Answer:
Lumen
Explanation:
Luminous flux is known as the power of light perceived by the eye. The SI unit of luminous flux is known as lumen where one lumen is the amount of luminous flux emitted from a directional unit point source through a unit solid angle.
Since the human eye can see only the visible spectrum of light which is perceived in the form of luminous flux and thus lumen.
Thus, the lumen is the correct answer.
The answer is; codon, codon, anticodon
There are about 64 different combinations of three nucleotide bases into codons. The combinations, however, only code for 20 amino acids hence some codons are redundant. When the mRNA forms a scaffolding with the ribosome, the tRNA with the right anticodon (sequence complementary to the codon on the mRNA) to the codon on the A site of the ribosome, leaves its amino acid at the site of chain elongation (P-site) and exits at the E-site.
The nurse should first note the amount, color as well as the
odor of the amniotic fluid.
Explanation
<span>When a patient’s membrane ruptures
spontaneously, the nurse should start by checking the consistency, odor, as
well as the volume of the amniotic fluid. For this case, there are minimal
chances of cord prolapse because the fatal head is already engaged and at 0
station. If the fatal head is not yet engaged, the nurse should start by
checking for cord prelapse if the membrane ruptures spontaneously. </span>
Answer:
Gen lac z: codifies the enzyme β-galactosidase, that hydrolyzes lactose in glucose and galactose.
The other two structural genes are lacy, which is a permease that helps to transfer lactose into the cell. Finally, lacA is a trans-acetylase.
Also, the operon counts with a promoter, that is the region recognized by the RNA polymerase. An Operator region, that is recognized by the LacI repressor, and the repressor gen lacL.
