The elements listed in the choices are radioactive materials. These materials are very unstable because of the high neutron-to-proton ratio in the nucleus. Because of this, they spontaneously undergo nuclear reactions by giving off sub-particles in order to lower the ratio. They emit radiation in the form of alpha, beta or gamma.
Half-life is the length of time it needs to completely react half of the original amount. For example, it would take Bismuth 60.5 seconds to use up half of its amount. Therefore, the lower the half-life the faster the reaction is and the lesser the residual amount will be. With that being said, the answer would be Bismuth because it only takes seconds.
When a population exhibits adaptation, it indicates that the population has responded to a pressure from the environment in a way that causes the prevalence of beneficial features to rise over time.
Natural selection only affects heritable traits in populations, favoring advantageous alleles and reducing the frequency of harmful alleles, a process known as adaptive evolution. Natural selection only affects heritable traits in populations. However, natural selection affects whole organisms rather than specific alleles. A person may have a genotype that is extremely advantageous and a phenotype that, for example, boosts fecundity, but if that person also contains an allele that causes a fatal childhood ailment, the fecundity phenotype won't be passed on to the next generation.
