Answer:
In relative dating, fossils are dated according to the depth at which they were buried. ... While in the absolute dating, isotopes of carbon are used for dating fossils. The absolute dating is more precise than relative dating because it tells the exact age of the fossils.
Explanation:
Polar. Water is given the term “universal solvent”. Being polar, it allows it to create hydrogen bonds with many different molecules
It is difficult to regulate liquid waste (effluents) leaving a factory, as there is no means of containment and remediation is difficult.
- A. liquid waste (effluents) leaving a factory
<h3>How are liquid effluents generated in industries?</h3>
Industrial Effluents, on the other hand, will have their generation linked to the typology and the industrial process, in this way, all the water that was not lost through evaporation, infiltration and that ends up left over from the production process, that is, that is not incorporated into the final product, ends up becoming effluent.
<h3>How is waste generated by industries disposed of?</h3>
The most used treatments for this type of waste are the aerobic and anaerobic process, which use biological agents, such as
- bacteria
- algae
- and protozoa
to degrade the organic matter of the effluents.
With this information, we can conclude that Industrial waste is a wide variety of leftovers, waste or remains originating from manufacturing activities.

Answer:
The correct answer is bottleneck effect.
Explanation:
The phenomenon of bottleneck effect takes place when some natural events like a tsunami or an earthquake result in the destruction of the majority of the population and leave behind some to survive. Due to the bottleneck affect the genetic diversity within the population gets reduced drastically as the majority of the population gets perished, this results in the eradication of some of the genes from the population, while the left genes are passed onto the next progenies.
The bottleneck effect results in the generation of the new population as the leftover individuals further inbreed and give rise to a new population comprising the leftover genes. It is not necessary that the left genes passing on to the next generation are better than the one, which got eliminated, as the left genes have got selected by chance. Thus, it can be concluded that the given case is an illustration of the bottleneck effect.
Answer;
When only white and red lights are visible, you are approaching the port side of a powerboat and thus you should give way to your starboard side.
Explanation;
-The red and green lights are called sidelights (or combination lights) because they are visible to another vessel approaching from the side or head-on. The red light indicates a vessel's port (left) side; the green indicates a vessel's starboard (right) side.
-When only a white light is visible, one may be overtaking another vessel. Give way to either side. Additionally, when only a red light is visible, you are approaching the port side of a sailboat.
