The core, or middle, of the Sun is the hottest part. Hot gasses bubble up from the core to the surface of the Sun. When the gasses burn, heat and light are produced.
Answer: a low tide I would say around 5:02a.m.
Explanation:
The best shelling opportunities tend to happen during low tide, where the shells that are normally covered by water are left exposed on the sand.
Answer:
B) Styrofoam is a good insulator.
Explanation:
When talking about thermal energy, or a heat, insulator is a material that doesn't allow heat to pass through easily. On the other hand, a conductor is completely the opposite, it allows, quite successfully, transfer of the heat.
So, regarding ice cream, from these definitions above, we can conclude that insulators will prolong melting time, while, in the conductors, ice cream will melt rather fast.
Looking at the table, we see that Styrofoam had the longest melting time, which makes it quite successful insulator.
Answer: Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template).
Explanation:
