Answer: As the mass of star increases, the temperature and luminosity also increases.
Explanation:
This can be described in what happens in main sequence star( example, the Sun), which is powered by fusion of hydrogen into helium in its core. Main sequence star exhibit a common characteristic which is hydrostatic equilibrium. This means,the inward force of gravity, which tends to compress the star, is balanced by the outward force due to the pressure. Thus when an extra mass such as hydrogen is added to its core, there will be increase in mass which leads to a higher compression. This in turn will lead to central density and temperature. As the temperature increases, fusion of gases occurs faster resulting to a much higher luminosity. I hope this helps, thanks.

Answer:
Genetic engineers can transfer a specific piece of DNA or genes from one organism to another organism. This is usually done by adapting recombinant DNA methods. In this approach, a gene of interest is cut with restriction enzymes and then inserted and ligated to the host genetic material. This host could be a bacteria or eukaryote.
Example: Biotechnologists can produce insulin by inserting human gene in <em>E. coli</em>. The bacteria replicate its genome fast and produce protein (insulin) which can be extracted and applied to the person who is diabetic. Similar methods have been used for other purposes.
