Simply put, the glass in the analogy traps the sun’s heat inside the greenhouse, warming the interior and not letting the heat escape, just like greenhouse gases (CO2, methane, etc) trap the sun’s heat in the atmosphere, warming the planet and preventing heat from escaping back into space.
Answer:
A population comprises individuals of the same species. A community however is comprised of different populations of several species coexisting in the same area. In short, a population only refers to one species, but a community refers to all living species within a certain area.
Answer:
C) polarity
Explanation:
The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.
- In water molecules hydrogen bonds provides a special dipole - dipole attraction.
- Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine).
- This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge.
- This makes the molecule of water polar.
- By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.
This property of water is polarity of water.
