<span>T cells are a class of leukocytes that play a large role in the secondary immune response. "T" is the abbreviation of the thymus, the organ in which their development ends.
They are responsible for cellular immunity: cells infected with a virus, for example, or cancer cells are known to be foreign to the body (that is, distinct from the cells that T cells have learned to tolerate when maturation) is destroyed by a complex mechanism.
T-cell needs the antigen MHC I molecule (present in all the nucleated cells), to be activated.
While The B cell needs the antigen presented by MHC II molecule present in antigen presenting cells.
</span>T-cells bind 1 type of antigen (which is an endogenous antigen, as opposed to B cell which bind exogenous antigen) which must be presented by another cell.<span>

This is true. During the Mesozoic era, many new species of reptiles were made. The Mesozoic era is also sometimes called the Age of the Dinosaurs.
Hope this helps!
Carbon dioxide, water, and ATP. I just got done with this unit in science. Because glucose + oxygen = Carbon dioxide, water, and ATP.
one parent has to be homozygous dominant, and the other parent has to be homozygous recessive.
Adenosine Triphosphate is a compound used by the cell to store energy. Together with NADP, ATP is responsible for carbon dioxide reduction. Carbon dioxide is said to be reduced when it loses oxygen, reacts with hydrogen or gains electrons. Carbon dioxide becomes part of Glycerate 3-phosphate.
