In high altitude, the oxygen pressure will be much lower that makes the gas exchange rate is lower and decrease the oxygen delivery to <span>the tissue.</span> To counter this, the mouse will increase its depth of ventilation so there is more air inside the lungs for every inspiration.
Answer: c. The Earth’s surface is responsible for a small fraction of heat radiation to space.
Explanation:
In later ages the large amount of sun's energy is reflected back by the terrestrial surface back to the space. But now due to the abundance of large concentration of greenhouse gases in the atmosphere is responsible for the absorption of thermal energy from sunlight by these gases causing the atmosphere to be hot. This is the reason of global warming. Now only small fraction of heat is radiated back to the space.
Most of it follows its cycle, going back to the atmosphere.
The image below, shows you how the nitrogen cycle is.
