Answer:

The reason the compressed air gets cold after being used is due to a process known as adiabatic cooling, a property of thermodynamics. A gas, initially at high pressure, cools significantly when that pressure is released. The compression needed to turn a gas to liquid allows a large amount of gas to fit in a relatively small space, and when that gas is released to a large space, it rapidly expands to fill the space.

Which of these gymnosperms are known to be important in maintaining the balance of carbon in an ecosystem?

CaHeK987 [17]

The correct answer is: [D]:

___________________________________________________

→ " redwood tree forests " .

___________________________________________________

Note: Let us consider the other answer choices.

___________________________________________________

Choice: [A]: "garden flowering plants" ; is incorrect — since these are not generally considered to be part of a true or traditional "ecosystem" ; and especially since "garden flowering plants" are, in fact, "flowering plants" — which means that they are "angiosperms" — Not "gymnosperms ".

→ Rule out: " Choice: [A] " .

__________________________________________________

Choice: [B]: " ferns and liverworts " ; is incorrect — since both ferns — as well as liverworts — are Not "gymnosperms ".

Liverworts are "bryophytes" {which lack true vascular tissue] ; and ferns are "pterophytes" ["seedless vascular plants"].

→ Rule out: " Choice: [B] " .

___________________________________________________

Choice: [C]: " mosses and horsetails "; is incorrect ; since both mosses — as well as horsetails — are Not "gymnosperms ". Mosses are "bryophytes" (see aforementioned) ; and horsetails are "non-seed bearing plants" that spread vegetatively [underground; by asexual reproduction — and Not by seed .].

→ Rule out: " Choice: [C] " .

__________________________________________________

Choice: [D]: " redwood tree forests " ;

— is the only answer choice provided that is a "gymnosperm".

Furthermore, the "redwood tree" is a conifer (i.e. "coniferous; or, "cone-bearing" plant} that reproduces through seeds spread by "cone") — and all "conifers" are a type of "gymnosperm."

Furthermore, "redwood trees" grow large and tall, and redwood forest communities within an ecosystem; due to there size and presence, are: "known to be important in maintaining the balance of carbon in an ecosystem."

__________________________________________________

→ As such, the correct answer is:

__________________________________________________

→ Answer choice: [D]: " redwood tree forests " .

What experimental evidence leads scientists to believe that only quantized electronic energy states exist in atoms?

iogann1982 [59]

The experimental evidence that leads scientists to believe that only quantized electronic energy states exist in atoms was the Niels Bohr experiment on Hydrogen gas. The quantized model for electron orbits in atoms that effectively explained the spectroscopic behavior of the atoms. Each line in the spectrum corresponds to one exact frequency of light emitted by the atom.
