HELP ME PLEASE! List the steps scientists for using technology to find the half-life of an isotope.​
liubo4ka [24]

For radioactive materials with short half-lives, you use a very sensitive calibrated detector to measure how many counts per second it is producing. Then using the exact same set up you do the same at a latter time. You use the two readings and the time between them to determine the half-life. You don’t have to wait exactly a half-life, you can do the math with any significant time difference. Also, you don’t need to know the absolute radioactivity, as long as the set up is the same you only need to know fraction by which it changed.

For radioactive materials with long half-lives that won’t work. Instead you approach the problem differently. You precisely measure the mass of a very pure sample of the radioactive material. You can use that to calculate the number of atoms in the sample. Then you put the sample in a counter that is calibrated to determine the absolute number of disintegrations happening in a given time. Now you know how many of them are disintegrating every second. You use the following equations:

Decays per Second = (Number of Atoms) x (Decay Constant)

Half-life = (Natural Log of 2) / (Decay Constant)

And you can calculate the half-life

Hope it helps :)

ICE Princess25 [194]

Answer:

Reduce genetic diversity

Explanation:

Genetic diversity is an extremely important factor when it comes to evolution. The more diversity and variation there is within a population, the more chances a species has of surviving.

In the case of inbreeding, organisms that are related are selected to mate. This has extremely negative effects on the species such as bad health and infertility issues. In addition, because they all share the same alleles, it results in a decrease in genetic diversity, augmenting the chances of the species to disappear.

This occurs because if, for example, there is an organism that possesses a capability to resist extreme weather conditions and another that does not have this trait, there are still chances to survive, whereas if they are all the same and none of them possess this capability, the probability of this species to go extinct is higher.
