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.
 
        
             
        
        
        
We know that height in humans is a polygenic trait because it has a lot of variation. The height gene is controlled by at minimum three genes with six different alleles. If all of these alleles are dominant for the tall gene you will be tall if you are dominant for the short gene you will be short if there is no clear dominance between the two genes you will fall somewhere  in the middle. 
        
             
        
        
        
Answer:
(B). The drug is reabsorbed.
Explanation:
Renal clearance rate determines the excretion of drugs into the urine during excretion. It is used to study the main process associated with a drug's renal excretion. 
When the renal clearance rate is lower than GFR (glomerulus filtration rate), the drug is absorbed in the renal tubules. When the renal clearance rate is higher than GFR, the drug is secreted into the urine. When the renal clearance rate is equal to the GFR, the drug is neither reabsorbed nor secreted. 
As for given drug, renal clearance is 20 ml/min (less than GFR), this drug will reabsorbed. 
Thus, the correct answer is option (B). 
 
        
             
        
        
        
The correct answer is B. Ordovician period
Explanation:
Plants are mainly multicellular organism that depends mainly on photosynthesis to obtain energy, this includes a wide variety of species such as grass, flowering plants, trees, shrubs, etc. Additionally, plants are considered as one f the two major divisions or kingdoms along with animals. In terms of history, it has been determined first land plants appear during the mid-Ordovician period around 470 million ago, although organisms that were the origin of land plants developed in water in previous periods, also by the Devonian period a wide variety of plants have emerged with features that are still part of plants nowadays. Therefore, plant life first appeared on land during the Ordovician period.
