I'm pretty sure they would show B. Death rates. Hope this helps!
Answer: is constant
Explanation:
In order to analyze the velocity of the stars within a galaxy, the <u>galaxy rotation curves</u> (developed by the American astronomer Vera Rubin) are used. These graphs are elaborated as a scatter diagram in which the orbital velocity of the stars present in a galaxy is represented on the Y axis and the distance of these stars to the center of the galaxy on the X axis.
Thanks to this diagram, it has been possible to observe a characteristic behavior in the rotation speed of the stars (and gas) present in the galaxies, which differs from the rules of the orbital movement of the planetary systems postulated by Newton and Kepler.
This means that in these galaxy rotation curves it has been observed that the rotation speed of stars and gas is "constant", regardless of the distance to the center of the galaxy. This discrepancy and these results were then used to demonstrate the existence of dark matter in the universe.
It may possibly be a plateau
Answer:
False
Explanation:
The increase in cloud-cover occurs with introduction of larger amounts of aerosols into the atmosphere. The increased amounts of carbon dioxide into the atmosphere will result in an increase of the greenhouse effect. Basically, the carbon dioxide is a greenhouse gas, having properties that enable it to trap the heat into the Earth's atmosphere. By doing so, the carbon dioxide will contribute to warmer atmosphere, thus warmer global climate. The effect of it will be that the Earth will have rise in the temperatures on global scale. The ice sheets will mostly melt, resulting in sea level rise. The rise of the sea levels will mean more ocean water, and less land, which in turn will create climate conditions that will be warm and wet in most of the planet.
B because i was there when my mom at the hospital
