B.) Adding a catalyst can increase the rate of reaction
Hope this helps!
The correct answer is option A, that is, a solution with a pH of 1.
pH refers to the unit of measure utilized to articulate the extent of acidity of a substance. The pH scale varies from 0 to 14. A pH of 0 means a very high acid activity, the hydrochloric acid, and nitric acid are very strong with pH values of 0, while the stomach acid exhibits a pH of 1.
Technically, the scale of pH, in reality, depicts the amount of positively charged H+ ions and negatively charged OH- ions in a solution. The pH scale is a logarithmic one, that is, each unit of pH exhibits 10 times as more ions of hydrogens in comparison to the unit above it.
Therefore, in a solution of pH 1, there are 10^9 times more hydrogen ions in comparison to the solution at pH 10.

The primary concern of the scientist in clinical trial is patient safety.
A clinical trial is one of the final stages of any research process according to the requirement. Studies are done to find if the approach of the research and treatment is effective.
Clinical test or trial on human beings is done only after the pre-clinical phase which involves laboratory studies on animals (in vitro) to check the safety and efficiency of the drug. Animals are quite different from humans so human clinical trials are required to be done.
The main aim of clinical trial involves three major things to be considered: if the drug is working, the efficiency of the drug as compared to the currently present drug and most importantly that the drug is safe for human use and the patient is safe after the administration of the drug into the body.
Mitosis occurs in normal cells, or regular cells, while meiosis occurs in sex cells, or gametes. Mitosis takes place everywhere in the body except the sex cells.
