Which of these does not contain oxygenated blood?
left ventricle |
|
right atrium |
|
aorta |
|
pulmonary vein |
To provide oxygen to the body, blood flows through the heart in a path formed by the right atrium → right ventricle → lungs → left atrium → left ventricle → body. When blood enters the right side of the heart it is deoxygenated. It enters the left side of the heart oxygenated after traveling to the lungs.
Convert 0C° to F°.

To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(0) + 32\)
\(F° = 0 + 32 = 32\)
A compound is a substance containing two or more different chemical elements bound together by what kind of bond?
covalent |
|
chemical |
|
ionic |
|
molecular |
A compound is a substance containing two or more different chemical elements bound together by a chemical bond. In covalent compounds, electrons are shared between atoms. In ionic compounds, one atom borrows an electron from another atom resulting in two ions (electrically charged atoms) of opposite polarities that then become bonded electrostatically.
A transition zone between two air masses is called:
thunderstorm |
|
fog |
|
boundary |
|
front |
An air mass is a large body of air that has similar moisture (density) and temperature characteristics. A front is a transition zone between two air masses.
An element in the physical state of __________ maintains a constant volume but their shape depends upon the shape of their container.
gas |
|
plasma |
|
liquid |
|
solid |
In the liquid state, molecules flow freely around each other and exist at a higher temperature range than the same substance in a solid state. Liquids maintain a constant volume but their shape depends upon the shape of their container.
