In the classification of life, bacteria, archaea and eukaryota are which of the following?
species |
|
kingdoms |
|
classes |
|
domains |
The broadest classification of life splits all organisms into three groups called domains. The three domains of life are bacteria, archaea and eukaryota.
In the pancreas, lipase converts fat to:
amino acids |
|
glycerol and fatty acids |
|
simple sugars |
|
complex carbohydrates |
The acids produced by the pancreas contain several enzymes that aid in digestion. Lipase converts fat to glycerol and fatty acids. Pancreatic amylase breaks down complex carbohydrates into simple sugars. Trypsin converts polypeptides (the building blocks of protein) into amino acids.
Antigens are found on the outside of which blood cells?
platelets |
|
white |
|
red |
|
plasma |
Blood is categorized into four different types (A, B, AB, and O) based on the type of antigens found on the outside of the red blood cells. Additionally, each type can be negative or positive based on whether or not the cells have an antigen called the Rh factor.
A large naturally occurring community of flora and fauna occupying a major habitat is:
a population |
|
a biome |
|
a community |
|
a food chain |
A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).
-40°F is how many °C?
-8 |
|
\({40 \over 9}\) |
|
-40 |
|
\(-{40 \over 9}\) |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (-40 - 32)\)
\(C° = {5 \over 9} (-72) = {{-72 \times 5} \over 9}\)
\(C° = {-360 \over 9}\)
\(C° = -40\)
