Answer:
C. Diffusion and no energy needed.
Explanation:
A - Passive transport doesn't require energy.
B - Osmosis would be if the 25% H2O went into the 82%
D - Active transport doesn't apply because molecules aren't moving across into a higher concentration.
Diffusion is when parts of the 82% go into the 25%.
Answer:
prevents secretion of upper air passage
Explanation:
to prevent foods and drinks from falling down the airway which is called aspiration and may lead to pneumonia
Structurally, DNA and RNA are nearly identical. As mentioned earlier, however, there are three fundamental differences that account for the very different functions of the two molecules. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine.
DNA has sequences that mRNA finds the pair for (ex. DNA says AGC, RNA says UCG)
with that, they only come in 3 nucleotide increments.
