Which of these foods should a person with high cholesterol avoid?
eggs |
|
avocados |
|
vegetable oils |
|

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 part of the nervous system is responsible for controlling involuntary actions like breathing, swallowing, and heartbeat?
medulla |
|
spinal cord |
|
cerebrum |
|
cerebellum |
Part of the brainstem, the medulla is the connection between the brain and the spinal cord. It controls involuntary actions like breathing, swallowing, and heartbeat.
Reproductive haploids are also known as:
diploids |
|
ovum |
|
gametes |
|
sperm |
Reproductive (haploid) cells known as gametes have half as many (23) pairs of chromosomes as normal (diploid) cells. When the male gamete (sperm) combines with the female gamete (ovum) through meiosis to form a zygote, each gamete supplies half the chromosomes needed to form the normal diploid cells.

|

|
stratus clouds |
Cumulus clouds are large, puffy, mid-altitude clouds with a flat base and a rounded top. These clouds grow upward and can develop into a cumulonimbus or thunderstorm cloud.
