Multiply 5730 years by 2 since two half-lives have gone by for carbon.

<u>Explanation</u>:

The half-life of a radioactive isotope depicts the measure of time that it takes half of the isotope in an example decay. On account of radiocarbon dating, the half-existence of carbon 14 is 5,730 years  

The half-life of carbon-14 is 5730 years.  

In this manner, after  

1 half-life there is 50 % = 1/2 of the first amount left.  

2 half-lives there is 25 % = 1/4 of the first amount left.  

25% is two half-lives.  

Every 50% of life requires 5730 years.  

So two half-lives require 2 × 5730

1) Describe the process of osmosis
klemol [59]
1. Osmosis is a process which occurs when there is a difference in solute concentration between two solutions separated by a semipermeable membrane.

2. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in pure solvent by osmosis.

3. The semipermeable membrane limits the diffusion of solutes in the water.

4. In an isotonic solution, the flow of water in and out of the cell is happening at the same rate. ... Water moves into and out of cells by osmosis.

5. Osmosis is basically diffusion with water. ... The most common example of facilitated diffusion is the movement of water across a cell membrane through transmembrane proteins, which requires no energy. They are simply powered by the concentration differences of the molecules between the two sides of the cell membrane.


(Hope this helped. Have a nice day.)
