The answer is B. Hydrogen Bonds
I believe you use the pH scale with comparing acids and bases.
The correct answer is option B, that is, the sympathetic system prepares the body for stress and activity and the parasympathetic system prepares the body for rest.
Both the parasympathetic and sympathetic nervous system are the components of the autonomic nervous system that works obligatorily. The sympathetic nervous system holds the key in controlling the body at the time of stress and injury, it is generally regarded as fight or flight. It contracts the muscles of the heart in order to enhance the rate of the heart.
On the other hand, the parasympathetic nervous system is responsible to monitor the function of the body when it is at rest. It assists in sustaining the homeostasis in the body. It relaxes the muscles of the heart in order to reduce the rate of the heart.
Answer:
These are the four tissues: connective tissue, epithelial tissue, muscle tissue, and nervous tissue.
Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body). Muscle tissue includes striated (also called voluntary) muscles that move the skeleton, and smooth muscle, such as the muscles that surround the stomach. Nerve tissue is made up of nerve cells (neurons) and is used to carry "messages" to and from various parts of the body.
