BUDGET 2010: TWO STRANGE THINGS

According to me the 2 most Important things of this budget are:

1-Can higher prices of Diesel/petrol be justified?
2-Change of personal income slab? why


Ans to the first question is today crude oil prices are hovering at 112 $ a barrel nearly half of 147 $ so why should the government bear the wasteful subsidy,especially when the oil companies are groaning under the burden.As our PM said now when economy is recovering and people can bear few extra bucks so save governments money for harder times.

The next important thing was change in annual tax slab,the strategy perhaps is that the higher disposable income would itself propel growth through higher consumer demand or else lead to long term savings through infrastructure bonds.A high savings rate is the best bet for any country as it offers long term funds for infrastructure.

Hence don't worry dude what FM is asking you is just spend more "consume" and don't worry when the crude prices again go high we will rescue you,but today u will have to pay.

What is a Rhizobium

Rhizobium is a symbiotic (diazotrophs) Nitrogen fixer which forms nodules in specific leguminous plants and fixes atmospheric nitrogen. They provide plant with nitrogen and take food (carbon) from them. They are heterotrophs possessing a special enzyme nitrogenase this enzyme allows them to convert nitrogen gas into ammonium.

Diazotrophs- An organism which is able to grow without external sources of fixed N. All diazotrophs contains Fe-Mo nitrogenase systems.

Morphology of Rhizobium bacteria:

1.Unicellular heterotrophs.

2.Small to medium sized 0.5-0.9 X 1.2-3.0 microns.

3.Gram negative non sporulating rods.

4.They are motile when young and have peritrichous flagella.

5.Cells contain characteristic granules of polymerized beta hydroxyl butyrate (40-50 % of cell dry weight).

6.Most strains produce gum (extracellular polysaccharide slime) of varying composition.

7.A large irregularly shaped nuclear region in centre surrounded by a narrow region of denser cytoplasm.
