The primary means for transmitting messages between the brain and the rest of the body is the ______.

Nesterboy [21]

Answer:

The primary means for transmitting messages between the brain and the rest of the body is the spinal cord.

Explanation:

The spinal cord is the main pathway of the nervous system. The impulses are transmitted to the brain through bundles of ascending nerve fibers, while the descending fibers transmit impulses in the opposite direction. Signals are transported to and from different parts of the body along the fibers of the pair of spinal nerves, which form intersections with the spinal cord through their dorsal and ventral roots; the sensory and motor fibers converge in the gray matter of the medulla.

Answer:

The thyroid gland increase in size.

Explanation:

Iodine plays an important role in the generation of thyroid hormones and is mainly found in the soil in coastal areas and in seawater. In the developing nations, the individuals who live at high elevations or inland are generally deficient in iodine and can develop a condition known as goiters.

In the condition, the thyroid gland increases in size in an attempt to get more iodine. However, in the countries where iodine is added routinely to foods and table salt, the lack of dietary iodine is not the typical reason of goiters.

Answer:

The interaction between the sloths and the leaves they eat is an example of a predator-prey relationship. In this example, sloths are herbivores that acquire their nutrients and energy from the plants they eat. The colors of coral snakes provide these animals with mimicry to avoid predation. Specifically, their coloration helps them advertise their toxicity. The interaction between the hosts and the ticks that live on them can be characterized as parasitism, because one species feeds on the other.

Explanation:

Predator-prey relationships are those in which a specie feeds on another specie. The sloth is the predator that feeds on the leaves which are its prey. Herbivores feed on plants. Therefore, the sloth are rightly classified as herbivores.

Coral snakes are brightly colored with red, yellow, and black patches that warn potential predators of their toxicity. Ticks living on hosts are parasitic because the ticks feed on their host.
