Weekly Quiz Competition

Question 1
1 / -0

In treatment of waste, biological treatment is

A
Primary treatment

B
Secondary treatment

C
Tertiary treatment

D
Reverse osmosis stage
Solution
- The sewage treatment unit employs the primary, secondary and tertiary treatment for the complete process.
- In the primary treatment, filtration of the large and solid waste is done.
- Then in secondary treatment, the decomposing microbes are used for the breakdown of the organic sewage. So, the secondary treatment is the biological treatment of the wastewater.
- In the tertiary treatment, the chemical treatment is provided to the water.
Hence, the correct answer is 'Secondary treatment'
Question 2
1 / -0

Which one is a biological in sewage treatment?

A
Primary treatment

B
Secondary treatment

C
Tertiary treatment

D
All of the above

Solution

The sewage treatment unit employs the primary, secondary and tertiary treatment for the complete process. In the primary treatment, filtration of the large and solid waste is done. Then in secondary treatment, the decomposing microbes are used for the breakdown of the organic sewage. So, the secondary treatment is the biological treatment of the waste water. In the tertiary treatment, the chemical treatment is provided to the water.
Hence, the correct answer is 'Secondary treatment'
Question 3
1 / -0

Selectable marker that provides resistance to the antibiotic kanamycin is?

A
Gentamycin acetyltransferase

B
Hygromycin phosphotransferase(hpt)

C
Streptomycine phosphotransferase

D
Neomycin phosphotransferase(npt $$11$$)
Question 4
1 / -0

Chlorination of treated waste water is required for

A
Killing all microbes

B
Removing suspended materials

C
Complete breakdown of organic matter

D
All of the above

Solution

Chlorination is the process of treating the water with chlorine to kill the water-borne microbes that can possibly cause diarrhoea, typhoid, jaundice, amoebiasis etc. It is performed during the tertiary treatment step. Chlorine compounds like sodium hypochlorite are added to water to give effect to the process.
A. Chlorination kills the microbes.
B. Suspended particles are removed by filtration.
C. The complete breakdown of organic matter occurs by decomposition during the secondary treatment.
Hence, the correct answer is 'Killing all microbes'
Question 5
1 / -0

Sewage is broken down in

A
Primary treatment

B
Secondary treatment

C
Tertiary treatment

D
All of the above

Solution

The sewage treatment unit employs the primary, secondary and tertiary treatment for the complete process. In the primary treatment, filtration of the large and solid waste is done. Then in secondary treatment, the decomposing microbes are used for the breakdown of the organic sewage. In the tertiary treatment, the chemical treatment is provided to the water.
Hence, the correct answer is 'Secondary treatment'
Question 6
1 / -0

Neurospora is a very good taxon for.

A
Biofertilizer

B
Biological control

C
Genetically studies

D
Antibiotics
Question 7
1 / -0

Smack is chemically?

A
Diacetyl morphine

B
Diethyl morphine

C
Ethyl alcohol

D
$$3-4$$ Diacetylmorphine

Solution

Smack is one of the street names of heroin which is chemically diacetylmorphine. It is generally produced by the acetylation of crude morphine and is a narcotic analgesic that is used in the treatment of severe pain. Illicit heroin may be smoked or solubilised with a weak acid and then injected.

So, the correct answer is 'Diacetylmorphine'.
Question 8
1 / -0

Cyanobacteria helps farmers by

A
Reducing the alkanity of the soil

B
Reducing the acidity of the soil

C
Neutralising the alkanity of the soil

D
Water logging
Solution
- Cyanobacteria fix atmospheric nitrogen to nitrogen oxides (nitrates and nitrites). The oxides reduce the acidity of the soil.
- Too much acidity can cause plants to die thus cyanobacteria helps the growth of plants by reducing the acidity of the soil.
- Hence Cyanobacteria helps farmers by reducing the acidity of the soil.
- So, the correct answer is 'reducing the acidity of the soil'.
Question 9
1 / -0

Which one is correct about the free living Rhizobium sp. and its enzyme?

A
Bacteria are aerobic and nitrogenase are active

B
Bacteria are anaerobic and nitrogenase is active (operational)

C
Bacteria are aerobic and nitrogenase is inactive

D
Bacteria are anaerobic and nitrogenase is inactive
Question 10
1 / -0

Consider the following statements.
Mycorrhizal biotechnology has been used in rehabilitating degraded sites because mycorrhiza enables the plants to.
a. Resist drought and increase absorptive area
b. Tolerate extremes of pH.
c. Resist disease infestation
Of these statements.

A
$$2$$ and $$3$$ are correct

B
$$1$$ and $$2$$ are correct

C
$$1$$ and $$3$$ are correct

D
$$1, 2$$ and $$3$$ are correct
