Answer:
B) Two different species of bacteria can share DNA, including antibiotic-resistance genes, during conjugation.
Explanation:
Conjugation is a process by which bacteria can exchange their genetic material between them. So through conjugation, the antibiotic-resistant gene coded by plasmid can be transferred through sex pilus to another bacteria.
So due to conjugation two different species of bacteria can share DNA which can include antibiotic-resistant genes. Therefore, through conjugation genetic variation and evolution are favored in bacteria. So due to this reason conjugation is a very important process in bacteria to spread antibiotic-resistant genes.

Answer:
The animal cell will shrink due to loss of water to the external solution
Explanation:
An isotonic solution is that solution which has equal concentration with its external environment. Hence, no net movement of water occurs in an isotonic solution since there is no concentration gradient. Therefore, if an animal cell is placed in an isotonic solution at first, no net movement of water occurs because the intracellular and extracellular concentrations are at equilibrium.
However, if more solutes are added to the solution, it makes the solution HYPERTONIC to the cell i.e greater in concentration. This creates an osmotic gradient and causes water to move out of the animal cell into the solution in accordance to osmotic principles (movement of water from a low concentration of solute to high concentration of solute). This causes the animal cell to likely SHRINK.
