Answer:
Astronomers can use telescopes to look at very distant galaxies. This is how they see what the Universe looked like a long time ago. This is because the light from distant parts of the Universe takes a very long time to reach us. From these observations, it seems the physical laws and constants of the Universe have not changed.
Physicists are currently unsure if anything existed before the Big Bang. They are also unsure whether the size of the Universe is infinite.
Answer:
the answer is A, cellular reproduction.
Explanation:
because cellular reproduction is a process by which cells duplicate their contents and then divide to yield multiple cells with similar, if not duplicate, contents, basically reforming itself again.
After cycle 4, a disease arrived that affected brown mice only was most likely included in its simulation.
<h3>What is Disease?</h3>
This is defined as any harmful deviation from the normal structural or functional state of an organism.
This usually leads to death and the table shows a steady decline from cycle 4 which means a disease most likely arrived which affected brown mice only.

Answer: DNA and RNA are both examples of nucleic acids
They consist of a strand of nucleotides with a phosphate group, a 5′ sugar and a nitrogenous base.
Extra info: DNA and RNA molecules are polymers. DNA is double stranded, whereas RNA is single stranded.
The nucleotides of DNA can pair together by base pairing, creating a strand that is complementary to its pair
Various types of RNA exist which have roles in protein synthesis as well as regulation of cellular programmes by fine-tuning gene expression.
The answer is; opioids
These painkillers relieve pain by competing with neurotransmitters in binding neurotransmitter receptors in the synapse. However, they don’t induce an impulse hence block the receptors from neurotransmitters. This working principle, however, is also problematic because it causes slow breathing because the drugs calm nerve activity even that which controls your breathing.
