Explain how Co2 is able to control fires?<br><img src="https://tex.z-dn.net/?f=co2" id="TexFormula1" title="co2" alt="co2" align
Alborosie

Carbon dioxide is heavier than oxygen gas. It therefore displaces the oxygen gas around a flame. Without oxygen, the combustion reaction will stop and the flame will be put out.

Further Explanation:

In order for a combustion reaction to happen, three components must be present: fuel, oxygen, and heat to cause ignition. When one of these three is removed, the combustion reaction will stop.

CO2 fire extinguishers use the difference in mass of the CO2 and oxygen molecules to stop the fire. Since CO2 is heavier, it will displace any oxygen molecules that are around the flame. When this happens, the supply of the oxygen will be limited or cut-off and the fire will eventually be put out because of the lack of oxygen. This ability to displace oxygen is also what makes using CO2 as fire extinguisher quite dangerous for the user since it pushes away the oxygen that is needed for respiration.

Other ways to put out fire include spraying liquids that absorb the heat to avoid spreading the fire further or spraying substances that coat the fuel (flammable materials) to avoid contact with oxygen gas which can lead to further combustion.

Which of the following might occur if people fail to conserve water? a. Increased sewage system failures b. Increased numbers of
pishuonlain [190]

If people fail to conserve water then there will be increased sewage system failures.

Water conservation entails keeping water from assets like rain, wastewater, and snow melting using it for family and agricultural activities. Increased sewage gadget disasters can not preserve water as this water comes from toilets, sinks, bathing, laundry, etc. That is wastewater and contaminants ought to be eliminated from it to make it appropriate for reuse. Failure of sewage gadget will now no longer be capable of taking away pollution from this water and therefore this can not be reused.

<h3>What is a water sewage system?</h3>

These are 3 types of water sewage systems:

  1. separate system
  2. combined system
  3. partially separate system

Hence concluded that if people fail to conserve water then there will be  Increased sewage system failures.

Answer:

A. Survive environmental changes.

Explanation:

Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.

A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).

Deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms.

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

The characteristics which are consistent with the concept of natural selection includes;

I. More offspring are produced than can survive in an environment (overproduction of offspring). This ultimately implies that, the more offsprings that are reproduced by the parent organism, the more likely are they to survive.

II. There is genetic variation within populations. This simply means that there is a better chance of having good or beneficial traits being passed from the parent organism to her offsprings.

III. Organisms with beneficial variations are more likely to survive and reproduce, as well as passing on their genes to subsequent generations.

Hence, a population of living organisms with a large gene pool (gene diversification) is more favorably disposed to survive environmental changes than a species population having a small gene pool.

In conclusion, the higher the genetic makeup of a living organism, the higher are its chances of surviving environmental changes in the ecosystem.
