A wave will travel only as long as it has energy to carry. The energy makes a wave travel and it will stop traveling as soon as the energy is dissipated.
Answer:
A human community with high population density and low economic status will have the highest birthrates.
Explanation:
A is not correct because usually, these are populations in countries that are transitioning from one political to another political model, and these populations actually tend to decline, mostly because of immigration.
B is not correct because such populations tend to have low birthrates, often even below the bar for simple replacement of the population.
C is not correct because such populations tend to live in very bad conditions, so despite having relatively high birthrates, they stagnate in their growth.
D is correct because such populations have both the numbers needed and also live in more traditional societies, leading to very high birthrates, as can be seen with Nigeria, Ethiopia, Pakistan, Indonesia, etc.

Answer: Polaris
Options:
the moon
the sun
Polaris
Sirius, the dog star
Explanation:
Polaris, also known as the North Star is a star in the Ursa Minor. It is the brightest in this Constellation and when observed over a long period of time, it seems to stays in the same position.
The angle at which Polaris is observed will be similar to the latitude of the observer’s location. For instance if it is seen to be 35 degrees above the horizon, the observer’s location is at a latitude of roughly 35 degrees.
This is due to the closeness of the Polaris to the North Celestial Pole, the axis of the stars in the Northern Sky. As the earth rotates, this creates the appearance that Polaris is stationary.
Titan and makemake
