Which consequence of new fishing methods had the most immediate impact on the environment?Equipment that scraped the bottom destroyed fish habitats.
What were the consequences of scientific findings that Atlantic cod populations were declining? Nations enacted laws, treaties, and regulations to limit the size of commercial catches.
Which of the following is an example of bycatch? catching unwanted species of fish in a net
Answer:
The baby is a male?
Explanation:
Baby girls only contain XX chromosomes. While baby boys contain XY chromosomes.
KE= 120J............................
Answer:
The increase in temperature reflects an increase in the kinetic energy of the molecules, which favors the collision between the enzyme and substrate molecules. If the optimum pH changes, the conformation of the enzyme is altered and the substrate cannot enter its active site.
Explanation:
The relationship between pH and activity depends on the acid-base behavior of the enzyme and the substrate itself. Substrate and enzyme (active center) can contain acidic and basic functional groups, their degree of dissociation being dependent on pH, which will determine, among other aspects, the conformation of the protein, the binding capacity of the substrate to the active center of the enzyme and the transformation capacity of the substrate. The rate of an enzymatic reaction varies with increasing temperature. Such dependence reflects a double effect of temperature: positive at low values, due to the general increase that the speed of any chemical reaction experiences as temperature increases, and negative at high values, due to the thermal denaturation of the enzyme. That is, the speed of an enzymatic reaction increases as the temperature increases within a certain range, reaching a maximum value at the so-called optimal temperature. At higher values the activity decreases because the enzyme, like any other protein, undergoes denaturing processes and, therefore, inactivation.
