Answer:
A
Explanation:
The Sun, Moon, and planets appear to move across the sky much like the stars. Because of the Earth's rotation, everything in the sky seems to move together, turning once around us every 24 hours. ... Likewise, every point on the celestial equator is exactly overhead from some point on the Earth's equator.The Sun, Moon, and planets appear to move across the sky much like the stars. Because of the Earth's rotation, everything in the sky seems to move together, turning once around us every 24 hours.
The answer is B (speed up chemical reactions).
Answer: Replication
Explanation: When the cell is preparing to divide it will <u>replicate</u> its DNA so that both of the daughter cells will have a complete set of the DNA. It's like a book of instructions and the cell has to perfectly replicate it so that when it splits into two both of the new cells will have a perfectly made copy of it! Hope this helps :)
During DNA Replication, the DNA molecule unzips itself so that there are two free strands of DNA. Both of those strands then create new complementary strands of DNA. Thus every subsequent generation of DNA uses one of the parent cell's strand of DNA as a template, which is why DNA replication is said to be semi-conservative. Hope this helped!
The question that could be investigated through scientific research is B. Does a newly synthesized chemical reduce bacteria? The answer is B. Because the other questions aren’t science questions. They are bias.
