Answer

Brief Explanations:

  • For the first question, a hypertonic solution has a higher solute concentration. Since solution A has 1.5% saline and solution B has 0.5% saline, solution A is hypertonic to solution B.
  • For the second question, streptomycin is effective against gram - negative bacteria.
  • For the third question, active transport uses carrier proteins and energy to move molecules against their concentration gradient.

Answer:

B. Solution A is hypertonic to solution B. B. negative D. Active transport
