In general, a calculated answer cannot be more precise than the least precise measurement from which it was calculated
The answer is 4.315 billion kilometers so it would be 4.315 x 10 to the 9th power if that is what is meant and Neptune is the eighth planet outward from the sun (the most distant planet from the sun) so it is a tremendous distance from the earth and would be very hard for humans to reach with such a distance.
Answer:
I’m pretty sure it’s all of the above!
Explanation:
1. RNA has ribose sugar instead of deoxyribose
2. RNA is generally single-stranded, instead of double-stranded
3. RNA contains uracil in place of thymine
Answer:
The correct answer will be option B (Interferons).
Explanation:
The innate immune response to viral infection begins with the recognition of pathogen which starts viral host response in organism.
After detection of viral infection cell produces type I interferon's, the protein molecule which interfere with the proliferation of viral cells.
Interferon's provide resistance to viral infection by :
1. Binding to IFN-α/β receptors which activate JAK/STAT pathway.
2. Production of enzymes which leads to the degradation of viral RNA.
3. Induction of ds-RNA-dependent kinase which inactivates the synthesis of proteins.
4. Binding to Natural killer cells which induces lytic activity, killing viral infected cells.
Thus, option B-interferon is the correct answer.
