Question Discussion & Solution

The correct answer is Mode of Nutrition.

• In 1969, R.H. Whittaker introduced the five-kingdom system of classification.
• In the five-kingdom system, the basis of classification is the complexity of cell structure, physical organization, nutrition method, and life cycle.
• Aristotle firstly divided the living world into two groups, namely, flora and fauna.
• After that, in his book 'Systema Naturae', Linnaeus classified all animals into plants and animals.
• Linnaeus is called the 'father of modern classification system'.

Additional Information

• Whittaker classified all creatures in the following five kingdoms -

1. Kingdom Monera-
   • ​​This world consists of prokaryotic organisms ie Bacteria, Cyanobacteria, and Archaebacteria.
2. Kingdom Protista-

• This world consists of unicellular eukaryotic organisms. Yuglina, which is situated between plants and animals, is included in this world.

3. Kingdom Fungi-

• This includes organisms dependent on parasites and dead food for food. Their cell wall is made of chitin.

4. Plant World (Kingdom Plantae)-

• This world consists of algae and multicellular green plants.

5. Kingdom Animal-

• This includes all multicellular animals. It is also called 'Metazoa'.

According to the question:

Since 7 is the part of the men as well as the women.

So, 7 men are women.

Hence, 7 is the correct answer. 

Note: If in the question asked "how many men are only women", then the answer, in this case, would be 0.

CONCEPT:

• The Correct Answer is Option (3) i.e. 1-d, 2-c, 3-b, 4-a.

The correct answer is SRAM.

​Key Points

• SRAM memory devices are very much similar, mainly in terms of speed, to the cache memory.
• SRAM stands for Static random-access memory.
• Static random-access memory is a type of random-access memory that uses latching circuitry to store each bit.
• SRAM is volatile memory; data is lost when power is removed.
• The term static differentiates SRAM from DRAM which must be periodically refreshed.

Additional Information

• Dynamic random access memory (DRAM) is a type of semiconductor memory that is typically used for the data or program code needed by a computer processor to function.
• Flash memory, also known as flash storage, is a type of nonvolatile memory that erases data in units called blocks and rewrites data at the byte level.
• EEPROM (electrically erasable programmable read-only memory) is user-modifiable read-only memory (ROM) that can be erased and reprogrammed (written to) repeatedly through the application of higher than normal electrical voltage.

The correct answer is Viticulture.

• Cultivation of grapes called Viticulture.

Key Points

• Cultivation of grapes either for wine production or for raw consumption (table grapes) is called Viticulture.
• China is the leading producer of grapes.
• It accounts for 16.9% of global production.
• China is followed by Italy at 10.8%, and later by the United States at 8.7%.

Additional Information

• Horticulture is a type of agriculture in which fruits and vegetables are grown.
• The breeding, rearing, and transplantation of fish are called pisciculture.
• Sericulture is the production of raw silk by means of raising caterpillars.
