Potassium is most likely to be found with 6.25% of its original amount in 6 billion years because the half life of Potassium-40 is 1-1.5 billion years in graph. Thus the correct option is C.
If it half in 1 to1.5 billion years = 50% gain
1-1.5 billion years = 25%. gain
If we do that 2 more times we will get 12.5% and then 6.25% gain.
<h3>
What is half life?</h3>
Half life is defined as the time required for half of the atoms of a radioactive substance to become disintegrated.
Our estimate is about 1-1.5 billion years so repeating that about 4 times we get around 4-6 billion years for it to gain 6.25%. From this it can be concluded that Potassium-40 as since it comes the closest to remaining at 6.25% its original amount after approximately 6 billion years.

Answer:
False
Explanation:
Even desert biomes have populations of interacting species.
The molecules doesn't need energy to cross through.
The diffusion doesn't need protien, the molecules pass between phospholipids by passes protien. It moves smaller molecules. Facilitated need protien also hormone, and larger molecules.
I wish it makes sense.
<span>The reason why foods such as pineapples, pickles and tomatoes can be treated with temperatures less than 100 is because t</span>hese foods are highly acidic (pH<4.6) which provides a hurdle to microorganims.
Low-acid foods have pH values higher than 4.6, while a<span>cid foods have a pH of 4.6 or lower. They include fruits, pickles, sauerkraut, jams, jellies, marmalades, and fruit butters.</span>
