Which of the following is true pair of biofertilizers : -
1 Azolla and BGA
2 Nostoc and legume
3 Rhizobium and grasses
4 Salmonella \& E. Coli
Explanation:
The term biofertilizers refer to the substance containing microorganism, it may be used to include all organic resources (manure) for plant growth through which are rendered in an available from for plant absorption microorganism or plant associations or interactions so in given pair Azolla and BGA is to pair of biofertilizer. - Biofertilizers are three types, nitrogen fixing becteria nitrogen-fixing cyanobacteria and mycorrhiza.

The biofertilizers are
1 Cowdung, manure
2 Anabaena and Azolla
3 Chemical manure
4 All of the above
Explanation:
Biofertilizers are the organisms that enrich the soil and increase the availability of nutrients to plants, increase plant yield, improve soil texture. - Nitrogen fixing bacteria and cyanobacteria and mycorrhizal fungi are example of biofertilizers. - Anabaena is free living nitrogen fixing bacteria and it also forms symbiotic association with water fern, Azolla. Azolla-Anabaena association is of great importance to agriculture.

Lowest number of chromosomes are found in:
1 Haplopappus
2 Cyprus
3 Salix
4 None of these
Explanation:
Lowest number of chromosomes are found in Haplopappus. It has diploid chromosome number of $2 \mathrm{n}$ $=4$. Haplopappus gracilis is flowering plant genus and belong to family Asteraceae. Cyprus has a diploid chromosome number of $2 \mathrm{n}=20$ and Salix has a diploid chromosome number of $2 \mathrm{n}=76$.

A scrubber in the exhaust of a chemical industrial plant removes:-
1 Gases like sulphur dioxide
2 Particulate matter of the size 5 micrometer or above
3 Gases like ozone and methane
4 Particulate matter of the size 2.5 micrometer or less
Explanation:
Gases like sulphur dioxide which is a major pollutant of chemical industrial plant is removed by an absorbent in the scrubber. - Dry scrubbing method is mainly used for acidic gases like sulphur dioxide $\left(\mathrm{SO}_2\right)$. Scrubbers are the pollution control device which mainly helps to remove some particulates and gases from industrial exhaust streams.

2 Fungicide
3 Rodenticide
4 Soil testing chemical
Explanation:
The combination of coppersulfate, lime and water, called Bordeaux mixture. This mixture is used as fungicide in farms and fruit garden which prevents them from mildew and fungi or fungal diseases.
