Hi there!
Because the question here is asking what the safety considerations of a plant in the classroom are, not the care considerations, we can safely narrow this down to one correct solution...
<span>D. Do the plants have any poisonous parts?
</span>
Considering this is the only answer that deals with the safety aspect of plants near children, "D. Do the plants have any poisonous parts?" is the correct answer.
A substance that can be used or prepared for use as food
"resting membrane potential"
Resting potential occurs when membrane potential isn't altered by action potentials. When a membrane is polarised and there's no sinaptic potentials or any other active change of the membrane potential we are before a resting membrane potential.
