The sensitivity of any given sensory system to the relevant stimuli can be expressed as an absolute threshold
The correct answer is eukaryotic cells.
Microscopic subunits within the cell represent the organelles found only in complex eukaryotic cell. The communication between those organelles via signal molecules are also a good example of the functioning of eukaryotic cell.
Eukaryotic cell is a cell that contains a nucleus and organelles, and is enclosed by a plasma membrane.
Answer:
asthenosphere (AkA mantle)
Explanation:
The inner core is the innermost layer so this can not be it The outer core is surrounds the inner core this is not the answer. and atmosphere is the envelope of gases surrounding the earth or another planet. and we are talking about the inside of earth.

Answer: The correct option is (the region of an enzyme that attaches to a substrate).
Explanation:
The anabolic and catabolic processes in a cell are directed and regulated by enzymes. An enzyme has the ability to speed up a metabolic reaction by lowering the amount of energy needed to start the reaction. Without enzymes, these processes would be extremely slow. They also arrange the reacting molecules in a manner that will cause the chemical change to take place rapidly. It does so through the following steps:
--> molecules of substrate combine with the enzyme at its active site.
--> the substrate molecules combine with enzyme molecules for a short time, forming an enzyme-substrate complex.
--> New substance ( product) is formed which leaves the active site of the enzyme thereby making it free for another reaction to take place.
In conclusion, the ACTIVE SITE of an enzyme is the region of an enzyme that attaches to a substrate allowing chemical reaction to take place.
