The broadest classification of life splits all organisms into three groups called domains. The three domains of life are bacteria, archaea and eukaryota.

To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)
The respiratory and circulatory systems are similar in that they:
transport oxygen |
|
transport nutrients |
|
deoxygenate blood |
|
add carbon dioxide |
Like the respiratory system, the circulatory system serves to transport oxygen throughout the body while removing carbon dioxide. In addition, the circulatory system transports nutrients from the digestive system.
What is a major difference between the somatic and autonomic nervous systems?
one controls voluntary activity, one controls involuntary activity |
|
one is inherited, the other is learned |
|
each belongs to a different nervous system |
|
one controls thinking, the other controls feeling |
Both are part of the peripheral nervous system. The somatic nervous system sends sensory information to the central nervous system and controls voluntary actions while the autonomic nervous system regulates involuntary activity in the heart, stomach, and intestines.
When compared to eukaryotic cells, prokaryotic cells are:
similarly complex |
|
less complex |
|
none of these |
|
more complex |
Cells are classified into one of two groups based on whether or not they have a nucleus. Eukaryotic cells have a nucleus, prokaryotic cells do not have a nucleus and therefore have a less complex structure than eukaryotic cells.
