The answer is C where the star is found in the sky. If a star is moving toward us, its spectroscopy will be observed at shorter wavelengths, this is called "blueshifted". If the star is moving away from us, the lines will appear in longer wavelengths, and that's called "redshifted".
Sorry for a late response, but I hope this helped.

1) Bees swarm to find shelter and increase their chances of survival.
Explanation:
Options are
1) Bees swarm to find shelter and increase their chances of survival.
2) The worker bees have an increase of survival due to their ability to find a mate.
Bees swarm to find new shelter because the population is high in the hive so they find a new place for themselves.

Answer:
climate, geology, abstraction, poverty
Explanation:
Climate: lack of precipitation can lead to a lack of water. That is why is rain is important.
Geology can also be a factor in the availability of water. When water goes under the ground, rocks let the water enter through and make a water depot that is saved underground.
Regular cleaning of the water. Even though in some places there is enough water because of the pollution, it can’t be used.
Abstraction: it is important to have a limit when using water. If the amount of water for use is smaller than the water we get through precipitation, the quantity will be balanced.
When the country is rich, it can provide regular water inspection, while in poor countries this can be a big problem.
