Army Cadet College (ACC) Mock Test - 1 - Army Cadet College (ACC) MCQ

The logic followed here is:

In figure 1:

32 = (2 + 2) × 8

4 × 8

32

In figure 2:

24 = (3 + 1) × 6

4 × 6

24

Similarly,

In figure 3:

45 = (4 + ?) × 5 

4 + ? = 9

? = 9 - 4

? = 5

Hence, the correct answer is "5".

The correct answer is Seven Five Year Plan.

Key Points

• Seventh Five-Year Plan(1985-1990):
  • ​The Seventh Plan aims at extending the green revolution to new areas through its emphasis on raising the productivity of rice in the eastern region and rainfed and dryland agriculture. This should lead to faster growth in agricultural output in areas that, in the national context, are economically backward.
    • The induction of new technologies and the pursuit of economic growth should not be at the expense of the environment. In the long run, environmentally sound policies are also developmentally sound ones.
    • Provide gainful employment to the unemployed, particularly women and youth,
    • Raise the earnings of those already employed in low-paid jobs.
    • Step-up the productivity and earnings of those who are self-employed workers.
    • Improve the access of the urban poor to basic amenities like education, health care, sanitation, and safe drinking water.

The idiom by fits and starts implies doing something irregularly and without any routine or regular schedule to do that particular thing. Among the given options we can choose option B since it gives us the correct meaning of the said idiom whereas the rest can be eliminated since they are irrelevant here.

This makes option B the correct choice among the given options.

Let us first learn the meanings of the given words:
Significantly (adverb): in a sufficiently great or important way as to be worthy of attention.
Exponentially (adverb): in a way that becomes quicker and quicker as something that increases becomes larger.
Rapidly (adverb): very quickly; at a great rate.
Grammatically only adverb is apt for the blank, thus ‘significantly’, ‘exponentially’ and ‘rapidly’ are suitable options for the blanks.
Hence, the correct answer is option B.

Conduction of water and minerals in plants takes place in conducting vessels, located in the core, called Xylem. Thus conduction of water is not the function of the epidermis but Xylem.

• Pollution occurs when a substance present in the environment prevents the functioning of natural processes and produces harmful environmental and health effects.
• In the natural world, many substances accumulating in the environment are processed through the intricate network of biogeochemical cycles.
• Water pollution occurs when harmful substances, chemicals or microorganisms contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment.​

Key Points

​Sources: 

• industrial effluents
• agricultural runoffs
• surface runoffs
• the municipality (urban) and domestic wastes
• substances produced from energy production
• mining
• oil spill

Important Points

Run-off urban areas: 

• Urban runoff is surface runoff of rainwater created by urbanization.
• This runoff is a major source of flooding and water pollution in urban communities worldwide.
• Impervious surfaces (roads, parking lots and sidewalks) are constructed during land development which results in high amount of surface runoff.
• It is mostly inorganic in nature with gasoline, motor oil, heavy metals, trash and other pollutants from roadways and parking lots.

Run-off from agricultural forms: 

• Agricultural Runoff is water from farm fields due to irrigation, rain, or melted snow that flows over the earth that can absorb into the ground, enter bodies of waters or evaporate.
• This runoff can contain organic pollutants like pesticides, sediment (soil particles), nutrients (phosphorus, nitrogen and potassium from fertilizers) and metals, which can contaminate sources of water.

Sewage effluents:

• Sewage, or domestic/municipal wastewater, is a type of wastewater that is produced by a community of people.
• It is characterized by physical, chemical and toxic constituents, and its bacteriologic status.
• It consists mostly of greywater (from sinks, bathtubs, showers, dishwashers, and clothes washers), blackwater (the water used to flush toilets, combined with the human waste that it flushes away), soaps and detergents, and toilet paper (less so in regions where bidets are widely used instead of paper). 
• Sewage effluents have the highest amount of organic pollutants along with bacterial contamination.

Industrial effluents:

• Industrial effluent is the wastewater produced by industrial activity.
• It includes wastewater produced from the manufacturing process or cleaning process.
• The composition of wastewater generated mostly depends on the nature of the industry.
• It is mostly inorganic in nature.

​Thus, the major source of water pollution is domestic sewage or dirty water, industrial effluent, silt and mineral oil.

Additional Information

Effects:

• Water pollution leads to excessive buildup of nutrients nitrogen and phosphorus in the water body called nutrient enrichment.
• Excess nutrient buildup leads to algal bloom in the water body eventually leading to eutrophication.

The cells lining the proximal convoluted tubule are well adapted for reabsorption of materials from the filtrate. The cells reabsorb entire glucose, amino acids, most of the inorganic ions (Na⁺, K⁺, Cl ), much of the water as well as some urea from the filtrate.

To determine which of the given options is a heterogeneous mixture, let's examine each option individually:
A: Air
- Air is a mixture of gases, mainly nitrogen (78%), oxygen (21%), and small amounts of other gases such as carbon dioxide, argon, and trace elements.
- It is a homogeneous mixture because the composition is uniform throughout.
B: Brass
- Brass is an alloy composed of copper and zinc.
- It is a homogeneous mixture because the copper and zinc atoms are evenly distributed throughout the material.
C: Iodised table salt
- Iodised table salt is a mixture of sodium chloride and small amounts of iodine.
- It is a heterogeneous mixture because the iodine is not evenly distributed throughout the salt. The iodine appears as small specks or crystals in the salt.
D: Steel
- Steel is an alloy composed of iron and carbon, along with small amounts of other elements.
- It is a homogeneous mixture because the iron and carbon atoms are evenly distributed throughout the material.
Therefore, the correct answer is C: Iodised table salt as it is a heterogeneous mixture due to the uneven distribution of iodine within the salt.

Concept:

Energy:

• Energy is the capacity or ability to perform work.
• It could exist in several different forms, such as potential, kinetic, thermal, electrical, chemical, radioactive, etc.

Energy crisis:

• Any significant disruption in the supply of energy resources in an economy is considered an energy crisis.

Explanation:

Alternative energy:

• Alternative energy comes from sources other than fossil fuels, and as a result, it emits little or no greenhouse emissions like carbon dioxide (CO2).
• This indicates that energy is generated from several sources.
• Examples of alternative energy are solar power, wind power, hydropower etc.
• The wisest course of action to solve the energy crisis is to reduce global reliance on non-renewable resources while enhancing the use of alternative energy.

Thus, the solution to energy crises is alternative energy.

Additional Information Hydroelectric energy:

• This source of energy is the kinetic energy of flowing water or the potential energy of water at a height.
• Hydropower plants convert the potential energy of falling water into electricity.

Petroleum:

• Petroleum is a dark oily liquid.
• It has an unpleasant odour.
• It is a mixture of various constituents such as petroleum gas, petrol, diesel, lubricating oil, paraffin wax, etc.

Coal:

• Coal is one of the fuels used to cook food.
• Earlier, it was used in railway engines to produce steam to run the engine.
• It is also used in thermal power plants to produce electricity.
