White Blood Cells (WBC), produced by the stem cells found in the bone marrow, manufacture antibodies used to counter the effects of the antigens.
The White Blood Cells are known to provide immunity to the body against foreign bodies like bacteria, virus, proteins, etc. The lymphocyte cells, namely, the B-cells and T-cells are the two key cells that make antibodies for various antigens and kill or lyse the foreign body by recognising the antibiotic marker attach to them.

<span>As per excerpts, Water covers 75 percent of Earth and 97 percent of water on Earth is salt water, meaning only 3 percent of water is available as fresh water. Based on this information, 3% of 75% of the water on earth is available as fresh water or 2.25%. Since most of the water is said to be locked up in solid glaciers and polar ice caps, the amount of water on the planet that is available for animals to drink is lesser than 2.25% so the best approximation is 1 percent.</span>
<span>All cells have the same DNA. They are different because different genes have been locked up and only some of them are expressed. The process began in the embryonic stage, when stem cells are turned into different types of cells by turning off some of the genes. Scientists have been looking for ways to reverse the process, meaning turning specialized cells back into stem cells. Some success has been reported using different methods. The latest one uses a weak acid to stress the cells.</span>
