Question

1- In some parts of Ontario, farm land is being replaced by industry and paved roadways. If this trend continues, what gas will build up in the atmosphere? Explain your answer.

​2- Explain why legumes contain more protein than any other plant group.

Answer 1

Solution

Ans.1

Carbon dioxide (CO2) (mostly)

Concentrations level of carbon dioxide and other greenhouse gases in the atmosphere have increased since the beginning of the industrial era. Almost all of this increase is attributable to human activities.and also sulphur dioxide and nitrogen dioxide and argon also added by a industrial area.

CO2 is the main greenhouse gas produced by motor vehicles

In vehicles, the principal greenhouse gas is carbon dioxide (CO2), but vehicles also produce the greenhouse gases nitrous oxide and methane. Not all vehicles have the same impact though

Ans.2

Because 4 Protein Levels Compared to Other Plants.

legumes are rich in proteins because they can use nitrogen fixed by their symbiotic nodules to produce endogenous proteins. Nodules fix The atmospheric nitrogen into the plants in the form of ammonia. Ammonia is first used to made of aminoacids. All proteins contain nitrogenous amino acids. Nitrogen is therefore a necessary ingredient in the production of proteins. Hence, legumes are among the best sources of plant protein.
