Which of blood component fights infection?
plasma |
|
white blood cells |
|
platelets |
|
red blood cells |
Blood is created in bone marrow and is made up of cells suspended in liquid plasma. Red blood cells carry oxygen, white blood cells fight infection, and platelets are cell fragments that allow blood to clot.
212°F is how many °C?
0 |
|
100 |
|
\(135 {5 \over 9}\) |
|
-100 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (212 - 32)\)
\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)
\(C° = {900 \over 9}\)
\(C° = 100\)
What is a major difference between the somatic and autonomic nervous systems?
one controls voluntary activity, one controls involuntary activity |
|
each belongs to a different nervous system |
|
one is inherited, the other is learned |
|
one controls thinking, the other controls feeling |
Both are part of the peripheral nervous system. The somatic nervous system sends sensory information to the central nervous system and controls voluntary actions while the autonomic nervous system regulates involuntary activity in the heart, stomach, and intestines.
The ovum and oviduct are part of which bodily system?
digestive |
|
reproductive |
|
nervous |
|
circulatory |
Approximately every 28 days during female ovulation an egg (ovum) is released from one of the ovaries and travels through the oviduct (fallopian tube) and into the uterus. At the same time, the endometrial lining of the uterus becomes prepared for implantation.

To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)
