Answer:
Gene.
Explanation:
Gene which is responsible for the production of spruceanol in the Peruvian Rosewood plant can be inserted in the host species in order to produce spruceanol  in large quantity so that we can used it as a drug that can cure antimalarial disease. There are certain genes that are responsible for the production of spruceanol in the Peruvian Rosewood plant so if we want to produce this spruceanol in other plants we have to transfer this gene to the host plant.
 
        
             
        
        
        
Answer:
The correct answer is C. differentiation. 
Explanation:
Cell differentiation is a process via which generic embryonic cells are transformed into specialized cells through a process of gene expression. Certain signals from inside and outside our body initiates gene expression. 
Cell differentiation occurs at various stages of development, which causes the size and the shape of the cell to change dramatically. 
Importance of cell differentiation:
- Plays vital role in embryonic development
- Helps in developing organisms throughout their life
 
        
             
        
        
        
Imagine you are surveying a population of a mountain range where the inhabitants live in the valleys with no inhabitants on the large mountains between. If your sample area is the valleys, and you use this to estimate the population across the entire mountain range, <u>you overestimate the actual population size</u>
<u />
Explanation:
- An estimate that turns out to be incorrect will be an overestimate if the estimate exceeded the actual result, and an underestimate if the estimate fell short of the actual result.
- The mean of the sampling distribution of a statistic is sometimes referred to as the expected value of the statistic. Therefore the sample mean is an unbiased estimate of μ. 
- Any given sample mean may underestimate or overestimate μ, but there is no systematic tendency for sample means to either under or overestimate μ.
- Bias is the tendency of a statistic to overestimate or underestimate a parameter. Bias can seep into your results for a slew of reasons including sampling or measurement errors, or unrepresentative samples
