Which of these is not a function of bone in the human skeletal system?
protect bodily organs |
|
store minerals |
|
produce blood cells |
|
store vitamins |
Hard bones provide primary support for the endoskeleton while more flexible cartilage is found at the end of all bones, at the joints, and in the nose and ears. In addition to providing support and protecting bodily organs, bones also produce blood cells and store minerals like calcium.

In a eukaryotic cell, which organelles deal with proteins?
endoplasmic reticulum |
|
all of these deal with proteins |
|
ribosomes |
|
Golgi apparatus |
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.
-40°F is how many °C?
-8 |
|
-40 |
|
\(-{40 \over 9}\) |
|
\({40 \over 9}\) |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (-40 - 32)\)
\(C° = {5 \over 9} (-72) = {{-72 \times 5} \over 9}\)
\(C° = {-360 \over 9}\)
\(C° = -40\)
Water coming to a boil on a stove, ice melting, and steam from a cup of coffee are all examples of which of the following?

|
