When a living organism dies, it stops taking in new carbon. Thus, as the radioactive carbon-14 decays, the ratio of carbon-12 to

Alexxandr [17]

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 :

$k=\frac{0.693}{5700\text{years}}$

$k=1.21\times 10^{-4}\text{years}^{-1}$

Now we have to calculate the age of the sample:

Expression for rate law for first order kinetics is given by:

$t=\frac{2.303}{k}\log\frac{a}{a-x}$

where,

k = rate constant = $1.21\times 10^{-4}\text{years}^{-1}
t = age of sample = ?
a = let initial amount of the reactant = 100 g
x = amount decayed = 75 g
a - x = amount left after decay process = 100 - 75 = 25 g Now put all the given values in above equation, we get
[tex]t==\frac{2.303}{1.21\times 10^{-4}}\log\frac{100}{25}$

$t=11459years$

The fossil is 11459 years old.

Answer the following using directional terms specific to the dentition. a Your canine is _______________________________________

Ratling [72]

Answer:

The correct answer is - a. mesial, b. distal c. buccal d. distal e. lingual f. occlusal.

Explanation:

Mesial is the surface near the midline of the face, In dentistry, the canine is mesial to the first molar which means it is the middle of the face. The third molar is distal to the second molar.

Distal is the backside of a particular tooth in dentistry. The cheek side of the tooth known as the facial surface for the front teeth in dentistry. Lateral incisors are distal to the central incisors. Lingual is the part of the tooth near the tongue. The chewing surface of posterior teeth is also known as the occlusal.
