Answer:Normally because the flu virus doesn't last very long because your body is very used to the flu.
Transfer RNA (tRNA) is a type of ribonucleic acid. It brings amino acids to the ribosomes and mRNA for the structural organization into proteins. Thus, option D is correct.
tRNA is an adaptor molecule that decodes the mRNA sequences in the form of amino acids through the ribosomes. It is involved in the translation process of complex protein synthesis.
tRNA transports the amino acids (codons) to the ribosomes to join them with their complementary (anti-codon) sequence for the polypeptide assembly.
Therefore, the tRNA carries amino acids for polypeptide formation.

Read the excerpt about two men trying to bury a dead soldier right in the middle of a battle.
"Yes," said Lean. The two privates stood waiting, bent over their implements. "I suppose," said Lean, "it would be better if we laid him in ourselves."
"Yes," said the adjutant. Then apparently remembering that he had made Lean search the body, he stooped with great fortitude and took hold of the dead officer's clothing. Lean joined him. Both were particular that their fingers should not feel the corpse. They tugged away; the corpse lifted, heaved, toppled, flopped into the grave, and the two officers, straightening, looked again at each other—they were always looking at each other. They sighed with relief.
The adjutant said, "I suppose we should—we should say something. Do you know the service, Tim?"
"They don't read the service until the grave is filled in," said Lean, pressing his lips to an academic expression.
"Don't they?" said the adjutant, shocked that he had made the mistake.
"Oh, well," he cried, suddenly, "let us—let us say something—while he can hear us."
"All right," said Lean. "Do you know the service?"
"I can't remember a line of it," said the adjutant.
Lean was extremely dubious. "I can repeat two lines, but—"
"Well, do it," said the adjutant. "Go as far as you can. That's better than nothing. And the beasts have got our range exactly."
Lean looked at his two men. "Attention," he barked. The privates came to attention with a click, looking much aggrieved. The adjutant lowered his helmet to his knee. Lean, bareheaded, he stood over the grave. The Rostina sharpshooters fired briskly.

B. Lampreys
C. Birds
D. Frogs and toads
Would it be A.?
it would be the lampreys because they do have a backbone
Answer:
B. It is a single-stranded molecule
Explanation:
Unlike DNA, RNA is usually single stranded and can folds back upon itself forming a secondary structure known as Hairpin loop. DNA is double stranded. In this way both RNA and DNA become more stable and are prevented from forming bonds with other molecules.
