Natural selection is a gradual, nonrandom process by which biological traits become more or less frequent within a population. which of the following are necessary conditions for natural selection to occur within a population of staphylococcus aureus? traits that permit an individual to survive at least until reproduction will increase in frequency over time.
there is adaptation.
some individuals in the population reproduce more than others.
traits are hereditary.
some individuals within the population are optimally adapted for survival.
individuals in the population vary from one another.
deleterious (harmful) genes are removed from the population.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.

Determine the cause of death for anna garcia

we need additional information in order to determine the cause of death for anna garcia. there are at least 3 things with explanation included as to why we need them are as follows:

there would be some predate medical situations.there would be a report about the cause that why she was there for backache from the hospital.there would be a report about what she injected in her thigh that she suffered from backache.
