Answer:
High pressure and low temperature, because particles are forced close together and moving slower, so intermolceular forces of attraction increase.
Explanation:
The properties of an ideal gas are explained by the kinetic-molecular theory. An ideal gas assumes there is no intermolecular attraction between the molecules. High pressure would make the particles closer together and interact more, going against the kinetic molecular theory that states there are large spaces between particles and no interactions between particles. Low temperature would make the particles slow which prevents them from overcoming the intermolecular attraction between particles.
Answer: The correct answer is -C) Prevent the embryo from drying out.
The amniotic egg of birds and reptiles is surrounded by an outer, tough, and protective shell, which protects the egg from any damage, predators, pathogens, and drying out.
The tough shell and extra embryonic membranes create a safe environment where an embryo can develop into a whole organism (with different organs like eyes ,ears, brain, kidney, heart).
Thus, option C) is the right answer.
Hello!
The greatest negative impact of a new hydroelectric dam is the changes in the surrounding landscape.
Hydroelectric dams are among the cleanest energy sources, they don't generate waste, pollutants or atmospheric emissions. The negative impact is given by the landscape transformation needed to take advantage of the natural conditions of the dam. They stand out wherever they are, so it is important to consider the aesthetic aspect when building a dam.
Have a nice day!
