Answer : The word that is different from the rest is: D: Mathura
Reasons:
- Geographical Location:
- Kanpur, Allahabad, and Varanasi are all cities located in the Indian state of Uttar Pradesh. Mathura is also located in Uttar Pradesh, but it is in a different region than the other three cities.
- Holy Significance:
- Kanpur, Allahabad, and Varanasi are all considered holy cities in Hinduism due to their association with the Ganges River.
- Mathura, although also a holy city in Hinduism, is not directly associated with the Ganges River. Instead, it is considered sacred due to its association with Lord Krishna, who is believed to have been born in Mathura.All except Mathura are cities situated on the banks of the Yamuna river.

The newton second (also newton-second, symbol N s or N·s) is the derived SI unit of impulse. It is dimensionally equivalent to the momentum unit kilogram metre per second (kg·m/s). One newton second corresponds to a one-newton force applied for one second. Derivation- p=mv =kg×m/s =kgm/s×s/s =kgm/s^2×s =N×s

Disease caused by ozone depletion:
- Skin cancer: Ozone depletion leads to an increase in ultraviolet (UV) radiation reaching the Earth's surface. UV radiation can damage the DNA in skin cells, leading to the development of skin cancer. Excessive exposure to UV radiation, especially UVA and UVB rays, increases the risk of developing skin cancer.
- Lung cancer: Although ozone depletion does not directly cause lung cancer, it indirectly contributes to the development of lung cancer. Ozone depletion can worsen air pollution, which is a major risk factor for lung cancer. Increased levels of air pollutants, such as particulate matter and toxic gases, can increase the risk of developing lung cancer.
- Respiratory disorders: Ozone depletion can also lead to respiratory disorders due to increased levels of air pollutants. Inhalation of pollutants such as nitrogen oxides, sulfur dioxide, and volatile organic compounds can cause respiratory irritation, inflammation, and damage to the respiratory system. This can lead to the development or exacerbation of respiratory disorders such as asthma, bronchitis, and chronic obstructive pulmonary disease (COPD).
- All of these: Considering the impacts of ozone depletion on skin cancer, lung cancer, and respiratory disorders, it can be concluded that all of these diseases are likely to be caused or exacerbated by ozone depletion.
In summary, ozone depletion can contribute to the development of skin cancer, lung cancer, and respiratory disorders due to increased UV radiation, worsened air pollution, and the inhalation of pollutants. It is important to take measures to protect ourselves from excessive UV radiation and address the causes of ozone depletion to minimize the health risks associated with it.

Acid: The compound that produces hydrogen ion when it dissolved in the solution is called acid.

• The acidic property depends on the concentration of the Hydrogen ion in the solution.

• H+ ion cannot exist alone. It always conjugates with the water and forms hydronium ion(H3O+)

The identification of the acidic or basic nature of any salt solution by the reactions:

• Strong acid + strong base → water + neutral salt
• Weak acid + strong base → water + basic salt
• Strong acid + weak base → water + acidic salt
• Weak acid + weak base → water + salt (It may be a neutral, acidic, or basic depending on the reactants used in the reaction)

EXPLANATION:

• KNO₃ is completely ionized in the water that gives the Nitric acid which is a strong acid. So KNO3 can be used for identifying an acid solution. Hence option 2 is correct.
• The K⁺ is an unreactive ion because it is produced from the dissolution of the strong base (KOH). So K2SO4 can't be used to identify the acidic solution.
• NaCl is a neutral solution that's why we can't use it also.
• Since Na2CO3 is formed by a weak acid Carbonic acid (H2CO3). That's why it can't be used also.

Intergenerational equity is the concept or idea of fairness or justice between generations.

Intra- generational equity is concerned with equity between people of the same generation and aims to assure justice among human beings that are alive today.

We can define Sustainable development as development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

Intergenerational and intra- generational equity are the underlying principles of sustainable development as:

Intergenerational equity tends to a fair utilization of resources by human generations in past, present and future, it tries to construct a balance of consumption of resources by existing societies and future generations.

Intra-generational equity makes sure that the resources which are not preserved for the future generation and are available for the current generation must be equally distributed among all the members of the present generation.

Auxin concentration increases on the shaded side of the plant.

Do not conclude that sound is a transverse wave that has crests and troughs. Sound waves traveling through air are indeed longitudinal waves with compressions and rarefactions. As sound passes through air (or any fluid medium), the particles of air do not vibrate in a transverse manner.

The driving force of an ecosystem is solar energy.
Solar energy plays a critical role in sustaining life on Earth and is the primary driving force behind all ecosystems. Here's a detailed explanation:
1. Solar energy:
- The sun is the ultimate source of energy for all living organisms on Earth.
- Sunlight is composed of electromagnetic radiation, and it provides the energy required for photosynthesis, a process used by plants and other organisms to convert sunlight, water, and carbon dioxide into glucose (a carbohydrate) and oxygen.
- Solar energy is responsible for the production of food and the transfer of energy through various trophic levels in the ecosystem.
2. Producers:
- Producers, such as plants and algae, are organisms that convert solar energy into chemical energy through photosynthesis.
- They capture sunlight and convert it into glucose, which serves as a source of energy for themselves and other organisms in the ecosystem.
- Producers are the foundation of the food chain and provide energy for herbivores and ultimately for carnivores and decomposers.
3. Biomass:
- Biomass refers to the total mass of living organisms present in a particular area or ecosystem.
- Solar energy, through photosynthesis, drives the production of biomass in the form of plants, algae, and other photosynthetic organisms.
- Biomass serves as a source of energy and nutrients for other organisms in the ecosystem.
4. Carbohydrates in plants:
- Carbohydrates, such as glucose produced during photosynthesis, are essential for the growth and development of plants.
- They store energy and serve as a source of carbon compounds for other organisms.
- Carbohydrates are vital for the functioning of ecosystems, but they are ultimately derived from solar energy through the process of photosynthesis.
In conclusion, solar energy is the driving force of an ecosystem as it provides the energy required for photosynthesis, which drives the production of food and biomass. This energy flow through the ecosystem supports the growth, reproduction, and survival of all organisms within it.

When a weak acid and a strong base combine to form a salt, the resulting compound will be basic with a pH greater than 7. In this case, the strong base will dominate the weak acid, leading to an overall basic nature of the salt.
