Answer:
Plasmin
Explanation:
Plasmin is a serine protease also referred to as fibrin digesting enzyme, it is responsible for the dissolving or degradation of blood clot. The process by which plasmin degrades blood clot is called fibrinolysis. Note that plasmin (active) is formed from an inactive enzyme called plasminogen.
 
        
             
        
        
        
Because some trait's phenotypes don't indicate their genotypes so in order to predict the phenotype of the offspring you have to know the genotypes of the parents
 
        
                    
             
        
        
        
Answer:
Water is a liquid. Water is not wet BECAUSE something is only wet when water is on that object.
Explanation:
For example, there is water is a glass cup, and then the glass cup spills onto the table, causing the table to be wet, BUT you can remove that water from the table with some paper towels or a rag. Therefore, the table is no longer wet. Or when you're out in the rain and it gets on your clothes and/or hair, then your clothes and/or hair is WET.
When you put water onto water, it's an addition of water, you don't say it's wet or wetter.
Now, let me further prove my point with a different element: Fire. Fire burns things, right? So, when fire is on an object, then that object is burned. And when you add fire to fire, it causes more fire; fire does not burn itself.
Therefore, water is NOT wet. Wet is an adjective to describe an object that has been touched by a liquid, in this case, water.
So, yeah, enjoy the rest of your day. I'm sure some would like to argue my point. Go ahead.
 
        
             
        
        
        
Answer:
By action potential nerve contract the muscle
Explanation:
The muscle contract when the nervous system sends action potential to the muscle. So the nervous system delivers signal to muscle, the first signal reaches the neuromuscular junction. The signals are passed by a chemical messenger called neurotransmitter release by motor neurons, the chemicals bring reaction and shorten the muscle fibre. When neurotransmitter are absent or reduce in concentration the process reverse and muscle relax again.
