Answer: The fossil is 11459 years old.
Explanation:
Half-life of carbon-14 = 5700 years
First we have to calculate the rate constant, we use the formula :
Now we have to calculate the age of the sample:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant =
The fossil is 11459 years old.
<h2>Answer is option "B"</h2>
Explanation:
- High temperatures are not permissive for bacterial growth and lead to cellular stress, which would lead to a shift from lysogeny to the lytic phase
- Bacteriophage infection has generally been contemplated utilizing bacterial hosts developing exponentially, with dynamic air circulation, in one of a couple of all-around examined media
- The resurgence of enthusiasm for restorative, prophylactic, and agrarian phage applications, just as developing consciousness of the significant ecological effect of phages, make it progressively imperative to contemplate the subtleties of phage-have connections under conditions that are increasingly like those experienced in indigenous habitats
- Hence, the right answer is option "B"
