What did the white minority want from the new Constitution? 

• Protect its privileges and property: The white minority wanted the new Constitution to safeguard their existing privileges and property rights.


• A separate country for themselves: Some members of the white minority desired a separate country exclusively for themselves, where they could maintain control and dominance.


• Reservation in legislature: The white minority sought reservations in the legislature to ensure their representation and influence in the political decision-making process.


• Some special rights: The white minority also aimed to secure certain special rights that would preserve their social, economic, and political dominance over other racial groups.

 

Overall, the white minority's primary objective was to protect their privileges, property, and dominance in the new Constitution. They sought to maintain their position of power and control, either through reservations, special rights, or even the creation of a separate country.

 

Explanation:- During an election, When no party succeeds in securing a clear cut majority, then two or more parties join their hands (form an alliance) to form the government. This type of government is known as Coalition Government.

The Preamble proclaims that India is a Sovereign State. 'Sovereign' means that India has its own independent authority and it is not a dominion or dependent state of any other external power.

The correct answer is A and R both are true and R is the correct explanation of A.

Key Points

Trees as a shelter for animals:

• Trees provide shelter and food for a variety of birds and small animals, such as squirrels and beavers.
• Enhancing growth diversity, trees create an environment that allows the growth of plants that otherwise would not be there.
• Flowers, fruits, leaves, buds, and woody parts of trees are used by many different species.
• Deforestation can directly lead to biodiversity loss when animal species that live in the trees no longer have their habitat, cannot relocate, and therefore become extinct. 

Deforestation can lead certain tree species to permanently disappear, which affects the biodiversity of plant species in an environment.

Hence, the reason is also correct.

Important Points

Human activities that influence the extinction and endangerment of wild species fall into a number of categories:

• ​Land use practices like Deforestation, Projects in urban and suburban development, agriculture, and water management projects that encroach upon and destroy natural habitats.
• Unsustainable hunting and harvesting result in higher rates of death than new individual recruitment.
• Ecological damage caused by water, air, and soil pollution.
• Anthropogenic (human-caused) global climate change.
• ​According to the India State of Forest Report (ISFR) 2019, The forest and tree cover in the country is estimated at 80.73 million hectares, which is 24.56 percent of the total geographical area.​

Additional Information

The International Union of Conservation of Nature and Natural Resources (IUCN):

• For the purposes of conservation, the IUCN has divided the threatened plant and animal species into 9 categories.
• Endangered Species: It includes those species which are in danger of extinction. The IUCN's Red List of Threatened Species provides information about endangered species around the world.
• Vulnerable Species: This includes the species which are likely to be in danger of extinction in the near future if the factors threatening their extinction continue.
• Rare Species: The population of these species is very small in the world; they are confined to limited areas or thinly scattered over a wider area.

• Soils are complex mixtures of minerals, water, air, organic matter, and countless organisms that are the decaying remains of once-living things.
• Soils are formed as a result of weathering of rocks.
• India has varied relief features, landforms, climatic realms and vegetation types.
• These have contributed to the development of various types of soils in India.
• Each soil has unique properties and characteristics.

Key-Points
Riverine soil:

• Khadar and Bhangar are types of riverine i.e. alluvial soil.
• Alluvial soil is also known as riverine soil because it is found in river basins and is formed when the velocity of streams and rivers slows.
• Alluvial soil is formed by the deposition of sediments carried by rivers starting from the mountains (its origin).
• When the river overflows, this soil is deposited on the riverbanks.

​​Important Points
Some important points that distinguish between Khadar and Bhangar are:

Thus, Khadar and Bhangar are types of riverine i.e. alluvial soil.

Additional Infromation

Makherla soil: It is another name for laterite soil.
Regur soil: It is another name for black soil.
Urvara soil: It is the name for soils that are fertile in nature.

Low-income countries: These countries had per capita incomes of $935 or less in 2007. There were 49 countries in this category. About 20% of the world’s total population of about 6.5 billion people lived in low-income countries in 2007.

President Joe Biden has signed a $95 billion military aid package, featuring $61 billion for Ukraine, $26 billion for Israel, and $8 billion for the Indo-Pacific. Notably, the bill includes provisions targeting TikTok, giving parent company ByteDance nine months to sell the app before it’s banned in the US. Months of negotiation, lobbying by Ukrainian President Volodymyr Zelensky, and a split in the House Republican conference preceded the signing, posing challenges for House Speaker Mike Johnson’s leadership due to conservative opposition to increased aid for Ukraine.

DBS Bank India pledged USD 250 million to support new-age start-ups and 'new economy' companies, demonstrating its commitment to fostering innovation and entrepreneurship in India's start-up ecosystem amid challenges related to capital accessibility.

Exporters aiming for duty concessions on shipments to the UK must comply with new British regulations under the Developing Countries Trading Scheme (DCTS). Introduced by the UK Government, DCTS aims to integrate developing nations into the global economy, fostering trade partnerships and strengthening supply chains. It offers simpler, more generous preferential trading terms, reducing or eliminating tariffs on imports from 65 eligible countries, benefiting UK consumers and businesses while excluding certain upper-middle-income nations and those with UK free trade agreements.

Government of India and ADB have signed a $23 million loan agreement to strengthen the fintech ecosystem in India. Under this, an International Fintech Institute (IFI) will be established to strengthen fintech education, boost start-up success rate and promote fintech research and innovation.

The main source of variation in offspring is sexual reproduction.

Sexual reproduction involves the fusion of gametes from two parents, resulting in offspring that inherit a unique combination of genetic material from both parents. This process introduces variation in several ways:

• Independent assortment of chromosomes: During meiosis, the homologous pairs of chromosomes align randomly and separate into different gametes. This leads to different combinations of genes being passed on to the offspring.



• Crossing over: Crossing over occurs during meiosis when homologous chromosomes exchange segments of genetic material. This further increases genetic diversity by shuffling genes between chromosomes.



• Random fertilization: The chance of a specific sperm fertilizing a specific egg is random, leading to a nearly infinite number of possible combinations of genetic material in offspring.



• Mutations: Mutations, which are changes in the DNA sequence, can occur spontaneously or as a result of environmental factors. These mutations can introduce new genetic variations in the offspring.

While asexual reproduction, cloning, and parthenogenesis can also produce offspring, they do not involve the combination of genetic material from two parents and therefore do not introduce as much variation as sexual reproduction.

The direction of magnetic line of force is the direction of force on a North Pole, so the magnetic lines of force always begin on the North Pole of a magnet and end on the South Pole of the magnet. When a small magnetic compass is placed along a lie of force, it sets itself along the line tangential to it. Hence, the line drawn from the South Pole of the compass to its North pole shows the direction of the magnetic field.

Genetic Complement of an Organism
The genetic complement of an organism refers to the complete set of genes or genetic material that an organism possesses. It determines the characteristics and traits of an individual.
Options:
A. Genotype
- The correct answer is A. Genotype. The term "genotype" specifically refers to the genetic makeup or genetic constitution of an organism. It encompasses all the genes, including dominant and recessive alleles, that an individual carries.
B. Physiotype
- Physiotype is not the correct answer. The term "physiotype" is not commonly used in genetics. It may be confused with the term "phenotype," which refers to the observable physical and biochemical characteristics of an organism.
C. Phenotype
- Phenotype is not the correct answer. While phenotype is an important concept in genetics, it does not represent the genetic complement of an organism. Phenotype refers to the physical manifestation of an organism's genotype, including its observable traits and characteristics.
D. Morphotype
- Morphotype is not the correct answer. The term "morphotype" is not commonly used in genetics. It may be confused with the term "phenotype," which represents the physical characteristics of an organism.
In conclusion, the correct answer is A. Genotype, as it accurately represents the genetic complement of an organism.

When the dispersion medium is gas, the solution is called Aerosol and when the dispersion medium is liquid, the colloidal dispersion is known as Sol. Sols can further be classified into different types depending upon the liquid used.

Answer:
The correct answer is B: Composite fish culture.
Explanation:
Composite fish culture is a system of culturing multiple species of fish with different food habits in a fishpond. This method is widely practiced in aquaculture to maximize fish production and optimize the utilization of resources. Here is a detailed explanation of each option:
- Mariculture: Mariculture refers to the cultivation of marine organisms in the ocean or other saltwater environments. It involves the farming of various marine species such as fish, shellfish, and seaweed.
- Composite fish culture: Composite fish culture involves the culture of multiple species of fish with different feeding habits in the same fishpond. The combination of different species helps in utilizing the available resources efficiently and reducing competition for food.
- Capture fishing: Capture fishing refers to the practice of catching fish from natural water bodies like rivers, lakes, and oceans using various fishing gears and techniques.
- Pisciculture: Pisciculture is a broader term that encompasses the breeding, rearing, and culture of fish, including both freshwater and marine species. It involves activities such as fish farming, hatchery operations, and stocking of fish in natural water bodies.
In conclusion, the system of culturing five or six species of fish with different food habits in a fishpond is known as composite fish culture.

Resistance ‘R = 6ohm’ is related to length ‘L’, area of cross-section ‘A’ and resistivity ‘ρ’ as,

R = ρL/A

When L is doubled ,

As we know that the volume of the wire remains same.

old volume = new volume

AL = A'L' ....(i) ( as volume = area x length )

L' = 2L

So, from (i)

A' = A/2

So the new resistance is ,

R' = ρL'/A'

or

R' = ρ(2L)/(A/2) = 4 (ρL/A)

=> R' = 4R

thus, correct answer is option (b).

Find the HCF of 65 and 117,

117 = 1×65 + 52

65 = 1× 52 + 13

52 = 4 ×13 + 0

∴ HCF of 65 and 117 is 13.

65m - 117 = 13

65m = 117+13 = 130

∴m =130/65 = 2

Let the Cost Price of one article = Rs. 1
CP of x articles = Rs. x

When the train from Khandala starts off, the train from Lonavala will already have covered 50 kms.
Hence, 550 km at a relative speed of 60 kmph will take 550/60 hrs.
From this, you can get the answer as:
50 + (550/60) * 25 = 279.166 km.

If we assume the speed of the sound as 330 m/s, we can see that the distance traveled by the sound
in 45 seconds is the distance traveled by the train in 11 minutes.
330 × 45 = 660 × s Æ s = 22.5 m/s = 81 kmph

Let the average age of all the 17 persons = X years
Age of 17th persons = X + 8 years 
16 × 60.50 + X + 8 = 17 × X
976 = 16X 
X = 61 
So the answer = 61 + 8 = 69 years
Hence, Option D is correct.

The correct answer is Chaitanya. Chaitanya was a Bhakti saint and religious reformer who lived in the 16th century. He is known for developing different modes of religious emotionalism, such as vatsalya (parental love), dasya (servitude), sakhya (friendship), and madhuriya (divine love), that were aimed at fostering intense personal devotion to God. Chaitanya's teachings and devotional practices had a significant impact on the Bhakti movement in India and continue to be influential in modern Hinduism.

The 73rd Constitutional Amendment provided constitutional recognition and structure to the Panchayati Raj institutions, enhancing local self-governance.

Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup." Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus.

Counting Vibrations of a Tuning Fork
The number of vibrations of a tuning fork per second can provide information about the frequency of the wave. Here's a detailed explanation:
Frequency of a Wave:
- The frequency of a wave refers to the number of complete vibrations or cycles that occur in one second.
- It is typically measured in Hertz (Hz) or cycles per second.
- The frequency determines the pitch of a sound wave, with higher frequencies corresponding to higher pitches and lower frequencies corresponding to lower pitches.
Counting Vibrations:
- A tuning fork is a device that produces a specific pitch or frequency when struck.
- By counting the number of vibrations the tuning fork makes in one second, we can determine the frequency of the wave it produces.
- This can be done using various methods, such as using a stopwatch or a device specifically designed to measure frequency.
Importance of Frequency:
- The frequency of a sound wave is one of its fundamental characteristics.
- It helps us differentiate between different sounds and determine their pitch.
- By measuring the frequency of a tuning fork, we can compare it to the expected frequency and determine if it is in tune or not.
In conclusion, by counting the number of vibrations of a tuning fork per second, we can find the frequency of the wave it produces. This information is important for understanding the pitch of the sound and for tuning musical instruments.

Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves.

1st term = 0.5
2nd term = 0.5 + 0.05 = 0.55
3rd term = 0.55 + 0.1 = 0.65
4th term = 0.65 + 0.15 = 0.8

Thus, missing number is 5th term = 0.8 + 0.2 = 1
