Answer:
Ang isang monopolyo at isang oligopoly ay mga istruktura ng merkado na umiiral kapag mayroong hindi perpektong kumpetisyon. Ang isang monopolyo ay kapag ang isang solong kumpanya ay gumagawa ng mga kalakal na walang malapit na kapalit, habang ang isang oligopoly ay kapag ang isang maliit na bilang ng medyo malalaking kumpanya ay gumagawa ng katulad, ngunit bahagyang magkakaibang mga kalakal.
Answer:
True
Explanation:
Halogens belongs to the seventh group on the periodic table. This group contains the most reactive set of elements that we have. They require just an electron to achieve a noble and stable electronic configuration.
When halogens mostly in form of ChloroFluoroCarbons(CFCs) reaches the atmoshpere, ultraviolet rays release chlorine atoms which easily breaks away an oxygen atom from ozone. Ozone thereby turns into an oxygen gas with two oxygen atoms instead of three. This reaction depletes the ozone layer.
I could be wrong here but I think factories and animals are 2 ways carbon gets into the air because animals breath out carbon, while factories pollute the air with carbon. If anything I would think plants are responsible for removing it because they give out oxygen.
