Answer:
A)11,460 years
Explanation:half of a radioactive element represent the time take for half of it's components to dissociate or disintegrate.
For carbonn14 that undergo an emmision to form a stable carbon 14,it moves thus
14C(1 part) ______14C(0.5 parts)_____14C(0.25parts)
i.e it undergo two radioactive decay which means two half lives .
Since each half life is 5780 years ,the age will be 2×half lives= 2×5780=11,460 years
Alkalinity<span> is the name given to the quantitative capacity of an aqueous solution to neutralize an acid</span>
It is called central vascular catheterization
<h3>Importance of catheterization</h3>
Catheterization is defined as the use of medical devices that can be inserted into the body and used for different medical purposes.
Vascular catheterization is a peripheral catheterization that is used to detect certain upper and lower peripheral extremity conditions.
There are different types of vascular catheterization which include:
- Arteriovenous (AV) fistula,
- Arteriovenous (AV) graft and
- Central venous catheter (CVC)
Central vascular catheterization involves Introducing a vascular catheter directly into a vessel without further advancement past the punctured vessel.
