The base pairing for this is usually c-g, a-u, so your answer would be UAC GGA UGC ACC CUG
C. The elements in a group have the same number of valence electrons
<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>

The answer is cerebellum. By processing and interpreting impulses from the motor cortex and brain stem nuclei as well as sensory pathways, the cerebellum provides the precise timing and appropriate patterns of skeletal muscle contraction for smooth coordinated movements and agility needed for daily living. It also plays a poorly understood role in cognition. Cerebellar activity occurs subconsciously (e are not aware of it).
