Why are the freezing melting and boiling points lower on high altitude?
Heat is only energy. In areas of low pressure, such as high altitudes, "heat" particles, which are charged electrons, escape more quickly. As more "heat" (electrons) escapes more quickly, things freeze more quickly. As far as I know melting and boiling points are higher, not lower in high altitudes.
How does exercise increase minute ventilation?
Minute ventilation is the amount of oxygen inspired by the body in a minute. It is increased by long term exercise because over time the body becomes more adept at bringing more oxygen in to the lungs to be taken to the working muscles. As tidal volume and breathing rate increases the minute ventilation will increase as more breathes will be needed to be taken to meet the high demand for oxygen. A healthy young person will take around 35-45 breathes per minute where as an athlete may take around 60-70 breaths per minute.
Do people native to higher or lower altitudes produce more or less blood cells than those people native to altitudes at sea level?
When a person is at a higher altitude, their red blood cells get bigger, so they can carry more oxygen. You don't have to be a native for this to happen.
Where does water evaporate more quickly?
The best condition for water to evaporate is in a temperate controlled room at 74 degreesFahrenheit. also add a sunroof and proper air ventilation
Why do some species living at high latitudes and high altitudes tend to be ecological generalists while tose living in the tropics tend to be ecological specialists?
there are less resources available at high altitudes, so they have to generalize because they need to eat whatever they can to stay alive. On the other hand, those living in the tropics have a wide variety of other species living with it and a whole lot more resources. Therefore, they can specialize to eat one thing (helps with keeping them alive and helps with sharing the resources with everyone else if they only take one thing)
Why do jet airplanes fly at high altitudes?
Jet airplanes fly at high altitudes because it is more fuel efficient. Flying at higher altitudes uses less fuel than flying at lower altitudes.
Does freezing feel colder in high altitudes?
No, though higher altitudes will be at the freezing point more often.
What characteristic of the atmosphere changes with altitude?
The temperature and level of oxygen. High altitudes sometimes have more snow and low altitudes are usually drier.
Why does sound travel more slowly in the air at high altitudes than low altitudes?
The air is thicker at lower altitudes, we know that sound travels much better when it can move through solid mass. As you climb, the air starts to get thinner. It becomes much more difficult to do anything at high altitudes, including keeping a plane aloft, keeping warm, and of course projecting sound.
What is the adaptation for loading and unloading oxygen at high altitudes?
At higher altitudes, where there is less oxygen available, the body makes more red blood cells, hemoglobin, to carry oxygen more efficiently.
How much are NEC projectors?
NEC's multimedia projectors cost from $310 to about $5,000. They also make cinema projectors which are even more expensive.
Why is it more difficult to breath at the top of a mountain?
This is due to the thinness of the atmosphere at high altitudes (e.g. the top of a mountain). The thinness is caused by the loss of molecules to space due to the slight lessening of gravity's pull at high altitudes.
What is the mechanism by which the body makes more red blood cells when the person moves to high altitudes?
Aclimatization.
How many educator now a days are using overhead projector?
As high tech electronics are becoming more popular these days, the use of overhead projectors have deteriorated. More people are using "Smart" boards or "E" boards. The use of overhead projectors are slim to none.
Why are ultraviolet rays more dangerous on high mountains?
At high altitudes, where the air and cloud cover are thinner, it allows more damaging UV rays to get through the atmosphere.
Why is there more clouds at higher altitudes?
high altitudes indicate cold temperatures so then that means that water vapor condenses at cooler temperatures and when water vapor condenses then it creates clouds
Do people from high altitudes have trouble breathing at sea level?
No, from being used to breathing at high altitudes, their body has created more capillaries which allow them to use oxygen more efficiently. The only reaction they would have from being at sea level is a lower respiration rate, or needing to breath less.
