50°F is how many °C?
10 |
|
122 |
|
-10 |
|
58 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (50 - 32)\)
\(C° = {5 \over 9} (18)\)
\(C° = {90 \over 9}\)
\(C° = 10\)
Which of these is not a type of fat?
cholesterol |
|
saturated |
|
polyunsaturated |
|
monounsaturated |
Fats come in three types, saturated (meats, shellfish, eggs, milk), monounsaturated (olives, almonds, avocados), and polyunsaturated (vegetable oils).
A compound is a substance containing two or more different chemical elements bound together by what kind of bond?
ionic |
|
molecular |
|
chemical |
|
covalent |
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.
Which of these represents the path of blood flow through the heart?
left atrium → left ventricle → lungs → right atrium → right ventricle |
|
right atrium → right ventricle → lungs → left atrium → left ventricle |
|
right atrium → left ventricle → lungs → left atrium → right ventricle |
|
left atrium → right ventricle → lungs → left atrium → right ventricle |
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.
The heart __________ blood.
creates |
|
filters |
|
deoxygenates |
|
oxygenates |
