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.
Generally, none. Cirrus cloud is formed of ice particles at high altitudes so there is no precipitation which reaches the ground.
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
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.
The air is essentially warmed when solar energy reaches the ground and is converted to heat. The further you get from the warming effects of the ground the colder the air gets.
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)
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.
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.
Every part of the body requires oxygen in order to maintain metabolism and the circulatory system reaches all body tissues. Arteries are progressively split into smaller and smaller feed vessels (arteriole). At the final stage the blood flows into and out of the capillaries.
