Answer:

A) Stars have the same brightness, color, and mass.

Explanation:

Stars are celestial bodies that have their own light and differ from each other in terms of brightness, color and mass. They are actually giant spheres composed of gases that produce nuclear reactions, but thanks to gravity, they can stay alive (without exploding) for trillions of years. In our galaxy - the Milky Way - there are over a hundred billion stars. The sun is one of them.

There are red, yellow, white and blue stars. Stars emit lights of different colors due to their temperature. The red ones, with about 3000º C, are the ones with the lowest temperature; while at around 40000º C, the blue ones have the highest temperature.

Which of the following is not required for osmosis to occur?
Damm [24]

Answer:

Cellular energy

Explanation:

Osmosis is the movement of water from a less concentrated to more concentrated solution across a semi-permeable membrane. Cellular energy is not required in osmosis because it is a passive process. Osmosis is technically more or less the selective diffusion of water molecules across a membrane  that selectively locks out other larger molecule like ions. Water will, therefore, move from the solution where there are more water molecules to the solution with fewer water molecules.
