Options for the question are not given. They are as follows:
a. arg or lys
b. ala
c. thr
d. leu or ser
e. Only termination codons
Answer:
d. leu or ser
Explanation:
Four codons code for proline amino acid. These are CCT, CCC, CCA, and CCG. Hydroxylamine causes C to change into T or G to change into A.
If first position is changed in each codon:
CCT = TCT (UCU)
CCC = TCC (UCC)
CCA = TCA (UCA)
CCG = TCG (UCG)
These codons produce Serine amino acid.
If second position is changed in each codon:
CCT = CTT (CUU)
CCC = CTC (CUC)
CCA = CTA (CUA)
CCG = CTG (CUG)
These codons produce Leucine amino acid.
Hence, out of the given options, option d. leu or ser is correct.
Photograph the impression, frame the impression, pour the cast, remove the cast is the one that describes the correct order of steps to be taken when casting a soil impression.

Answer: When the oxygen-rich blood gets to the cells, the cells receive the oxygen and release the carbon dioxide. The blood with less oxygen and a lot of carbon dioxide returns to the heart. Then the heart returns this blood to the lungs where carbon dioxide is released and oxygen is received.
Explanation:
Decomposers are living organisms that breaks down other living and non-living things into smaller parts.
Decomposers can recycle dead plants and animals into chemical nutrients such as carbon and nitrogen that are released back into the soil, air and water as food for living plants and animals.
