<span>Smooth muscles and cardiac muscles
are both classified as involuntary. Both muscles are continuously working which
means it does not stop even when a person is at rest. As smooth muscles surround most of the walls
of the major organs of the body, cardiac muscle however can only be found in
the heart. They are not both innervated singularly which implies that the
impulses that travels through these paths are passed from a cell to another
cell. Both are automatically controlled by endocrine and nervous systems and
produce rhythmic contractions as impulses are innervated. </span>
Answer: The human body is designed to experience stress and react to it. Stress can be positive ("eustress") -- such as a getting a job promotion or being given greater responsibilities -- keeping us alert and ready to avoid danger.

Answer:
The correct answer is the primary response.
Explanation:
Immune response to an antigen can be categorized as a primary response or the secondary response, Primary response takes place as a result of first time exposure to the antigen. Naïve B-cell and T-cell are the cells of the primary response action. The lag phase is generally four to seven days however in some cases it can be weeks or months.
The primary response is slower in comparison or the secondary response. IgM is main and produced first in the primary response. Lymph nodes and spleen are sites for the primary response.
Thus, the correct answer is the primary response.
