Four environmental factors of enzymes were tested in lab. The changing of pH‚ substrate concentrations‚ temperature‚ and an inhibitor (NaCl) and the effects it hade on the enzyme turnip peroxidase. Enzymes are biological catalysts which increase reaction rates by lowering the activation energies of substrates. A substrate is a reactant that interacts with the enzyme. The enzyme and substrate can be viewed as the recently discovered "induced fit model"‚ which suggests enzymes are flexible and dynamic

QUESTIONS chap12 3. How do the entry and exit of firms in a purely competitive industry affect resource flows and long‐run profits and losses? LO3 Answer: Entry and exit help to improve resource allocation. Firms that exit an industry due to low profits release their resources to be used more profitably in other industries. Firms that enter an industry chasing higher profits bring with them resources that were less profitably used in other industries. Both processes increase allocative efficiency

Tundra climate is probably the most biomes that are influenced by the climate. Four principal factors that affect Tundra climate are the solar radiation‚ the temperature‚ and precipitation as well as air pressure. Solar radiation is very weak in Arctic or Antarctic tundra which is why polar tundra are often covered in the snow compared to other tundra around the world. However‚ in summer‚ there is more solar radiation which gets the temperature to rise. Alpine tundra zone gets more solar radiation

Social stratification is a characteristic of all society. We have also seen that classes and individuals are rated high or low on the basis of characteristics possessed by them according to the social value scale.
