Ques: Answer the following question given this paragraph: The universe contains all the matter and energy that exists and all of space and time. We are always learning more about the universe. In the early 20th century, Edwin Hubble used powerful telescopes to show that some distant specks of light seen through telescopes are actually other galaxies. ( Figure below ) Hubble discovered that the Andromeda Nebula is over 2 million light years away. This is many times farther than the farthest distances we had measured before. He realized that galaxies were collections of millions or billions of stars. Hubble also measured the distances to hundreds of galaxies. Today, we know that the universe contains about a hundred billion galaxies. Q: Who discovered that the andromeda nebula is over 2 million light years away Choices: - richter hubble - smith hubble - mills hubble - edwin hubble A:
Ans: edwin hubble

Answer the following question given this paragraph: affect the rate of diffusion, including concentration gradient, size of the particles that are diffusing, temperature of the system, and so on. In living systems, diffusion of substances into and out of cells is mediated by the plasma membrane. Some materials diffuse readily through the membrane, but others are hindered, and their passage is made possible by specialized proteins, such as channels and transporters. The chemistry of living things occurs in aqueous solutions, and balancing the concentrations of those solutions is an ongoing problem. In living systems, diffusion of some substances would be slow or difficult without membrane proteins that facilitate transport. Q: In living systems, diffusion of substances into and out of cells is mediated by the what membrane? Choices: - gas - fluid - ferment - plasma A:
(A).
plasma
Ques:Answer the following question given this paragraph: Gravity is traditionally defined as a force of attraction between two masses. Weight measures the force of gravity and is expressed in newtons (N). Q: What is the force of attraction between two masses? Choices: - electricity - inertia - momentum - gravity A:

Ans:gravity
Ques: Answer the following question given this paragraph: Antacids are bases that neutralize acids in the digestive tract. Magnesium hydroxide [Mg(OH)2] is one such antacid. It reacts with hydrochloric acid in the stomach according to the following reaction: Mg(OH)2 + 2HCl MgCl2 + 2H2O How many grams of HCl can a 200 mg dose of Mg(OH)2 neutralize?. Q: Antacids are bases that neutralize what in the digestive tract? Choices: - fats - hormones - salts - acids A:
Ans:
