0 |
To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(0) + 32\)
\(F° = 0 + 32 = 32\)

Blood is delivered to bodily tissues through:
capillaries |
|
veins |
|
plasma |
|
arterioles |
The aorta is the body's largest artery and receives blood from the pulmonary vein via the left ventricle. From there, blood is circulated through the rest of the body through smaller arteries called arterioles that branch out from the heart. Finally, blood is delivered to bodily tissues through capillaries.
In a eukaryotic cell, which organelles deal with proteins?
ribosomes |
|
endoplasmic reticulum |
|
Golgi apparatus |
|
all of these deal with proteins |
The nucleus of a eukaryotic cell contains the genetic material of the cell and is surrounded by cytoplasm which contains many organelles. Ribosomes produce proteins, endoplasmic reticulum helps synthesize proteins and fats, and Golgi apparatus prepares proteins for use.
Which of the following indicates the correct reproductive sequence?
none of these are correct |
|
ovum → zygote → fetus |
|
zygote → ovum → fetus |
|
ovum → fetus → zygote |
During intercourse, the penis ejaculates sperm, produced in the testes, into the vagina. Some of the sperm makes their way to the uterus where, if they encounter an egg to fertilize, unite with the ovum to form a fertilized egg or zygote. The zygote then may implant in the uterus and eventually develop into a fetus.
