Answer:
To store genetic information to pass on to other living organisms.
Answer:
A polygenic trait can be described as a physical trait which is influenced by more than one gene.
The three types of selection for a polygenic trait are:
1) Directional Selection: In a directional selection, one of the phenotype is favored in an ecosystem. As a result of this favoring, the allelic frequency changes and shifts in favor of this particular trait.
2) Stabilizing selection: It is a type of natural selection in which the intermediate trait is favored. The population carries a middle trait in abundance.
3) Disruptive Selection: Disruptive trait is a type of natural selection in which the traits on the extreme sides are favored. The intermediate traits are less favored.
Coronary artery disease is when plaque in arteries causes blood to not flow correctly or as smoothly as possible. Therefore, a heart attack can occur if blood can't flow.
New media, smaller equipment, and instant sharing, are all part of the new environmentalist tools for visual documentation.
<h3>What is Visual documentation?</h3>
This is defined as the process in which knowledge or information is managed and organized in a visual manner.
This however employs the use of equipment such as projectors and internet sharing devices to ensure that the information is disseminated to a large number of people.

Answer:
water
Explanation:
Water puts out fire by creating a barrier between the fuel source and the oxygen source (it also has a cooling effect which has to do with the energy required to convert liquid water into water vapor). It does this because it is a completely, 100% oxidized material. It simply cannot oxidize any further so it will not “burn”. This smothers the fire. The same thing would happen if you used the ashes that remained after a completely spent fire. Or, as I mentioned before, CO2.
