Answer:
The U.S. government protects fish, a common resource, by selling fishing licenses and regulating fish lengths
Explanation:
When there is regulation about a particular goods, it reduces the rate the availability of such goods is abused, US government could actually protect fish through licensing and regulation of the type to be sold including there length which ensures the protection of the juvenile.
Answer:
D
Explanation:
it regulates the flow of water into the cell
B) After determining the optimum pH, they could vary the temperature of the environment to see if catalase is temperature specific
Enzymes are proteins which catalyze reactions by acting on substrates in order to speed up reactions- like the breakdown of large polysaccharides by amylase. Here, the enzyme catalase facilitates the breakdown of hydrogen peroxide into oxygen and hydrogen. Catalase specificity is affected by pH, temperature and the presence of inhibitors.
In temperatures beyond its optimal range, catalase may undergo changes to its physical structure called denaturation; when denatured, enzymes lose their ability to bind specifically to their substrate -i.e. substrate binding specificity is lost. H2O2 would no longer be able to bind to the active site, and thus would not be broken down.
