which most likely explains why carlos got cancer but veronica did not?

1 veronica leads a healthier lifestyle than carlos.
2 carlos has a gene for cancer that was triggered.
3 veronica has a gene for cancer that carlos does not.

(2). Carlos has a gene for cancer that was triggered.

Explanation:

Both Carlos and Veronica have smoked, but only Carlos was diagnosed with cancer at later stages. This is because of Carlos had higher risk for developing cancer.

It is defined genetic predisposition, which represents an increase susceptibility of developing a disease based on genetic makeup of a person. It might possible that Carlos has a gene for lung cancer that was triggered due to smoking as tobacco contains mutation-causing agents, and caused cancer.

For example, people having mutation in one copy of gene p53 (a tumor suppressor gene) have higher chances of developing cancer as mutation in another copy of this gene can induce cancer.

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.
