The half-life of Carbon-14 is 5730 years. Suppose a fossil is found with 50% of Carbon-14 as compared to a living sample. How ol

Answer:

5732 years

Explanation:

Radioactive decay can be determined by using the equation:

N_t = N_0e^{- \lambda t}

where;

N_t = number of decayed atoms at time (t)

N_0 = initial number of decayed atoms

\lambda = decay constant

So, if we equate the natural log of the above; we have:

In(N_t) = In(N_0)-\lambda t

\frac{In(N_t)} { In(N_0)}} = -\lambda t

where;

\lambda = \frac{0.693}{t_{1/2}}

\lambda = \frac{0.693}{5730}

\lambda = 1.209*10^{-4

In(\frac{50}{100}) =-(1.209 *10^{-4})*t

-0.693 = -(1.209*10^{-4})*t

t= \frac{0.693}{1.209*10^{-4}}

t = 5732.01 years

t = 5732 years.

Hence, the fossil is 5732 years old.

4. Anabolic

5. Catabolic

6. Catabolic

7. Anabolic

8. Anabolic

Explanation: Catabolic reactions are exothermic meaning they release alot of energy and electrons, whereas anabolic reactions are endothermic using up alot of energy for production and storage. Breaking down glucose to produce ATP is an example of a catabolic reaction. Using fatty acids and lipids to make adipose tissues is an example of an anabolic reaction, breaking down adipocytes for production of heat and ketone bodies is catabolic.
