Variations, traits

Not all members of a species are the same. Every species exhibit variations. Traits, like eye color, are passed from parent to offspring.

Genetic variation is the subtle differences in the DNA sequence in each individual’s genomes. Genetic variation results in various forms or alleles of genes that determines distinct traits such as eye color, skin color, shape of face, and hair color that can be passed on from parents to offspring.

Reactive oxygen species (ROS) are unstable, or reactive, compounds that result from the partial reduction of oxygen. ROS can cau
soldier1979 [14.2K]

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.
