Answer:
The earth has different layers because as it formed, the lighter parts (like continental crust) floated to the surface, and the really heavy parts (like iron and nickel in the core) sank to the middle. It is just like when you mix oil and water: the oil will float to the surface because it is lighter (or less dense) than the water.
Erosion and deposition have a few things in common. First They both deal with rainwater and they both have to do with rivers
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.
Answer:
Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.
Hopefully this helped! :D
