Living things are NOT composed only of organic elements. Organic elements refers to compounds of Carbon, whereas living things such as Vertebrates (man, shark, lion etc) possess bones, teeth with INORGANIC components like phosphorus, magnesium, calcium.
Also, nonliving things are NOT made up of only inorganic elements. A good example is the air we breathe, it is non-living, yet contains carbon in the form of Carbiondioxide.
The amount of the 30 gram-sample that will remain after 270 years is 6.61 grams
<h3>How to determine the number of half-lives </h3>
We'll begin by obtaining the number of half lives that has elapsed. This can be obtained as follow:
- Half-life (t½) = 96 years
- Time (t) = 270 years
- Number of half-lives (n) =?
n = t / t½
n = 270 / 99
n = 2.8125
<h3>How to determine the amount remaining </h3>
- Original amount (N₀) = 30 grams
- Number of half-lives (n) = 2.8125
- Amount remaining (N) =?
The amount remaing can be obtained as follow:
N = N₀ / 2^n
N = 30 / 2^2.8125
N = 6.61 grams

Answer:
The secondary immune response is the immune response when the same antigen , memory cells that was encountered before is remembered and the immune system make antibodies to counter it.
Explanation:
There is a difference between the primary immune response and secondary immune response.
In the primary immune response occur when the immune system encountered an antigen for the first time which lead to the generation of memory cells and and the B cells with the T cells produce antibodies.
While the secondary immune response occur when the same antigen that was encountered the first time is encountered the second time and it lead to the stimulation of memory cells to produce more and high quantities of antibodies to fight foreign substances.
If the producer were to disappear then all the other organisms will either go extinct, survival of the fittest, or have to adapt to the change.
