Answer:
B cells are activated when their B cell receptor (BCR) binds to either soluble or membrane bound antigen. This activates the BCR to form microclusters and trigger downstream signalling cascades.
Explanation:
No, If anything it would cause a balance in the carbon system because if humans breathe out carbon dioxide and plants absorb that carbon dioxide there wouldn't be any imbalance.
Forces acting on an object that combine and form a net force of zero are balanced forces. As shown in the figure on the opposite page, balanced forces do not change the motion of an object. Forces acting on an object that combine and form a net force that is not zero are unbalanced forces.
If a solution process is exothermic, the energy required for dissolving the solute compare with the energy released is that, the energy requiredis less than the energy released. When we sayexothermic, heat is evolved. On the other hand,when heat is absorbed, this is called endothermic.
