I would go with B, because that is what basically would move fluid in our body. Nothing else, because our heart is like a pumper, that always pumps blood through your whole body. Unless until you die, and then it stops.
Hope that this would help you!
The answer is B) Muscle fiber aka Fascicles this is what there called in the definition.
Hello!
A half-life is the amount of time it takes half of an element to decay. For example, after one of carbon's half-life, half of carbon would've decayed.
Now, we can calculate how much has decayed if 5 half lives have passed.
1 -> 50% (1) -> 25% (2) -> 12.5% (3) -> 6.25% (4) -> 3.125% (5)
Therefore, there would be 3.125% left of iodine. However, your question is asking what percent has decayed. Therefore, subtract 3.125 from 100% to get your final answer.
100 - 3.125 = 96.875
Therefore, your final answer is 96.875% of iodine has decayed if 5 half lives have passed.
Hope this helps!
