Answer:
C-14 from fossil had reached itshalf life
Explanation:
For radiactive isotopes (such as Carbon-14), per definition; the semi life or semi disintegration period; is defined as the time for which a certain mass isotope mass disintegrates to half of the atoms that make it up
For Carbon-14, this semi life period is 5730 years , and for the above example, as it is mentioned that we originally had 254 grams of C-14 but we currently have 127 grams (this is, exaclt half of the original mass of 254 grams), this leads us that 5730 years have passed since the original mass and the final mass (that is, one semi life period of C-14)
<span>I believe the answer is: clownfish/anemone
Clownfish is very territorial in nature. So, when they hide within the anemone, the clownfish would prevent smaller fishes from eating the anemone. In return, the anemone would prevent the bigger fish from reaching the clownfish when they hide in it.</span>
Definition. The hypothesis accepted to be true if the null hypothesis is rejected based on statistical evidence. Supplement. In the statistical testing of hypothesis, the two rival hypotheses are the null hypothesis and the alternative hypothesis.
Your answer would be photosynthesis because photosynthesis synthesis carbon based energy molecules from chloroplast inside a cell, with the outer membrance.
hope i helped my fellow brainily user :)
