In a eukaryotic cell, which organelles deal with proteins?
all of these deal with proteins |
|
endoplasmic reticulum |
|
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.
What part of the nervous system controls simple reflexes?
autonomic |
|
medulla |
|
cerebrum |
|
spinal cord |

212°F is how many °C?
-100 |
|
100 |
|
\(135 {5 \over 9}\) |
|
0 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (212 - 32)\)
\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)
\(C° = {900 \over 9}\)
\(C° = 100\)
Water freezing or boiling is an example of which of the following?
heating |
|
cooling |
|
phase transition |
|
sublimation |
A substance undergoes a phase transition when it moves from one state of matter to another, for example, when water freezes or boils.
The most diverse kindgom of life is which of the following?
fungi |
|
protists |
|
animals |
|
plants |
Below domain, life is classified into six kingdoms: plants, animals, archaebacteria, eubacteria, and fungi. The last kingdom, protists, include all microscopic organisms that are not bacteria, animals, plants or fungi. (Archaebacteria and eubacteria are sometimes combined into a single kingdom, monera.)
