Molecules and atoms that are outputs from a chemical reaction are known as which of the following?
results |
|
reactants |
|
products |
|
side effects |
During a chemical reaction molecules and atoms (reactants) are rearranged into new combinations that result in new kinds of atoms or molecules (products).
In cell biology, the primary difference between anaerobic and aerobic respiration is that aerobic respiration requires:
oxygen |
|
mitochondria |
|
water |
|
sugar |
Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.
An air mass is a large body of air that has which of the following characteristics?
similar density |
|
all of these |
|
similar moisture |
|
similar temperature |
An air mass is a large body of air that has similar moisture (density) and temperature characteristics. A front is a transition zone between two air masses.
The respiratory and circulatory systems are similar in that they:
transport oxygen |
|
transport nutrients |
|
add carbon dioxide |
|
deoxygenate blood |
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.
Cellular fermentation takes place:
in plant cells |
|
anaerobically |
|
in the presence of oxygen |
|
aerobically |
If no oxygen is present, cellular respiration is anaerobic and will result in fermentation where either lactic acid or alcohol is used instead of oxygen.
