Answer: The correct answer is -
D. Eukarya has similar evolutionary traits to archaea.
A phylogenetic tree (also known as evolutionary tree) is a diagrammatic representation (in the form of branch diagram) showing the evolutionary relationships among various organisms. It is constructed on the basis of similarities or differences in the genetic or physical characteristics of various species.
In the given phylogenetic tree, archaea domain shows more similarities to the domain eukarya as it has descended after the domain bacteria.
Thus, option D) is the right answer.
A good extraction solvent should have a strong solubilizing capability for the compound of interest, it should be immiscible or only weakly misciblewith the matrix solvent ( the first solution or mixture containing the compound from its natural source, e.g., water/ether. water/ chloroform, etc. If possible the extraction solvent should be non-flammable, non-toxic or of low toxicity, reasonably volatile, and of low eco-impact. Inexpensive and available, of high purity , and shelf stable. If one is determining the compound of interest by UV/Vis spectrophotometry or fluorescence, the solvent should have extremely low absobance or emission at the wavelength of analysis
• high solubility for the solute and low solubility for the carrier liquid.
• density difference vs. the carrier liquid greater than 150 kg/m. ...
• mid-level interfacial tension (5–30 dyne/cm)
• high resistance to thermal degradation.
If the patient weight is 250 lb and the doses are 0.8mg/kg/hour for 12 hours, then the total amount of theophylline needed would be:
250lb * 0.453592kg/lb* 0.8mg/kg/hr * 12hr= <span>1088.6208mg
If the solution contains 800mg of </span>theophylline for 100ml volume, then the volume needed would be: 1088.62 mg / (800mg/100ml)= 136.07ml
Answer:
B) a sequence of three nucleotides
Explanation:
A codon is the sequence of three nucleotides that decide that which particular amino acid would be incorporated in the polypeptide chain. Each codon code for a particular amino acid and responsible for the primary structure of proteins.
During translation the transfer RNA have the anticodon on its one side and amino acid bound to it on its other side. It adds the amino acids to growing polypeptide chain by binding to particular codon on messenger RNA.
Example; AUG is the starting codon for every protein and code for methionine in eukaryotes and anticodon for it is UAC.
