Jack should arrange the beads close together and slide past each other to represent water molecules in a liquid.
<h3>How are the molecules of water arranged when water is in its liquid phase?</h3>
- Each water molecule contains two atoms of hydrogen and one atom of oxygen, arranged such that one side of the molecule (nearest the hydrogens) is positively charged while the other side (nearest the oxygen) is negatively charged.
- They’re arranged randomly, and in random motion.
- In fact, they’re not even keeping the same hydrogen atoms, as they are constantly popping off and reforming on the nanosecond time scale.

Answer:A
Explanation it is well thought out and it the most logical
Answer:
Cryopreservation
Plant Vitrification Solution 2 (PVS2) and Plant Vitrification Solution 3 (PVS3)
Explanation:
Cryo-preservation or cryo-conservation is defined as the process of preservation of all cellular and structural elements such as cells, organelles, tissues, organs, or any other biological constructs by cooling to very low temperatures.
Two commonly used solutions in plants for this purpose are Plant Vitrification Solution 2 (PVS2) and Plant Vitrification Solution 3 (PVS3). Plant Vitrification Solution 2 (PVS2) is consists of, w/v, 0.4 M sucrose, 30% glycerol, 15% DMSO and 15% ethylene glycol and Plant Vitrification Solution 3 (PVS3) comprising, w/v, 50% sucrose and 50% glycerol.
Hence, the correct answer is "Cryopreservation
Plant Vitrification Solution 2 (PVS2) and Plant Vitrification Solution 3 (PVS3) "
Because they both have a nucleus but both of them do not have a cell wall
