Ang guro ay kumakanta ng isang maikling musikal na parirala sa isang walang kinikilingan na pantig, at ang mag-aaral ay kumakanta ng isang iba't ibang mga parirala ng parehong haba.
Answer:
b. flat rotation curves in spiral galaxies
Explanation:
Dark matter accounts for majority of the matter in the universe (about 85%). It is considered to be composed of subatomic particles which are yet to be discovered. Dark matter cannot be observed because it does not emit light that can be detected. Only its gravitational effect is visible.
Astronomers when calculated the mass of the visible matter and tried to account for the observed speed of stars in the galaxy, there was a mismatch. To understand what caused this mismatch, astronomers gave name to the invisible matter as the Dark Matter.
The expected velocity of stars should decrease away from the near the center of the galaxy but a constant velocity of stars was observed that is a relatively flat rotation curve was obtained.
Thus, flat rotation curves in spiral galaxies in an evidence of Dark Matter.
Fertility rates and resources are connected because in areas where there are scarce resources and high fertility rates there will be problems in the ability to provide for the members of this hypothetical society. Therefore, individuals or animals could potentially live shorter and less healthy lives because of the lack of proper resources such as food, water, healthcare, or education.
