B. Transgenics
C. Bioreaction
D. Recombination
The correct answer is option B. "Transgenics"
Transgenics is a term used to describe the artificial insertion of one or more DNA sequences to an organism that would normally not have it. In this example, the term transgenics applies to the cows that serve as hosts for the production of the spider silk.

I think the question is full in any missing percentage what is water .
Answer
To decrease the PH of a neutral solution add to it an acidic substance such as lemon juice.
Explanation
The p H (potential of hydrogen) is the level of an aqueous solution which tells us how acidic or basic a substance/solution is based on it hydrogen ion concentration. The higher the concentration of hydrogen ions, the lower the p H. In distillated water that has a p H of 7(neutral), you can increase the p H of the water by adding an alkaline substance such as baking powder.
