To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)
Which of these does not contain oxygenated blood?
pulmonary vein |
|
right atrium |
|
aorta |
|
left 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.
Which of these is important for the body's maintenance, growth, and repair?

stratosphere, troposphere, mesosphere, thermosphere |
|
troposphere, stratosphere, mesosphere, thermosphere |
|
mesosphere, thermosphere, stratosphere, troposphere |
|
thermosphere, mesosphere, stratosphere, troposphere |
The troposphere is the closest layer to Earth, followed by the stratosphere, mesosphere, and finally the thermosphere which borders space.
