Chloroplasts.
Always present in almost all plants because they are vital to the process of photosynthesis and primary food production. Onions are not primary producers and do not produce their own food and hence do not require this organelle!
Hope that helps!

It depends if you are taking the class in high school or college. For college doing the experiments is fun but the calculations is not. Also if you are taking it, bring friends.
The correct answer for the first question is liquid bromine. Liquids take the shape of its container but has a fixed volume. The correct answer for the second question is B. Water Vapor. Kinetic energy is a function of temperature, thus molecules at a higher temperature will have high Kinetic energy. In the choices given, water vapor has the highest temperature therefore it has the greatest kinetic energy.
So if you’re looking at a graph, the favored rxn is forward if product amount is higher at equilibrium, or the reverse rxn is favored if the reactant amount is higher at equilibrium.
You can tell through looking at the K value by seeing if it’s a large number, product is favored which means the forward rxn is favored, but if it’s smaller that means he reactant is favored, meaning the reverse rxn is favored.
