The solute concentration in blood is equivalent to 0.9% NaCl. In a lab, students viewed a sample of blood with a microscope. Next, several drops of blood were added to three different solutions: 0.09% NaCl,
0.9% NaCl, and
9% NaCl.

1. In the figure below, the panel on the left shows how the RBCs appeared in the blood when viewed at 400× magnification. Label the three other panels by indicating which shows RBCs added to 0.09% NaCl, to 0.9% NaCl, and to 9% NaCl. Below the panels, indicate whether each solution is isotonic, hypertonic, or hypotonic in relation to RBCs.

Which series lists the correct order of steps of binary fission from first to last? sex pilus connects two cells ® plasmid dna is transferred ® complementary dna strands are created ® cells separate live cells bind to degraded cells ® dna is transported across the membrane ® dna is incorporated into recipient's dna virus infects bacterial cell, new viruses are made ® dna is assembled in new virus ® new virus infects another bacterial cell and transfers dna dna is copied ® dna molecules attach to cell membrane ® cell membrane elongates and pinches off ® two identical cells are produced
