A non-specific immune response (also called immunity) is antigen-independent while a<span> specific immune response is antigen-dependent. The examples of the non-specific immunity are fever, phagocytosis by macrophages, skin and mucus. The example of the specific immune response is c</span>ytotoxic T-cells able to recognize antigens on infected cells and kill them before the infection could spread. So, the first line of defence is the non-specific immune response. However, if pathogens pass that line of defence, the specific immune response activates.
<span>The correct answer is B. The law of conservation of energy. The energy was in them and when the reaction came the energy was changed form, which is what the law of conservation of energy is, energy can't be created or destroyed, just like matter, it just changes form.</span>
The answer is a. basalt. Gabbro rocks are more related to basalt in terms of chemical characteristics. They are both igneous rocks but basalt is an extrusive rock that cools quickly while gabbro is intrusive and cools slowly. So, basalt rocks are fine-grained while gabbro are coars-grained.
