Answer:
Experiment 4. Relaxed, the drug will stop the calcium so that it does not act on the troponin
Experiment 5. Contraction: In order for the muscle to relax, the actin and tropomyosin union must occur.
Experiment 6. Relaxation: the release of the actin-myosin complex occurs with consumption of ATP, thus it slides and generates contraction, by adding a hydrolyzable analog, this reaction is avoided giving rise to a prolonged actin-myosin binding which leads to relaxation while last effect.
Experiment 7. Ca2 + Contraction is very necessary so that during muscle contraction troponin can be extracted.
 
        
             
        
        
        
Osmosis is a passive transport which moves water molecules from higher to lower gradient.
<span>Osmosis then is the movement of water particles from which has water and from which has not and to provide it with the sufficient H2O.<span> 
</span></span><span>The concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences.<span>

<span>We have two surfaces of nerve cell the outer and inner surface 
- resting : when the outer layer ion charges more positively than the inner layer - depolarization : we have the counter part of this state 
- repolarization : return to the polarization 
- hyperpolarization : the inner negative ion charges will be more negative even more than the resting potential
I hope that this is the answer that you were looking for and it has helped you.
