<span>Since ages in a population pyramid are represented ranging from youngest at the bottom to oldest at the top, the two graphs aligned side by side typically give the appearance of a pyramid. This is because fewer people in a population live into old age. The BBC notes, however, that it is possible to distinguish different qualities in a population through variations from the standard pyramid shape. For example, an aging population with a low birth rate would look like an upside-down pyramid.</span>
Ecozone is
divergent environment wherein the biotic community, plants, animals and people
and non-biotic community, lithosphere, atmosphere and hydrosphere communicate
and process.

Moreover these
tools aids in detecting ecological changes such as species extinction or
climate disorders due to human activity.</span>
<span>
Hence, Conservationists
that are inclined and supports the proper usage of the natural resources are
able to identify areas and resources that are being misused. They are also able to prevent and report such possible threats to the environment and helps maintain and sustain the ecological system. This will increase the chances to avoiding climate change to a great extent.

I would say that the correct answer from the choices given above is the former option. It would be H2O that exhibits london dispersion forces. It <span> is the weakest intermolecular </span>force<span>. The </span>London dispersion force <span>is a temporary attractive </span>force. Hope this answers the question.
Answer:
The correct answer is - the direction of the points of the V shapes on contour lines.
The contour lines can tell us a lot about the shape of the relief structures on the maps, and of the things that we can also see is the path of the rivers. When the rivers are running through a steeper part, practically their upstream, because they manage to cut and shape the relief structures around them, the contour lines take up a specific V shape. The points of the V are always on the river itself, and they point to the direction from where it is coming from, thus following the points of the V shape can bring us very easily to the upstream of the river.
