Answer: d. guns happened to be in the room.
Explanation:
The weapon effect theory is a theory of social psychology. It suggests that mere presence of weapon or its picture can lead to aggressive behavior or may produce shock in human participants.
This theory was demonstrated by the Leonard Berkowitz and Anthony LePage in 1967. These researchers selected 100 male university students for one laboratory session.
These were randomly assigned to receive one or seven shocks. These shocks generated by the weapon those were kept on the laboratory and were related to belong to one of the peer. This will may generate mental shock among the students.
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.
The toxins would enter through the Xylem.
