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
Answer:
Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen.
The outer covering of gram-negative bacteria contains , a complex of carbohydrate and lipid responsible for symptoms such as fever and shock is referred to as a lipopolysaccharide.
<h3>What is a Lipopolysaccharide?</h3>
This refers to a large complex molecule which consists of two parts which are lipid and polysaccharide and are the main content of the outer covering of gram-negative bacteria which is often referred to as endotoxin.
It has different uses such as the initiation of prostaglandins in the body and also sending signals to the brain which increases the temperature of the body through various mechanisms.
It is also responsible for the symptoms such as fever and shock which is therefore the reason why Lipopolysaccharide was chosen as the most appropriate choice in this context.
