The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
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.

The human pedigree generally represents a symbolic illustration of how a particular trait is inherited across generations in a particular family. It shows the relationship between the members of a family and how the trait is passed down each generation either in a silent or expressive form.
Individuals within a human pedigree are represented with symbols and <u>those affected by the trait in question are completely shaded</u>. <u>Those carrying the trait in silent form are half-shaded while those that do not have traces of the trait at all are left completely unshaded.</u>
