The respiratory and circulatory systems are similar in that they:
add carbon dioxide |
|
transport nutrients |
|
deoxygenate blood |
|
transport oxygen |
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.
As part of digestion, the liver produces bile which breaks down:
protein |
|
sugars |
|
starches |
|
fat |
The liver produces bile which emulsifies (separates) fat.
Which of the following members of the food chain are most alike?
scavengers and decomposers |
|
herbivores and autotrophs |
|
producers and tertiary consumers |
|
primary consumers and omnivores |
Like decomposers, scavengers also break down the dead bodies of plants and animals into simple nutrients. The difference is that scavengers operate on much larger refuse and dead animals (carrion). Decomposers then consume the much smaller particles left over by the scavengers.
Respiration is the process by which __________ absorb oxygen and eliminate carbon dioxide.
diaphragms |
|
bronchioles |
|
blood cells |
|
capillaries |
The respiratory system manages respiration which is the process by which blood cells absorb oxygen and eliminate carbon dioxide.
What kind of weather front is likely to create clouds and storms?
temperate front |
|
warm front |
|
cold front |
|
stationary front |
A warm front is the boundary between warm and cool (or cold) air when the warm air is replacing the cold air. Warm air at the surface pushes above the cool air mass creating clouds and storms.
