Answer:
C
Explanation:
These type of questions leave a great deal to be desired. There is no mention of which way Hubble used and manipulated data. He studied the variations in light to determine his conclusions.
Nor is there any mention of what Lomonosov did to come to the conclusion that conservation of mass is a constant.
We don't know what was done to get the results. Hubble was studying the universe; the conclusions made by Lomonosov depended on lab equipment that was very delicate (I'm assuming). I doubt he manipulated variables. He measured what he got.
I think the answer is C, but the question has so many assumptions that it is hard to know what answer to pick.
Answer:
Obsidian is an igneous rock that forms when molten rock material cools so rapidly that atoms are unable to arrange themselves into a crystalline structure. It is an amorphous material known as a "mineraloid." The result is a volcanic glass with a smooth uniform texture that breaks with a conchoidal fracture (see photo).

Answer:
True.
Explanation:
Antibiotics may be defined as the chemicals that are required to stop the growth and kill the other living organism. These antibiotics have been developed against bacteria, fungi and microorganisms.
The excess use of the antibiotics leads to the development of the resistant strain against that particular antibiotic. People should not overuse or misuse the antibiotics as they may become resistant and antibiotics will not effect the pathogens of that individual organism.
Thus, the correct answer is option (a).
