3. jack is using plastic beads to model water molecules in each state of water. how shoule she the beads to represent water mole

just olya [345]

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.

DNA is produced in the mitochondria. genetic material that directs the cell. responsible for directing the activities of the cel

Artist 52 [7]

No that is just, no just no. DNA is copied through cell reproduction where a cell splits to create more (growing for multi called organisms and asexual reproduction for single celled organisms) The mitochondria is an organelle that is the "power house" of the cell, the "digestive system".
