<h3><u>Answer;</u></h3>
Potassium-40 has a half life of 1.25 billion years.
<h3><u>Explanation;</u></h3>
New amount = Original amount × (1/2)^n ; where n is the number of half lives.
Original amount is 50 atoms
New amount is 25 atoms
Therefore;
25 = 50 × (1/2)^n
1/2 = (1/2)^n
Thus; n = 1
n = 1 which is equivalent to 1.25 billion years
Therefore;
<u>Potassium-40 has a half life of 1.25 billion years.</u>

Abiotic means not alive, and the insects and fish options are alive, so we can eliminate those. Sunlight and rocks are left. Of these, the rock would not affect the water lilies, not as much as sunlight at least. Without sunlight, the water lilies would not be able to grow and thrive as all plants/flowers have sunlight as one of their basic needs, so sunlight must be the answer.
