Weekly Quiz Competition

Question 1
1 / -0

An example of infectious disease is:

A
Cholera

B
Anaemia

C
Joint pain

D
Cancer

Solution

Cholera is caused by bacterium Vibrio cholerae. It is a water borne disease and spreads through water contaminated by feaces and vomiting of the infected person.
So, the correct answer is 'Cholera'
Anemia, Joint pain and cancer are not caused by pathogens and hence are not infectious.
Question 2
1 / -0

The organisms which cause diseases in plants and animals are called:

A
Pathogens

B
Vectors

C
Insects

D
Worms
Solution
A) Correct option A

B) Explanation for the correct option:
Bacteria, viruses, fungi, protozoans, helminths, and other organisms have the potential to cause disease in humans. Pathogens are the organisms that cause disease in plants and animals.
Only a few insects and worms are capable of transmitting illnesses.
Vectors are just disease-causing organisms' carriers.
So, option (A) is the correct answer.
Question 3
1 / -0
Nitrogen is absorbed by the plants in the form of____________.
A
Ammonium

B
Nitrites

C
Nitrates

D
All of the above
Solution
- Plants can absorb nitrogen in the form of nitrites, nitrates, and ammonium ions during the assimilation process, after which they are converted into nitrogen-containing organic molecules, such as amino acids and DNA.
The correct option is D.
Question 4
1 / -0

Nitrogen is one of the essential constituents of all living organisms as part of

A
Proteins

B
Chlorophyll

C
Nucleic acids

D
All of the above

Solution

Nitrogen is one of the essential constituents of all living organisms as part of proteins, chlorophyll, nucleic acids and vitamins.
The correct option is D.
Question 5
1 / -0

Nitrogen fixation is the process of:

A
Conversion of atmospheric nitrogen into usable form

B
Conversion of ammonia into atmospheric nitrogen

C
Conversion of nitrate into atmospheric nitrogen

D
Conversion of atmospheric nitrogen into urea

Solution

All living organisms require nitrogen to synthesize important molecules like proteins. Nitrogen is abundantly available in the atmosphere. However, other than a few forms of bacteria, living organisms cannot use the atmospheric inert nitrogen molecule directly. It needs to be converted into a usable form like nitrate or nitrite. This process of converting the atmospheric nitrogen into a more usable form is called nitrogen fixation.
Thus, the correct answer is option A.
Question 6
1 / -0

Blue-green algae are able to fix nitrogen from the _________________.

A
Water

B
Atmosphere

C
Soil

D
None of the above

Solution

Blue-green algae present in the soil can fix the nitrogen present in the atmosphere.
The correct option is B.
Question 7
1 / -0

The circulation of nitrogen between organisms and the atmosphere is called the _____________________.

A
Atmosphere

B
Nitrogen cycle

C
Oxygen cycle

D
Water cycle

Solution

The circulation of nitrogen between organisms and the atmosphere is called the nitrogen cycle.
The correct option is B.
Question 8
1 / -0

The percentage of nitrogen in the atmosphere is_______.

A
75%

B
21%

C
1.03%

D
78%

Solution

Nitrogen is the most abundant gas in the atmosphere constituting 78% of all the gases.
The correct option is D.
Question 9
1 / -0

____________________ is an essential constituent of proteins, nucleic acids, chlorophyll and vitamins.

A
Nitrogen

B
Hydrogen

C
Oxygen

D
Calcium

Solution

Nitrogen is an essential constituent of proteins, nucleic acids, chlorophyll and vitamins.
The correct option is A.
Question 10
1 / -0

Rhizobium bacteria live in the root nodules of

A
Wheat

B
Palm trees

C
Legumes

D
None of the above

Solution

Rhizobium is found in the root nodule of leguminous plants and form a symbiotic relationship with it.
The correct option is C.
