significant digits are certain digits that give detail in a number
ex. in the number 400 it is the 4 because it tells you how many hundreds are in the number, in the number 49.92 it would be all of them because they all help understand the number
Do you get it?
Carbon dioxide is a colorless and non-flammable gas at normal temperature and pressure. Although much less abundant than nitrogen and oxygen in Earth's atmosphere, carbon dioxide is an important constituent of our planet's air. A molecule of carbon dioxide (CO2) is made up of one carbon atom and two oxygen atoms. Carbon dioxide is an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas.

These are just a few of many, but all abiotic factors are not living. Hence A-Biotic
Biotic means living, so when you put the ''a'' prefix it means the opposite of living.
Answer:
A. Repeats of "Alanine-Arginine"
B. Repeats of "Tyrosine-Isoleucine"
C. Repeats of Aspartic acid
Explanation:
A. The synthetic RNA with GC repeats would have repeats to two codons: GCG and CGC which in turn code for alanine and arginine amino acids respectively. Hence, its polypeptide would have repeats of "Alanine-Arginine"
RNA: GCG CGC GCG CGC GCG CGC
Alanine-Arginine-Alanine-Arginine-Alanine-Arginine-Alanine-Arginine

B. The synthetic RNA with UA repeats would have repeats to two codons: UAU and AUA which in turn code for tyrosine and Isoleucine amino acids respectively. Hence, its polypeptide would have repeats of "Tyrosine-Isoleucine"
RNA: UAU AUA UAU AUA UAU AUA
Tyrosine-Isoleucine-Tyrosine-Isoleucine-Tyrosine-Isoleucine-Tyrosine-Isoleucine
C. The synthetic RNA with GAC repeats would code for polypeptide of aspartic acid only as GAC codes for aspartic acid.
RNA: GAC GAC GAC GAC GAC GAC
Aspartic acid-Aspartic acid-Aspartic acid-Aspartic acid-Aspartic acid-Aspartic acid
I would say the alveoli. They are tiny air pockets in the lungs: this is where the diffusion of oxygen and carbon dioxide occurs.
Hope this helps! x
