This statement is false.
The type of fibers in a nerve determines the conduction velocity of the nerve and the factors contributing to the type of fiber is the degree of myelination and the diameter of the fiber; wherein the larger the diameter and the greater degree of myelination, the faster the conduction velocity. What classifies the spinal never whether motor or sensory is its origin in the spinal cord. Nerves originating in the anterior or ventral spinal cord are motor nerves and nerves originating in the posterior or dorsal spinal cord are sensory nerves.
The answer is B. Hairs have different lengths due to variations in the activity of their respective hair follicles. Hair has growth and resting phases. The hairs on the head have longer growth phases compared to those of the eyebrows. Therefore, they grow longer before they start falling out in the resting phase. Those of the eyebrows get to the resting phase quicker hence are shorter
Answer:
Because it plays a major role in regulating body temperature.
Explanation:
The hypothalamus is the heating regulating center of our body which is placed in the hypothalamus. It plays a major role in regulating body temperature, acts as a thermostat and also helps to maintain homeostasis in lots of different ways, for example, by controlling our blood pressure.
When our body cools below the normal temperature it helps to switch up the heat-generating processes and when the body gets overheated it helps to switch off the heat-generating processes.

To describe the process whereby bacteria on the teeth metabolize carbohydrates producing tooth-damaging acids is used the term tooth (or dental) decay. It is a tooth demineralization process that occurs when a tooth is exposed to an acidic environment of pH 5.5 and below. The primary food source for cariogenic (cavity-causing) bacteria is dietary sugars.Suggestion is to b<span>rush and floss promptly after eating so to insure that dental plaque is not present on your teeth.</span>
