elixir [45]

<h3><u>Answer;</u></h3>

D) it lacks a nuclear membrane and resides inside the nucleus

<h3><u>Explanation;</u></h3>

<em><u>Nucleolus is a type of cell organelle that is located in the nucleus of an tom. </u></em>Nucleus is the control center of an atom, it controls all the cellular activities taking place in the cell.
<em><u>Nucleolus is made up of ribosomal RNA and proteins. The main function of the nucleolus is to assemble or formation of ribosomes. </u></em>Ribosomes are cell organelles that are found in the cytoplasm either attached on the endoplasmic reticulum or freely floating in the cytoplasm, where the process of protein synthesis takes place.

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.
