How can I bring oxygen to a How can I bring oxygen to a
fish bowl without a filter or
oxygen pills or pump because
my fish always goes to the top
to take oxygen help!!!!
It is a goldfish

how about you just tank care of your fish properly....and get it a real tank with a filter...your fish has no air edit: so it gets even better...a gold fish...a common gold fish gets over 12in each and need a min of 75 gallons and another 20-30 for each fish after that....and they put out about 2X the waste as most fish there size....please get this fish a proper tank or give to someone who will |

What was the probable role of A. Cellular respiration, which
depends on oxygen
availability, provided
abundant energy to the first
life forms.
B. Oxygen promoted the
formation of complex organic
molecules through physical
processes.
C. Oxygen gas tends to disrupt
organic molecules, so its
absence promoted the formation
and stability of complex
organic molecules on the early
Earth.
D. Abundant atmospheric oxygen
would have created an ozone
layer, which blocked out
ultraviolet light and thereby
protected the earliest life
forms.
E. The lack of oxygen forced
organisms to develop cellular
respiration.

C. Oxygen gas tends to disrupt organic molecules, so its absence promoted the formation and stability of complex organic molecules on the early Earth. That's the response your teacher wants anyway, although it's dumb to say that "absence" of something "promotes" something else. It would have been better to say that presence of oxygen gas would have prevented formation of complex organic molecules. |

what's the difference between i have read that the qantas
flight 30 incident was the
first aviation incident
involving an oxygen canister
or bottle. however, in 1996 in
the US, valuejet flight 592
plunged into the everglades
due to a fire caused by an
oxygen generating cylinder.
what's the difference between
these two oxygen tanks?
thanks to all of the answers
so far, this is great
information to me, i'm a bit
of a commercial aircraft fan.
how will i ever choose which
one's best?! lol....:)

A bottle holds pressurized gas, just as you would see a mechanic take an airbottle out to a car/plane/trailer and fill up the tire with compressed air. The o2 generators utilize a chemical reaction that is initiated when the 3 chemicals are mixed... which occurs when you pull down on the mask. The resultant chemical reaction generates about 15-20 minutes of o2 for your mask. The problem with Valujet 592 was the generators when they fire off, exotherm up to around 500 degrees F and they were improperly rigged/packed/shipped... so the chain reaction created a fire that incredibly intense and brought down the aircraft. |

What are oxygen tanks doing in That hole in the side of the
Quantas jet last week was
caused by an exploding oxygen
tank that was stored in the
cargo hold of the plane. Why
are oxygen tanks in the cargo
hold in the first place?

When you flew, do you remember this little safety speech about "in case of cabin depressurization, and oxygen mask would fall from the ceiling" bit? There are two ways to have oxygen in such conditions: 1- though oxygen generators (canisters filled with chemicals that react together and release pure oxygen when activated) 2- oxygen tanks Regulations require that pilots have a more reliable source of oxygen than passengers do (above a certain altitude, if a pilot has to be left alone, he has to don an oxygen mask); and since canisters release a lot of oxygen but only for a few minutes, this calls for the presence of oxygen tanks. |

How does oxygen change to When oxygen is breathed in and
carbon dioxide is breathed
out, how is the oxygen changed
to carbon dioxide? Or where
does the carbon dioxide come
from?
|

|
|
|
You breathe in oxygen, which your blood delivers to your cells so necessary chemical reactions can occur. Your cells then dump waste from the chemical reaction as carbon dioxide into your blood, which you breathe out. |
