Hello!
A polar molecule is where one of the atoms in a molecule has a slight positive charge, and another has a slight negative charge, due to the unequal sharing of electrons.
Water is one of these molecules - the electrons spend more time around the oxygen atom in the center, and less around the hydrogens, so the hydrogen atoms have a slight positive charge, and the oxygen a slight negative.
Therefore, your answer is B, water has a slight negative and a slight positive charge at opposite poles.
Hope this helps!
A
Because the cells and somethings forms into something new
Answer:
Probably B
Explanation:
They all explain it, honestly, but B sounds the least like an answer they would accept as true. It's also kind of sus that they have 2 different answers about reacting differently to stress, and B is definitely the least likely of the two to be correct. Sorry I couldn't be more helpful, I'm only here because I searched for the answer myself. Good luck.
B or C sound like good answers but I would choose B.
I am pretty sure that the thing which most likely happen to plants if they did not have a waxy outer coating is being revealed by the last option D. They would be harmed by insects and UV radiation. Every plant has to be protected by membrane so that it would be able to deal with drought small invaders and other external forces.
