The false statement is: T lymphocytes produce antibody molecules

B lymphocytes produce antibody molecules.

B cells and T cells or lymphocytes are both cells of the adaptive immune system. Progenitor T cells mature (start to express T cell receptors TCRs,  CD4 /CD8 receptors) into T cells in lymphoid organ-thymus. T cell can recognize only those antigens that are presented on antigen-presenting cells, on their surface MHC molecules.

What would happen to an ecosystem if an energy level disappeared? This is meaning in a pyramid.
butalik [34]
This has happened before in Yellow Stone National Park in CA. Removing a species form the Pyramid causes the ecosystem to collapse, as species become over hunted and others are starved. One type of organism could become overpopulated, therefor lack of natural variation.
