These two types of metals are known as native metals because they are naturally occurring within the Earth's stratosphere. These metals are usually found through mining processes because they are often found mixed with sediments and other soil components. One method of acquiring gold is called gold panning while silver is obtained mixed with silver sulfide and sulfosalt minerals.</span>

Temka [501]

Answer:

Take medicine to destroy the germs.

Avoid contact with other people's bodily fluids.

Eat healthful foods such as fruits and vegetables.

Explanation:

For the spread of disease, there is usually a host who bears the infectious agent, the agent exits through a port of exit from the host, is carried by a mode of transmission, then enters a susceptible second host through a port of entry. To stop transmission, stopping the infectious agent can include;

  1. Stopping the agent from leaving the host through port of exit – e.g quarantine the patient
  2. Curtailing the modes of transmission – e.g killing disease vectors
  3. Protecting the ports of entry in the susceptible second potential host – e.g by improving immunity

Sedbober [7]

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.
