<h3><u>Answer;</u></h3>
half the sample to decay.
<h3><u>Explanation;</u></h3>
The half-life of a radioisotope is the amount of time it takes for<em><u> half the sample to decay. </u></em>
- <em><u>Radioactive particles or nuclides undergoes the process called radioactivity </u></em>which is the spontaneous decay of radioactive materials to emit radiation such as beta particle, alpha particle and also associated with energy loss.
- <em><u>Half-life is the time taken by a radioactive substance or material to decay by half of the original isotope to decay.</u></em> For instance; <em><u>when the half life of 100 g of substance X is 5 years, this means that after five years only 50 g of the substance would remain.</u></em>
b is going to be the answer to that
it is B cells produce antibodies and T cells destroy infected cells
Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.
