Answer:
Soil erosion causes siltation in rivers, dams, etc. In some areas, huge river deltas are formed (such as River Nile delta) because of soil erosion. Such places are good for agriculture but not good for urbanization. However, some people do not care about it, they just want to construct buildings on alluvium type soils.
C: from what I can see in the graph
Exposure to environmental tobacco smoke causes approximately 45 to 46,000 non smokers to die of heat diseases annually. Smoking harms the cardiovascular system in many ways which include; damaging the lining of arteries, reduces HDL, good choresterol, Raises LML, bad cholesterol, increases blood pressure and heart rate, it also causes the platelets to stick together in the blood stream and speeds the development of fatty deposits in the arteries among other risk factors.
Enzymes are classified and named according to the<u> types of reactions they catalyze.</u>
Explanation:
According to the International Union of Biochemistry and Molecular Biology nomenclature of enzyme classification, enzymes are classified depending upon the reactions they catalyze and how the reaction transforms the substrate and forms new products.
Based on the reactions:
Addition reaction (removal of a water molecule): hydrases or hydrolases like esterases, nucleases etc
Electron transfer reaction: Oxidases and dehydrogenases
Radical transfer reaction: Transglycosidases, transaminases, etc
Splitting or C-C bond formation: Desmolases
Structural or geometrical change: Isomerases
Hydrolysis of phosphate bonds to join molecules: Ligases
Based on the general principle of recommendations, enzymes are suffixed with –ase depending upon the catalytic reaction and substrate.
