Answer:
Evolution
Explanation:
Evolution – change over time. It is the process by which modern organisms have descended from ancient organisms. Current scientific facts, observations and hypotheses all combine to create current evolutionary theory – which is a well-supported, testable explanation of the biological diversity on Earth.
Answer:
C. Hydrogen bonds
Explanation:
Anticodon refers to the set of three nucleotides present in tRNA. The anticodon is complementary to the codon of mRNA. The nucleotide bases of anticodon and mRNA codons are paired by hydrogen bonds.
Here, the adenine of anticodon makes the hydrogen bond with the uracil base of codon while the guanine base of anticodon forms the hydrogen bond with the cytosine base of the codon.
There is a specific tRNA with an anticodon complementary to the mRNA codon for each amino acid. For example, the tRNA for phenylalanine has an anticodon 3' AAG 5' and binds to the complementary mRNA codon base via hydrogen bonds.
C. bacteria because those are bad cells that cause infections.
