NASA’s Kepler mission found evidence of several potentially habitable exoplanets, raising the possibility that life may have evo

lved independently outside of our solar system. If NASA found a novel lifeform, we would expect it to use energy molecules based on similar principles as lifeforms on Earth. The organism would likely use molecules with _____________ bonds. It might use two separate molecules, one serving as a rapidly utilizable energy currency and another molecule serving as long-term energy storage.
a. high energy.
b. low energy.
c. hydrogen.
d. electrostatic

The microbiology lab was able to isolate one of the organisms from Tara’s blood. Using a Kirby-Bauer test (disk diffusion assay)
Lynna [10]

Answer:

Amoxicillin and Tetracycline

Explanation:

Kirby-Bauer test is used to determine the susceptibility of a bacteria to an antibiotic. The target bacteria is grown on an agar plate. Antibiotic wafers are places on these plates. After some time, the plate is checked. Zone of inhibition (ZOI) is the area around the wafer where no bacteria survived. A reference table is checked for determining the susceptibility of the bacteria to a particular antibiotic. If the value of ZOI is smaller than the value required for susceptibility (S), it means that the bacteria is resistant to that antibiotic.

From the given data, ZOI for Amoxicillin is 25 and S value is ≥29 so the organism in question is resistant to Amoxicillin and Amoxicillin is not an appropriate choice for treatment. Similarly, ZOI for Tetracycline is 18 and S value is ≥19 hence it is not the appropriate choice for treatment.

Kobotan [32]

Answer:

It will bring about a stop to the translation process

Explanation:

The mutant tRNA despite still being charged with Glu, since it's anticodon is mutated and then recognizes and reads the codon UAA which is one of the  stop codons (UAA, UAG and UGA) on the mRNA strand causes the translation process of that particular mRNA strand to stop. And the growing polypeptide chain to be released if any from the ribosomes.

Within which structure of a eukaryotic cells contains DNA
Fiesta28 [93]
The answer is nucleus.

EXPLANATION

Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes.

The nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes.
