Plato Answer
Explanation:
Embryonic stem cells are plentiful, and they can create every cell in the human body. Researchers can use these cells to create tissues. They can possibly grow new organs in a lab to treat diseased organs. Adult stem cells are rarer in the human body, and they’re limited in the types of cells they can make.
An embryo can’t grow without its stem cells, so people have ethical concerns about their use. Adults can provide consent to donate their stem cells, so there are fewer ethical issues regarding the use of adult stem cells.
Chimeric mice are generated where approximately 50% of the cells in the animal are genetically MHC class I-deficient. The other 50% are deficient for the herpes virus receptor, HVEM, but do express MHC class I molecules. When these mice are infected with herpesvirus by intraperitoneal injection, a robust virus-specific CD8 T cell response is detected at day 7 post-infection in the spleens of the infected mice.

Catalase is an enzyme used to accelerates chemical reactions in the human body. The performance of an enzyme depends on the pH levels. Catalase performs best at the optimum pH of 7. However, it weakens or denatures at pH levels above 10 though the range may differ on other species.
