The correct answer is Snake, Frog, Cockroach.

Concept:

Cold-blooded organisms

• Cold-blooded organisms are also known as ectothermic organisms.
• Cold-blooded organisms are incapable of controlling their body temperature.
• They rely on external sources of heat to regulate their body temperature.
• Snakes, frogs, lizards, earthworms, and cockroaches are cold-blooded organisms.

Warm-blooded organisms

• Warm-blooded organisms are also known as endothermic organisms.
• These organisms can internally regulate their body temperature, often maintaining a relatively constant temperature regardless of the external environment.
• Parrots, dolphins, pigeons, humans, and Whales are warm-blooded organisms.

Explanation:

Option 1: Lizard, Parrot, Dolphin

• Lizard: Lizards are cold-blooded reptiles that cannot internally regulate their body temperature and rely on external sources of heat.
• Parrot: Parrots are warm-blooded birds that can maintain a relatively constant body temperature through metabolic processes.
• Dolphin: Dolphins are warm-blooded marine mammals that have the ability to maintain a constant body temperature despite the surrounding water temperature.

Option 2: Pigeon, Humans, Lizard

• Pigeon: Pigeons are warm-blooded birds that can maintain a relatively constant body temperature through metabolic processes.
• Humans: Humans are warm-blooded mammals with the ability to regulate their body temperature internally.
• Lizard: As mentioned earlier, lizards are cold-blooded reptiles that rely on external sources of heat for temperature regulation.

Option 3: Snake, Frog, Cockroach

• Snake: Snakes are cold-blooded reptiles that rely on external heat sources to regulate their body temperature.
• Frog: Frogs are cold-blooded amphibians that have body temperatures influenced by the environment.
• Cockroaches: Cockroaches are cold-blooded insects that do not have the ability to regulate their body temperature internally.

Option 4: Whale, Frog, Earthworm

• Whale: Whales are warm-blooded marine mammals that can maintain a constant body temperature even in cold water.
• Frog: As mentioned earlier, frogs are cold-blooded amphibians that have body temperatures influenced by the environment.
• Earthworm: Earthworms are cold-blooded invertebrates that have body temperatures tied to their surroundings.

Thus, Snakes, frogs, and cockroaches are cold-blooded organisms.

The correct answer is Evaporation.

Key Points

• The electrical appliance which keeps the object cool is called a refrigerator.
  • The refrigerator works on the Carnot cycle.
  • An ideal cycle that gives maximum possible efficiency is called the Carnot cycle.
  • The first refrigerator was built by John Gorrie in 1844.
  • The five basic parts of a refrigerator are an expansion valve, evaporator coils, compressor, Radiator pipes, and refrigerant.
  • The expansion valve lowers the temperature of the refrigerant by expanding it, and then it flows through the chilling cabinet, cooling it down.
  • The other components control the flow of refrigerant and radiate out the heat.
• The basic principle is that whenever a liquid coolant is passed through things at a higher temperature, it absorbs the heat; gets evaporated and the cooling effect is produced.
• The Refrigerator works on the principle of evaporation. So option 4 is correct.

The correct answer is option 3.

Key Points

• Lysosomes: These are membrane-bound vesicular structures formed by the process of packaging in the Golgi apparatus.
• These are also called ''Suicidal bags'' because of their phagocytic activity. Lysosome keeps the cell clean by digesting any foreign material as well as worn-out cell organelles.
•  If any cell or cell organelle gets damaged, the lysosome digest the damaged cell or cell organelle by the application of hydrolytic enzymes (hydrolases – lipases, proteases, carbohydrates)

Additional Information 

• Ribosomes are responsible for the protein formation
• Mitochondria produce ATP for the cell that is why they are also called the Powerhouse of the Cell

The correct answer is Al.

 Key Points

• Al metal is extracted by electrolysis only.
• Aluminium is extracted by the electrolysis of alumina mixed with molten cryolite.
• This process is known as the Hoope’s process.
• In this process, the impure aluminium is collected over the anode and the pure aluminium is obtained on the cathode with a salt of the metal being the electrolyte.

 Additional Information

• During the electrolytic refining of aluminium metal, the impure metal/ore is placed at the anode of an electrolytic cell while the cathode is a thin plate of pure aluminium metal.
• The electrolyte consists of the solution of a salt of the aluminium metal, i.e.cryolite and calcium fluoride.
  • On passing the electric current, the pure aluminium metal from the anode dissolves and gets deposited at the cathode.
  • The soluble impurities go into the solution while the remaining insoluble or the less electropositive impurities settle down below the anode as anode mud or sludge.
  • electrolysis is involved in the refining stage of copper production, it is not the primary method for extracting copper from its ores. Smelting is the primary extraction method, and electrolysis is used in the refining process to purify the obtained copper.
    • The difference lies only in the electrolyte and the substances placed at the respective anode and cathode.​

  • He estimated the national income by first estimating the value of agricultural production and then adding a certain percentage of non-agricultural production.
  • The first person to adopt a scientific procedure for estimating the national income was Dr V K R V Rao in 1931. He divided the Indian Economy into two parts :
  • Agricultural Sector included agriculture, forests, fishing, and hunting.
  • The corporate Sector included industries, construction, business, transport, and public services.
  • The product method was used for estimating income in the agricultural sector and the income method was used for estimating income in the corporate sector.

Additional Information

• The Government of India appointed National Income Committee in 1949.
• Since 1955 the national income estimates are being prepared by Central Statistical Organisation.
• The Central Statistical Organisation has divided the Indian economy into three basic sectors:
  • The primary sector comprises agriculture, forestry, fishing, mining, and quarrying.
  • The secondary sector comprises manufacturing, power generation, gas, and water supply.

Given:

In the given figure, O is the point of intersection of two chords AB and CD such that OB = OD

Concept Used:

According to the chord intersection theorem, the product of two intersecting inside-the-circle chords' segments is equal.

Solution:

Given that, O is where the chords AB and CD converge and  OB = OD

The type of triangles OAC and ODB must be determined.

According to the chord intersection theorem, the product of two intersecting inside-the-circle chords' segments is equal.
As a result, the segment product is: OA x OB = OC x OD

∴  OA = OC and OB = OD.

In ΔOAC, OA and OC lengths are equal.

∴ The triangle is isosceles.

In ΔOBD, OB and OD lengths are equal.

∴ The triangle is isosceles.

Due to the resemblance characteristic, identical triangles have congruent corresponding angles and proportionate corresponding sides.

  (Vertically opposing angles)

OA = OB = OC = OD (radius)

∴ The corresponding sides and angles are equal.

The triangles OAC and OBD are hence comparable.

Hence, the triangles OAC and OBD are similar and isosceles.

Calculation:

Total % of D1 and D4 = 12 + 14

⇒ 26%

Total % of D2 and D7 = 11 + 11

⇒ 22%

Difference = 26% - 22%

⇒ 4%

Difference in amount = 4962000 × 4%

⇒ 198480

∴ The required answer is Rs. 1,98,480.

Let the age of two persons be 4x and 5x

According to the question,

Age of another person = (60/100) × 5x = 3x      ----(i)

∴ 4x – 3x = 14

⇒ x = 14

∴ Age of three persons in the group = 3 × 14, 4 × 14, 5 × 14 = 42, 56, 70

Average age of the group = (42 + 56 + 70)/3 = 56

∴ The average age of the group is 56

Given

The distance between two pillars of length 16 m and 9 m is x meters.

Two angles of elevation of their respective top from the bottom of the other are complementary to each other.

Concept used

If two angles of elevation are complimentary to each other then H = √ab

Where a and b are the Length of the pillars.

Calculation

AB and CD are two pillars of Length 16 m and 9m.

Let the angle of elevation at B and D be θ and (90 - θ)

Distance between two pillars BD be x metres

IN Δ ABD

Tanθ = AB/BD = 16/x       - - - -(i)

In Δ BDC

Tan(90 - θ) = CD/BD = 9/x

Cotθ = 9/x                       - - - - (ii)

Multiply equation i and ii

⇒ Tanθ × Cotθ = (16/x) (9/x)

⇒ 144/x² = 1

⇒ x² = 144

⇒ x = 12 m

Alternate Method
If two angles of elevation are complimentary to each other then H = √ab

Where a and b are the Length of the pillars.

H = 

H = √144

H = 12 m

Formula used:

Effective discount = x + y - (x × y)/100

effective discount = (Article get free)/(Total articles) × 100

Calculation:

Scheme A. Buy 6 get 4 free

So, effective discount for scheme A is = (Article get free)/(Total articles) × 100

= 4/(6 + 4) × 100 = 40%

Scheme B. Buy 5 get 5 free

So, effective discount for scheme B is = (Article get free)/(Total articles) × 100

= 5/(5 + 5 ) × 100 = 50%

Scheme C. Two successive discounts of 18% and 24%

= 18 + 24 - (18 × 24)/100

= 42 - 4.32

= 37.68%

B has the maximum discount percentage.

Solution:

Number of apples in the basket = 6a

Number of oranges in the basket = 5a

difference between apples and oranges in the basket is 8

6a - 5a = 8

a = 8

Number of apples in the basket = 6a = 48

Number of oranges in the basket = 5a = 40

If x apples and (x + 2) oranges were rotten then,

Number of fresh apples to oranges are in the ratio 4: 3

(48 - x)/(40 - (x + 2) = 4/3

(144 - 3x) = (160 - 4x - 8)

-8 = -x 

x = 8

Total number of rotten oranges and apples in the basket is (8 + 8 + 2) = 18

Hence, option(3) is correct.

The correct answer is '(B)​.'

Key Points

• The error lies in part (B) of the sentence.
• We use if to introduce a possible or unreal situation or condition.
  • Example: You can only go in if you’ve got your ticket.
• We use when to refer to the time of a future situation or condition that we are certain of.
  • Example: When I’m older, I’d love to be a dancer.
• Therefore, the use of 'if' in part '(B)​​' part of the sentence should be replaced by 'when' to make it grammatically correct.
• Hence, the correct answer is '(B)​.'
• Correct sentence: He was worn out when he got home.

Additional Information  

• The present tense is the base form of the verb.
• We use do and does to make questions with the present simple.
• We use does for the third person singular (she/he/it) and do for the others.
• We use do and does with question words like where, what and when.
  • Example: Where do Angela and Rita live?

Hinglish

• त्रुटि भाग part (B) में निहित है।​
• हम किसी संभावित या अवास्तविक स्थिति या स्थिति का परिचय देने के लिए if का उपयोग करते हैं।
  • Example: You can only go in if you’ve got your ticket.
• हम भविष्य की स्थिति या स्थिति के समय का उल्लेख करने के लिए when उपयोग करते हैं, जिसके बारे में हम निश्चित हैं।​
  • Example: When I’m older, I’d love to be a dancer.

The correct answer is 'DECAB'.

Key Points

• The given question is an example of a Para Jumble.
• We know that the first statement of a para jumbled question is usually an independent general statement, a noun, a universal fact, starting of an incident, or it starts with 'most' or 'once'.
• The correct sequence to form a coherent paragraph is: DECAB.
  • D. The Dead Sea is one of the saltiest bodies of water on the planet, with about ten times the salt content of typical saltwater.
  • E. This is because water flows into the Dead Sea from a single primary tributary, the Jordan River.
  • C. It is then unable to exit the lake and is forced to evaporate.
  • A. Because of the region's scorching heat and aridity, a considerable amount of water evaporates.
  • B. As a result, the salt and other minerals become increasingly concentrated.
• This arrangement also makes sense. It begins by stating the uniqueness of the Dead Sea's saltiness (D) and then explains the reason behind this high salt content (E). Subsequently, it describes the inability of water to exit and the subsequent evaporation (C), which is due to the extreme heat and aridity of the region (A).
• Finally, it concludes by linking the consequence of water evaporation to the increased concentration of salt and minerals (B). This sequence creates a logical flow of information, explaining the characteristics and factors contributing to the Dead Sea's high salinity. 
• Thus, the correct answer is Option 1.
   

Correct Answer: The Dead Sea is one of the saltiest bodies of water on the planet, with about ten times the salt content of typical saltwater. This is because water flows into the Dead Sea from a single primary tributary, the Jordan River. It is then unable to exit the lake and is forced to evaporate. Because of the region's scorching heat and aridity, a considerable amount of water evaporates. As a result, the salt and other minerals become increasingly concentrated.
