Answer:
- <em>You can determine through observation that a mixture is a suspension </em><u>from the fact that particles separate and a solid substance is formed at the bottom of the mixture.</u>
Explanation:
<em>Suspensions</em> are heterogenous mixtures where particles settle when times passes.
The partilces in suspensions are not dissolved (solvated by a solvent). The mixtures where the particles are dissolved are solutions. Then, solutions and supensions are different in that the former have the particles solvated and the latter not.
The particles in a solution are molecules or ions. Such solvated particles in a solution are very small; in comparison,the particles on a suspension are larger. Then, the weight of the particles in a suspension makes that they separate from the liquid and settle down.
The detriment of these advancements to the Earth is that: the growing population is taxing Earth's resources which could lead to the extinction of many species.
<h3>The effect of science and technology.</h3>
Various scientific discoveries and technological advances around the world have led to an exponential increase in Earth's population with no end of the growth in sight.
In conclusion, we can infer and logically deduce that the statement which best describes how these advancements are detrimental to the Earth is that the growing population is taxing Earth's resources and this may likely lead to the extinction of many species of organisms.

When encountering another vessel in darkness, the visible white, red and green lights indicate you are approaching a powerboat head-on.
In this case neither vessels has the right of way. Both boat operators must take early action to stay out of the way for other vessels. The operators must reduce their speed and steer to starboard.
<h2>Further Explanation</h2>
The visible white, red and green lights are all navigation lights with different purposes. However, the four common navigational lights are sidelights, sternlight, Masthead light and all-round white light.
Sidelights are also referred to as combination lights. It is the combination of red and green light and visible to another vessel that approaching head on or from the side. The green light is the boat starboard (right hand side) and the red light is the port side (left) of a vessel.
The sternlight is the white light seen from behind the vessel.
The masthead light is a white light. The white light shines forward to all sides of the vessels. It is on all power driven vessels.
All-round white light is a white light used to combine sternlight and masthead light to form a single white light so that it can boldly be seen by other vessels.
