N = 100 / 2²
N = 100 / 4
N = 25%
Thus 25% of the original sample remains

Explanation:
females have the set XX and males have XY
Answer:
b
Explanation:
<em>Let the wild type trait, the silver-white, be represented by </em><em>A</em><em> allele and the mutant trait, the golden color, be represented by </em><em>a</em><em> allele.</em>
Heterozygous wild-type male fish would be Aa
Golden female fish would be aa
Aa x aa
Aa Aa aa aa
2/4 Aa = silver-white
2/4 aa = golden color
<em>Hence, the percent likelihood of golden offspring is </em><em>2/4 or 50%.</em>
The correct option is b.
