<h2>Co-evolution </h2>
Explanation:
A series of reciprocal adaptations in predator and prey populations describes co-dependence or co-evolution
- In co-evolution, two species which are in association evolve together due to their relationship 
- Both the species have different ancestry
- Interactions exhibited by co-evolution are: host parasite interaction, prey predator association, evolution of long proboscis in insects for taking nectar from flowers 
- Predation is a very short term behavior in which two different species interact with each other for the demand of energy, one is prey and the other is predator
- For successful predation, predator wants minimum energy investment and maximum energy 
- Increase in prey population in any given area attracts predator population, hence population of predator also increases in that area
- Increase in predator population results in decrease in prey population after some time decrease in prey population leads to decrease in predator population also

It's because all arteries carry oxygenated blood from heart to the tissue,except for arteries pulmonary which carry deoxygenated 
Blood.
All veins carry deoxygenated blood from the tissues to the heart except for pulmonary veins which carry oxygenated blood to the heart.
        
                    
             
        
        
        
In eurkaryotes, the wrapping of DNA around nucleosome introduces negative supercoiling because negative super coil knots have high twisting stress and are less tightly packed.The combine loop of protein [histone] and chromosome is called nucleosome. 
        
                    
             
        
        
        
Answer:
The muscles should not be dissected at the points of origin and insertion due to the fact that the cell structures present here are a typical in nature .
Explanation:
The origin is where the muscle joins the stationary bone. The insertion is where it joins the moving bone. ... At the bone, the fibres of the tendon are embedded in the periosteum of the bone. This anchors the tendon strongly and spreads the force of the contraction, so the tendon won't tear away easily.
