Answer: Capillaries are tiny branched blood vessels that joins the arteries to the veins
Explanation:
Capillaries are found in the junctions between arteries and veins in the tissues. 
They have the following functions:
- They have tiny walls and are tiny enough to penetrate to all parts of the body
- The thin walls help them diffuse oxygen, nutrients and waste products between cells and the blood. 
 
        
             
        
        
        
Answer:
Arthroplasty
Explanation:
The restoration of function of a joint is called Arthroplasty. The bone functions are restored by maintaining the  bones through resurfacing. Some times artificial joints are also used instead of resurfacing the existing bones. 
Arthroplasty is a method to cure Osteoarthritis, or degenerative joint disease where joint cartilages reduces with age. 
Also when medical treatments no longer make any impact on the joints of bone pain then Arthroplasty is done.
 
        
             
        
        
        
Answer:
Artifical Selection OR Cross Pollination 
Explanation:
If white roses and red roses are cross-bred by scientists, it would be artifical selection. If they were crossed in nature, it is called crossed pollination.
 
        
                    
             
        
        
        
Answer:
The double membrane of the mitochondria is highly folded,and therefore wider when unfolded than that of the nucleus.This is an adaptive feature  to increase the surface area for reactions (electrochemical  gradient) by accommodating protons pumped into it by the proton motive force(PMF)  from the matrix to set up the electrochemical gradients needed to generate the energy needed by ATPase synthase enzymes for ATPs synthesis.
Required number of protons needed to be accommodated by the double membrane to generate enough energy for ATPase synthesis,therefore larger surface area is needed.
