Answer:
The somatic nervous system is associated with activities traditionally thought of as conscious or voluntary. The autonomic nervous system controls our internal organs and glands and is generally considered to be outside the realm of voluntary control.
Diptheria is a serious infection mainly caused by a specific type of bacteria. This diseases is associated to different symptoms.
<h3>What is the causing agent?</h3>
This disease is caused by Corynebacterium diphtheriae, which is a specific type of bacteria. Moreover, this bacteria produces toxins and this is the cause of the symptoms.
<h3>How is it transmitted?</h3>
This can be transmitted through saliva droplets from one infected person to a healthy person. Usually, symptoms appear within 5 days after getting the bacteria.
<h3>What are the symptoms?</h3>
Although this disease has many symptoms, the most important ones are sore throat and gray lining on the throat and nearby areas.
<h3>How to prevent it or treat it?</h3>
Antibiotics and antitoxins are often used, but the best is to prevent it through vaccination.

Answer:
This is an example of "Disruptive selection".
Explanation:
<em>Disruptive selection</em> occurs when <em>selective pressure</em> <em>favor homozygous</em>. In equilibrium, <em>the two alleles might be present or one of them might be lost</em>. If an environment has two extremes, then in these environments, both alleles are presented in homozygous.
The disruptive selection causes an <em>increase</em> in the two types of <em>extreme phenotypes over the intermediate forms</em>. Limits between one extreme and the other are frequently very sharped. Individuals belonging to one phenotype can not live in the same area as individuals belonging to the other phenotype, due to the traits differences between them, competition, or predation.
Populations show two favored extreme phenotypes and a few individuals in the middle. Individuals who survive best are the ones who have traits on the <u>extremes forms</u>. Individuals in <u>the middle</u> are not successful at survival or reproduction.
<em>Color</em> is very important when it comes to <em>camouflage</em>. Dark green caterpillars that live in dark foliage and light green caterpillars that live in light foliage can <em>hide from predators</em> more effectively and will live the longest. Intermediate colored green caterpillars that don't camouflage or blend into either will be eaten more quickly.
Answer:
The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth.
Explanation:
<u>The water cycle is an illustration of how water continuously moves or circulates between the atmosphere and the various parts of the earth. </u>
<em>Evaporation of water from the surface of the earth by the thermal energy from the sun causes water to leave the surface of the earth into the atmosphere. When the atmospheric water vapor (humidity) at the upper strata of the atmosphere becomes high, the vapor condenses to form clouds which later forms precipitation that falls back to the surface of the earth.</em>
The ocean's tidal energy does not cause water to cycle on earth.
Greater portions of the beach begin to appear during ebbing tides, until the maximum amount of beach is visible at low tide. They usually happens twice in a day. Beaches results from wave action by which waves or currents move sand or other loose sediments of which the beach is made as these particles are held in suspension.
