Answer:
B. Base pairing occurs within an RNA molecule to give RNA the three-dimensional shape needed for specific functions.
Explanation:
Ribonucleic acid, known as RNA, is a type of nucleic acid found in living systems. In opposition to the other type of nucleic acid (DNA), RNA is a short single stranded molecule. Both DNA and RNA are made of nucleotides, composed of a phosphate group, nitrogenous bases and a pentose sugar.
The presence of ribose sugar and Uracil base in RNA instead of deoxyribose sugar and thymine base respectively structurally differentiates the molecule from DNA. However, base pairing occurs within the RNA molecule to form the three-dimensional shape of the RNA, which is key to the specificity of its function.
Answer: The percent error is 3.88%
Explanation:
Percent error = [(Actual bones - Counted bones)/ Actual bones] X 100%
= [(206 - 198)/206] X 100%
= [8/206] X 100%
= 3.88%
Thus, Carl's percent error is 3.88%
Answer:
I think it's " P waves from earthquakes can travel through both solids and liquids so they tell us what is inside the earth. "
Explanation:
New moon: we see darkness (aka nothing)
Waxing crescent moon: we see a sliver of light that indicates the crescent (during this time, the moon moves eastward away from the sun)
First quarter moon: when half the moon's face is illuminated.
Gibbous moon: when more than half the moon is illuminated, we call this a gibbous
Full moon: we see the whole round moon, lit up.
Waning gibbous moon: when the moon becomes thinner, but is still lit up for over half of its shape.
Third quarter moon: this is where the moon shows the other half of itself (that we didn't see in the 1st quarter) while the other half is dark.
Waning crescent moon: when the moon is a thin crescent, traveling down into the darkness of the full moon.
This process takes about a month (29.53 days).
