Ques: Q: An rna codon reading guu encodes for what? Read this paragraph and choose the correct option from the provided answers: This chart shows the genetic code used by all organisms. For example, an RNA codon reading GUU would encode for a valine (Val) according to this chart. Start at the center for the first base of the three base codon, and work your way out. Notice that more than one codon may encode for a single amino acid. For example, glycine (Gly) is encoded by a GGG, GGA, GGC, and GGU. Notice there are 64 codons. Of the 64 codons, three are stop codons. Choices: - glycine - carbon - arginine - valine A:
Ans: valine

Ques: Q: The major component of a solution is called what? Read this paragraph and choose the correct option from the provided answers: The major component of a solution is called the solvent. The minor component of a solution is called the solute. By major and minor we mean whichever component has the greater presence by mass or by moles. Sometimes this becomes confusing, especially with substances with very different molar masses. However, here we will confine the discussion to solutions for which the major component and the minor component are obvious. Solutions exist for every possible phase of the solute and the solvent. Salt water, for example, is a solution of solid NaCl in liquid water; soda water is a solution of gaseous CO2 in liquid water, while air is a solution of a gaseous solute (O2) in a gaseous solvent (N2). In all cases, however, the overall phase of the solution is the same phase as the solvent. Choices: - solute - mixture - water - solvent A:
Ans: solvent

Ques: Q: Where is most of the cell's dna contained? Read this paragraph and choose the correct option from the provided answers: Although most of a cell's DNA is contained in the cell nucleus, mitochondria have their own DNA. Mitochondria also have the machinery to manufacture their own RNAs and proteins. The human mitochondrial DNA sequence has 16,569 base pairs encoding 37 total genes: 22 tRNA genes, 2 rRNA genes, and 13 peptide genes. The 13 mitochondrial peptides in humans are integrated into the inner mitochondrial membrane, along with proteins encoded by nuclear genes. Choices: - vacuole - epidermis - cell membrane - nucleus A:
Ans: nucleus

Ques: Q: Emphysema is a chronic disease caused by the breakdown of the what tissue? Read this paragraph and choose the correct option from the provided answers: Emphysema is a chronic lung disease caused by the breakdown of the lung tissue. Symptoms of emphysema include shortness of breath, especially during exercise, and chronic cough, usually due to cigarette smoking, and wheezing, especially during expiration. Damage to the alveoli ( Figure below ), is not curable. Smoking is the leading cause of emphysema. Choices: - heart - liver - brain - lung A:
Ans:
lung
