Answer:

B. Scientific theory

Explanation:

A scientific theory explains a natural phenomenon or an occurrence in the natural world. A theory is well backed up by evidence obtained through repeated experimentation and supported by results of other researches. Theories are tested throughout time and they can be verified by other studies and even falsified.

Blizzard [7]

Predisposed mean increased the risk of developing cancer. In most case, it doesn't mean that you will 100% develop cancer but your chance will be much higher than other people.
That risk also can be increased if you doing risky behavior like sunbathing. Again, that doesn't mean you automatically get cancer someday.

Answer:

OH, H2O2 and O−2

Explanation:

Reactive oxygen species (ROS) can be defined as highly reactive chemical compounds formed from molecular oxygen (O2). ROS are generated as a normal product of cellular metabolism, and also as a response to different environmental/internal cellular stimuli (e.g., cytokines, xenobiotics, pathogenic invasion). For example, hydroxyl radicals (·OH) are a type of ROS generated in the mitochondria which are capable of inducing oxidative stress in different cells and also trigger chronic inflammation. Moreover, hydrogen peroxide (H2O2) molecules represent another type of ROS which are produced during the stereoselective deamination of amino acids, i.e., the building blocks of proteins. These molecules (H2O2) exhibit toxic effects on the cell (e.g., DNA damage). Finally, singlet oxygen (1O2) is an excited state of molecular oxygen (O2) that is generated during photosynthesis in the photosystem II (PSII) of chloroplasts.
