A division of your immune system called cell mediated immunity is charged with stopping viral infections. The main actors of that are called cytotoxic T cells who, when they encounter a cell that is displaying viral antigens on its surface, binds to the cell and releases toxic substances called perforins and granzymes that destroy and digest the viral infected cell.
The geologic time scale is organized into eras, and the eras are organized into periods.
Answer:
At the end of meiosis 1, double number of chromosomes are present in each cell.
Explanation:
Meiosis is a type of cell division in which a single parent cell is divided into four daughter cells. In meiosis 1, a single cell is divided into two daughter cells having double number of chromosomes. After that meiosis 2 occurs in which these two daughter cells again divided into four daughter cells having half number of chromosome. This type of cell division only occurs in the sex cells.
