Nothing else but ASAP thanks

Transcribed Image Text:68. Polypeptides are synthesized from amino acid building blocks. The condensation reaction
between two amino acids to form a dipeptide involves the loss of
A) a water molecule.
B) an amino group.
C) a carbon atom.
D) a carboxylic acid group.
69. The variations in the physical characteristics between different proteins are influenced by the
overall amino acid compositions, but even more important is the unique amino acid
A) number.
B) sequence.
C) bond.
D) orientation.
E) size.
70. Protein folding can be studied using a solution of purified protein and a denaturant (urea), a
solvent that interferes with noncovalent interactions. Which of the following is observed after
the denaturant is removed (e.g., by dialysis) from the protein solution?
A) The polypeptide returns to its original conformation.
B) The polypeptide remains denatured.
C) The polypeptide forms solid aggregates and precipitates out of solution.
D) The polypeptide adopts a new, stable conformation.
E) None of the above
71. Why is SDS recommended to use in a denaturing polyacrylamide gel for protein analysis?
A) SDS may disrupt membrane bilayers if used in a extraction buffer.
B) SDS will denature the proteins (i.e., disrupting quaternary and tertiary structure of the
proteins), thus linearizing them and facilitating their migration through the gel.
C) SDS will confer a uniform negative charge to all proteins in the sample, which then will
migrate towards the anode according to their size.
D) All of the above
E) None of the above

After surgery to remove the tumor, his oncologist recommended 40 Gy of external X-ray radiation, split into 22 doses, to kill any remaining cancer cells. He is here for his 22nd and final treatment. Karen is taking part in a research study aimed at determining whether X-ray irradiation can ease the symptoms of advanced arthritis.

The dispatcher asks the patient a series of questions from a set of cards, and then transmits the call to your agency's data terminal and over the EMS radio system. 1. What are some of the roles of EMS dispatch? 2. How do the concepts of encoding and decoding apply to the call to this point? Based on the information received from the dispatcher, your agency sends your ALS ambulance, and you quickly arrive at a neatly kept suburban household. You are let into the home by the patient's husband who leads you to his 70-year-old wife sitting in the family room. The patient is able to speak but slurs words slightly.
