Consider the following processes: respiration, combustion, polymerization, nitrification, industrial fixation, and photosynthesis. how many of these result in the release of oxygen into the atmosphere?

The answer to the question "How many of the processes result in the release of oxygen into the atmosphere?" is only one of them does it: photosynthesis.

Explanation:

The photosynthesis occurs mostly inside plants. During this process, the plant needs carbon dioxide, light and water in order to release oxygen into the atmosphere.

The respiration is a process where oxygen is consumed and carbon dioxide is released into the atmosphere.

The combustion involves two participants: a fuel and an oxidizer. During this process, oxygen is consumed too and new chemical substances are created. Also, it generates heat during the process.

The polymerization is a process where simple molecules form chains and become more complex and bigger molecules. There are different types of this reaction and some of them use oxygen when they are forming bigger molecules. To conclude, this process do not release oxygen into the atmosphere.

The nitrification is a process that is made mainly by bacteria. During this process, those organisms need to use oxygen from the environment to be able to transform ammonia to nitrate. This is an important step to enrich the soil, but it do not release oxygen.

The industrial fixation is not a natural process. During this synthetic reaction, atmospheric nitrogen is transformed into nitrogen oxides or ammonium ions that bacteria can use in nitrification. It consumes oxygen too.

hi there,

on december 11, 2001, china officially became the 143rd member of the

world trade organization (wto) in the culmination of a negotiation

process which began in 1986. economists have long been debating the

global effects of china's accession to the wto, and as china becomes

fully integrated into the organization over the next several years,

the accuracy of their predictions will be tested.

one of the biggest residual effects of china's entry to the wto,

according to economists, will be the relocation of manufacturing and

distribution centers to china. due to its cheap labor, cheap

industrial land, and educated workforce, china is an ideal production

centre for businesses based in outside countries. this will likely

result in a twofold impact – more jobs will be available in china,

while countries like india, which have historically offered cheap

labor, will suffer. taiwan and malaysia's technology industries are

already suffering as companies like dell computers move production to

china, and while foreign investment soars in china, other asian

countries suffer. in addition, mexico and the caribbean will lose

thousands of garment manufacturing jobs as the u.s. lifts restraints

on chinese textile imports.

while the impact on southeast asia may be negative, the western world

may benefit. while some suggest china's open borders will result in

increased competition and a decreased employment rate for the western

world, western countries will benefit from access to china's highly

developed electronics and industry sectors. with duties and quotas

slashed, and restrictions lifted, multinationals will benefit by

setting up distribution centers without the need for chinese

middlemen. in addition, it's expected that china will import massive

amounts of food products, machinery and vehicles from the u.s., japan,

hong kong, taiwan, singapore and south korea, thus providing

significant boosts to these countries' economies.

in conclusion, it seems that while western countries may benefit from

china's accession to the wto, there's the potential that asian and

south american countries may feel the pinch of free trade as china

moves to a global economy.
