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.

The answer is symplastic transport. Transport of phytohormones
such as cytokinins occurs through cytoplasm
from cell
to cell through plasmodesmata. Cytokinins travel up
the xylem and promote lateral growth. Gaseous molecules, such as
ethylene, emitted and received by plants must pass the apoplast.

Radiometric dating is a kind of technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.
