The correct answer is C. To block UV radiation. Ozone filters the majority of UV spectra, so it protects organisms from its effects.
Answer;
-Structural isomers.
Explanation;
-Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space.
-Structural Isomers are molecules which have the same molecular formula but have different connectivities. That is; the molecules have the same molecular formula, but their atoms have different arrangements or bonds.
-For example, butane and isobutane are structural isomers, also called chain isomers. In chain isomers, the carbon atoms are connected in different orders. Isobutane and butane have a molecular formula of C4H10.
the answer is endonuclease enzyme
I) According to FDA there are about 38 toxic contaminants of bottled water may include, Chloride, Coliform, Arsenic, Iron, Manganese, phenols, Dissolved solids, Zinc,and Flouride. It is the work of FDA to allow certain levels of these contaminants in bottled water. Higher levels than the recommended levels may be toxic and dangerous to human beings.
ii) These contaminants are from different sources, for example chloride ions or chlorine is from the disinfectant used to treat water since the compounds are chloride compounds and also other byproducts of chlorine based disinfection. The CfCs is from the plastic making the bottle if water is exposed to sunlight.
Answer:
