The plant used cellular respiration to release energy for use by the cell.
The nucleus controls everything in the cell
In order to find the total number of combinations, multiply 2*3*2*4*3 to get 72. So 72 total combinations can be made.
Hope this helps!
T killer cell or Cytotoxic T cells are the cells in animals that are used to destroy bacteria and viruses after combining with lysosomes.
<u>Explanation</u>:
The T cells kills the bacteria and virus. The T cells can easily identify the pathogen when combined with the lysosomes. The activated T cells releases a material called perforin. This substance gets into the walls of the affected cell and punctures its walls. Due to hole in the walls, there happens discharge of fluid and electrolytes, which leads to the death of the cell. The substance secreted is the cytolytic proteins from the lysosome which helps in destruction of the infected cells.
Option D. They cause disease.
