Answer:
The amount of substance present in a certain sample can be calculated through the equation,
A(t) = A(o)(0.5)^(t/h)
where At is the amount now, Ao is the original amount, t is the number of years and h is the half-life.
For a substance to at most 50% of the original amount, we get the half-life value.
At/Ao = 0.5 = 0.5^(4.5/h)
h = 4.5 billion.
Answer:
Lactic acid fermentation
Explanation:
When sugars are broken down to energy and lactic acid in animal tissues and in microorganisms it is referred to as lactic acid fermentation. Unlike alcoholic fermentation, lactic acid can be further broken down to release the locked up energy should oxygen be made available.
Sorry to burst your bubble my friend but the answer is b i hope this helps and i hope you have a great day and as always i will see you in the next video buh-bye!! (markiplier reference) :)
A.
Let's break it down:
-If the study has been conducted by multiple others and they get different results, it might be a sign that something went wrong in the experiment, and the data is unreliable. For example, if everybody else timed an event and got the same exact time except for the fact that you got a different time, you may start to suspect that you had done something wrong and the data was unusable.
<em>Hope this helped! :)</em>
