Answer:
Two important measures of a population are population size, the number of individuals, and population density, the number of individuals per unit area or volume. Ecologists estimate the size and density of populations using quadrats and the mark-recapture method.

Answer:
It will end up on an orbit that is farther from the Sun
Explanation:
Total energy must be conserved, so if one asteroid loses energy and moves to a closer orbit, the other has to gain energy and move to a more distant orbit.
Answer:
The cause was the command type of economy and the result was famine and millions of deaths.
Explanation:
The communist governments in East Asia, like all communist countries, had command economies. This meant that everything in the economy is planned and regulated by the government. This was also the case with agriculture, where government officials were making a plan on how much and what should be produced. The plans were often made in the manner that it should be produced as much as society needs.
Because agriculture is heavily dependent on weather conditions, as well as the impact of pests, even the slightest disturbance meant that there won't be enough food, and if it was a bigger disturbance then a big portion of the population would have experienced a famine. This has happened on numerous occasions, with the small amount of food being forcefully transported to the cities, while the rural population that produced it was left without anything for eating. The end result has been tens of millions of deaths because of starvation, based on terrible politics.
Answer:
The asteroid's path is a trajectory path which could be called an orbit.
Explanation:
When an object moves along a curved path or circular path, a centripetal force is required to sustain it in the path. The forms atrajectory path in which the object continues to move when no external forces are applied.
The Sun applies a gravitational force (centripetal force) on the asteroid after it got bumped from the spot on Jupiter. This force applied constrained it to move in the long oval shape every 15 years continuously. The long oval shape is in a form of trajectory path which could be called an orbit. Therefore, we can say that the asteroid orbits around the Sun and completes the path every 15 years.
