Answer is: platelet plug
When platelets stick to each other and to the blood
vessel they form a plug in the hole of the vessel. This process is called platelet aggregation.
Before the plug forms, a platelet will stick to the blood vessel (adhesion), change its shape
and signal other platelets to come help (activation and secretion). Then they
stick to each other (aggregation).
Answer:
Cellular reactions are made spontaneous by C coupling with ATP breakdown to ADP.
Explanation:
ATP is an energy rich compound.ATP undergo hydrolysis to generate high amount of free energy.
The free energy of ATP hydrolysis is used to make a non spontaneous reaction or thermodynamically unfavorable reaction to thermodynamically favorable manner.
Thus the cellular reactions are made spontaneous by coupling with ATP breakdown to ADP.
Geologists can 'read' rock layers using relative and absolute dating techniques. ... Relative dating arranges geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy (the rock layers are called strata).
