answer: Noroviruses, unlike the Ebola virus, are extremely hardy, able to travel through the air and stay for days on surfaces where they can infect new people. "Noroviruses are perhaps the perfect human pathogen," one CDC scientist declared in a scientific review.
Answer:
UUU
Explanation:
A codon is a sequence of three nucleotide bases in a mRNA molecule that specifies an amino acid. During the process of translation, the mRNA strand is read in a group of three nucleotides at a time. A type of RNA called transfer RNA (tRNA) posseses in its structure another group of triplet nucleotides called ANTICODON, which is complementary to the sequence of bases in the mRNA codon.
The tRNA anticodon recognizes and binds to the particular mRNA codon it is complementary to in order to carry the amino acid it specifies to the growing polypeptide chain In this case, the mRNA codon reads AAA. This means that the anticodon on the tRNA that will bind to this codon is UUU.
From the choices, I think the correct answer would be option 4. The proper procedure for delivering prepared hot food off-site would be maintain hot food temperatures above 135 degrees Fahrenheit or 57 degrees Celsius. At this temperature, you would be able to deliver the food still warm while making sure that it is cooked enough, not under or over cooked. This temperature is a fair enough level to be able to ensure that the delivered food is not cold and would still be like as if it was cooked recently. Also, along with maintaining this temperature, it would be best to deliver it very fast to the customer.
ATP is not produced directly by the ETC but instead via the proton gradient generated during electron transport through the ETC.
