Answer:
b. mRNA from DNA
Explanation:
Transcription is the process of synthesis of RNA using a DNA template strand. The process of transcription occurs inside the nucleus in eukaryotes as their DNA is present in the nucleus.
The process includes unwinding of DNA double helix to expose the DNA template strand. The enzyme RNA polymerase binds to the specific start sites on the DNA template strand and starts making its RNA copy.
The newly formed RNA undergoes modification in eukaryotes before serving as a template for protein synthesis. However, in prokaryotes, the process of transcription and translation can occur simultaneously.
Answer: high-energy primary cosmic-ray particles interact with air nuclei high in the atmosphere, initiating a cascade of secondary interactions that ultimately yield a shower of electrons, and photons that reach ground level.

Explanation:
Can you think of a solid that can flow?
You use one twice a day! Toothpaste is a solid that can flow. Is the asthenosphere made of toothpaste? Only if the
toothpaste is ultramafic in composition, and then it would only be able to flow if it were really, really hot. Still the
toothpaste analogy gives you a good image of how the asthenosphere might behave if you squeezed it!
Lithosphere
The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid
solid. The lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid. The lithosphere is
about 100 kilometers thick. How are crust and lithosphere different from each other?
C it wont start a tornado, or a storm surge
