oxygen
temperature
Heat Stroke- is a response to heat characterized by extremely high body temperature and disturbance of the sweating mechanism. it is a immediate life threatening emergency.
Advantage of open circulatory system: * requires less engergy for distribution * it need less need of oxygen * blood pressure remain low Disadvantages for open circulatory system: * not very effective, because fluid is pumbed under low pressure, so it corculates more slowly than in closed circulatory system Advantage of closed circulatory system * Operates much higher blood pressure * blood pumped under high pressure so it reaches destination quickly * immune response are much Stronger, helping body fight infection Disadvantage: * stronger heart is required, more energy to maintain * is complex but more powerful
when the temperature reaches the dew point.
To enable the gases inside the balloon to expand which they do when the balloon reaches high altitudes. At this point the balloon becomes much larger.
Stratosphere Commercial airliners typically cruise at altitudes of 9-12 km (30,000-39,000 ft) in temperate latitudes (in the lower reaches of the stratosphere)
Differences in air temperatures at different altitudes are primarily caused by the way the atmosphere absorbs and retains heat from the sun. As you increase in altitude, the air pressure decreases, causing the air to expand and cool. This results in lower temperatures at higher altitudes compared to lower altitudes.
Proctor tells her that he will cut his hands off before he reaches for her again.
All-or-none response means that things have to reach a certain threshold, a certain level before they happen. If it reaches that threshold, it becomes a cascading response that increases in size. If it fails to reach the threshold, well, nothing happens.
At higher altitudes, the boiling point of water is lower due to decreased atmospheric pressure. This means that water reaches a lower temperature when boiled, resulting in a less hot cup of tea than at sea level.
Actually water evaporates , i.e , it becomes a gas and rises up. At high altitudes , the temperature is quite low , so it again condenses , and that's how it reaches the sky.
