1 / -0

I. Minimize the use of plastic bags.
II. Plastic is non biodegradable.

A
I and II both are correct, II is not the correct explanation to I

B
I and II both are correct, II is the correct reason for I

C
I and II both are wrong

D
I is correct and II is wrong

Solution

Polyethene is made by polymerization reaction. Organisms cannot use polyethene as source as carbon source. Thus it is non-biodegradable.
Question 2
1 / -0

Incinerator is ________.

A
Just a machine

B
It's a machine and process

C
It's a sterilizing machine

D
Both B and C

Solution

Biomedical wastes, industrial wastes, domestic wastes etc., are burnt in and incinerator at high temperature. Incineration is an industrial combustion process designed to reduce unwanted material to simple solid and gaseous residues.
Question 3
1 / -0

Which of the following is non-biodegradable?

A
Animal Bones

B
Nylon

C
Tea Leaves

D
Wool
Solution
- Non-biodegradable substances are substances that cannot be broken down into simple, environmentally safe materials by biological processes.
- In other words, these substances do not decompose.
- Nylon in the given options is a synthetic polymer and is nonbiodegradable.
Question 4
1 / -0

Find the odd one out:

A
Paper

B
Resin

C
Plastic

D
Rubber
Solution
Correct Option: A
Explanation:
- Solid waste that is generated must be segregated as dry waste and wet waste. This is the best way for the treatment and disposal of waste.
- Paper is wet waste whereas resin plastic and rubber are dry waste.
Hence, paper is the odd one among all.
Question 5
1 / -0

E-waste causes _________ pollution.

A
Soil

B
Water

C
Air

D
Sound
Solution
- The waste that is generated from electronic gadgets is called e-waste.
- Several hazardous materials/chemicals are categorized as e-waste like beryllium, Lead, Cadmium, etc.
- These get deposited in soil for a long period of time causing soil pollution.
Question 6
1 / -0

Which element is cause of itai itai disease?

A
$$Hg$$

B

Question 7
1 / -0

Which of the following chemicals is responsible for the depletion of ozone layer in the atmosphere?

A
Sulphur dioxide

B
Nitrous oxide

C
Chlorofluorocarbons

D
Carbon dioxide

Solution

Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants.
CFCs have destructive effects on the ozone layer.
Question 8
1 / -0

Dobson unit is used in measurement of __________ level.

A
Chlorofluoro carbons

B
Nitrous oxide

C
Ozone

D
UV-B radiation

Solution

A dobson unit is the most basic measure used in ozone research.OneDobson Unit (DU) is defined to be 0.01 mm thickness at STP (standard temperature and pressure). Ozone layer thickness is expressed in terms of Dobson units, which measure what its physical thickness would be if compressed in the Earth's atmosphere
So, the correct answer is 'Ozone'
Question 9
1 / -0

How does bioaccumulation occur?

A
By production of toxic substance

B
By Excretion of toxic substance

C
By usage of toxic substance

D
By consumption of toxic substance

Solution
