50°F is how many °C?
58 |
|
-10 |
|
10 |
|
122 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (50 - 32)\)
\(C° = {5 \over 9} (18)\)
\(C° = {90 \over 9}\)
\(C° = 10\)
The rows of the Periodic Table of the Elements are called:
groups |
|
shells |
|
families |
|
periods |
The rows of the Periodic Table are called periods and contain elements that have the same number of electron shells ordered from lower to higher atomic number.
In the classification of life, bacteria, archaea and eukaryota are which of the following?
classes |
|
domains |
|
kingdoms |
|
species |
The broadest classification of life splits all organisms into three groups called domains. The three domains of life are bacteria, archaea and eukaryota.
Traits represented by genes may be which of the following?
recessive |
|
dominant |
|
all of these |
|
expressed |
The traits represented by genes are inherited independently of each other (one from the male and one from the female gamete) and a trait can be dominant or recessive. A dominant trait will be expressed when paired with a recessive trait while two copies of a recessive trait (one from each parent) must be present for the recessive trait to be expressed.
Blood is delivered to bodily tissues through:
plasma |
|
capillaries |
|
veins |
|
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.
