Key Points

• The organisms that live and feed on dead organic matter and obtain nutrition for their growth are called saprophytes.
  • Example- mucor, yeast. Saprophytes are mostly fungi and/or bacteria.
  • Saprophytes decompose dead plants and animals and convert complex molecules into simpler molecules.
• Rhizopus is a fungus commonly found in soil.
  • It is a saprophyte, meaning it obtains nutrients by decomposing organic matter.
  • Rhizopus plays a role in the decomposition of dead plants and other organic material.

Additional Information

• Cuscuta, commonly known as dodder, is a parasitic plant that lacks chlorophyll.
  • It attaches itself to a host plant and derives nutrients by tapping into the host's vascular system.
• Spirogyra is a filamentous green algae.
  • It is an autotrophic organism, meaning it produces its food through photosynthesis.
  • Spirogyra contains chlorophyll and does not rely on external organic matter for nutrition. 
• Grass is a type of plant that is generally autotrophic, producing its own food through photosynthesis.
  • Grasses typically have chlorophyll and obtain nutrients through the process of photosynthesis.

Given:

Principle = Rs. 10240

rate = 12.5%

Time = 3yrs.

Formula Used:

⇒  A = P {1 + (r/100)} n

Where, A = Amount, r = Rate% and n = No. of years.

Calculation:

⇒ A = 10240 {1 + (12.5/100)} n

⇒ A = 10240 {1 + (1/8)}³

⇒ A = 10240 (9/8)³

⇒ A = 10240 × (9/8) × (9/8) × (9/8) = Rs. 14580

∴ Rajnish will get Rs. 14580 after 3 years.

The logic followed here is:

'HIGHLY’ is written as ‘GRHYOH',

So, 'HORROR' will be written as 'RLHRLR'.

Hence, the correct answer is "Option 2".

Key Points

• Ajeya Warrior 2023:-
  • It is a bilateral military exercise between India and the United Kingdom.
  • It is the seventh edition of the exercise, which is held alternately in India and the UK.
  • The 2023 edition of the exercise was held at Salisbury Plain, UK from 27 April to 11 May 2023.
  • The exercise involved soldiers from the 2 Royal Gorkha Rifles of the British Army and the Bihar Regiment of the Indian Army.
  • The Indian Army contingent arrived in the UK on 26 April 2023 by an Indian Air Force C-17 aircraft with indigenous weapons and equipment.
  • The aim of the exercise was to enhance interoperability between the two armies and to promote the ability to operate together while undertaking company-level subconventional operations in urban and semi-rural environments under a UN mandate.
  • The scope of the exercise included a command post exercise at the battalion level and a company-level training exercise.

The correct answer is "Physical Change".

Key Points

• Physical change is a type of change where the physical properties of matter change. A change of state of matter, change in color, odor, solubility, etc. all are examples of physical change.
• During a physical change, neither the composition nor the chemical nature of matter is changed. During this change, molecules rearrange themselves without affecting the internal composition. A physical change doesn't affect the chemical property.
• Dissolution of sugar in water is a physical change because it doesn't result in the formation of a new substance. It is a reversible change as sugar and water can be extracted back from the solution by the process of crystallization followed by evaporation.

Additional Information

• Chemical Change is a change of material into another. New materials with different properties and one or more than one new substance are formed.

Given:-  14 ÷ 7 × 1 + 3 - [18 - {15 - (7 - 7 - 2)}]

Concept used:-

Calculation:-

⇒ 14 ÷ 7 × 1 + 3 - [18 - {15 - (7 - 7 - 2)}]  

⇒ 14 ÷ 7 × 1 + 3 - [18 - {15 -( -2)}] 

⇒ 14 ÷ 7 × 1 + 3 - [18 - {17}] 

⇒ 14 ÷ 7 × 1 + 3 - [1]  

⇒ 2 × 1 + 3 - 1 

⇒ 5 - 1 = 4 

∴ The required answer is 4.

Given:

Persons: A, B, C, D, E, and F 

Days: Monday to Sunday.

Conditions are as follows:

1. There is no exam on Thursday.

2.  E's exam is on Saturday.

3. The exams of A and F are separated by one day which is the gap day.

4.D's exam is immediately before F but is immediately after C. 

5. B's exam is on Sunday. 

Analyzing all the conditions, we get,

So D's exam is on Tuesday.

Hence, the correct answer is option 4).

Key Points

• The "One tap -One tree" scheme was jointly launched by the Namami Gange Programme and the Rural Water Supply Department in Uttar Pradesh on July 1, 2023.
• About One tap -One tree scheme-
  • The scheme was launched by the Jal Shakti Minister of UP, Swatantra Dev Singh.
  • A sapling will be planted along with every new tap connection that is provided in rural areas.
  • The saplings will be planted by the Jal Shakti department and the Rural Water Supply department. 
  • The scheme is part of the government's efforts to increase the green cover in the state and to improve the water supply situation in rural areas.
  • The Jal Samitis and other organisations carried out plantation drives at district, block and gram panchayat levels.

Additional Information

• Namami Gange Programme
  • It is an Integrated Conservation Mission.
  • It is approved as ‘Flagship Programme’ by the Union Government in June 2014 with a budget outlay of Rs.20,000 Crore.
  • The main pillars of the Namami Gange Programme are:-

    • River-Front Development
    • River-Surface Cleaning
    • Bio-Diversity
    • Afforestation

  • The project ran for 30 years with an expenditure of ₹2035.56 crore and saw the development of nine full prototype engines and four core engines.

The correct answer is 'Direction of force experienced,magnetic field and current'.

Key Points

• When a current-carrying conductor is placed in an external magnetic field, the conductor experiences a force perpendicular to both the field and the current flow’s direction.
• Fleming’s left-hand rule is used to find the direction of the force acting on the current carrying conductor placed in a magnetic field.
• Fleming’s Left Hand Rule states that if we arrange our thumb, forefinger and middle finger of the left-hand perpendicular to each other, then the thumb points towards the direction of the force experienced by the conductor, the forefinger points towards the direction of the magnetic field and the middle finger points towards the direction of the electric current.

Given:

A plane in flight from Mumbai to Delhi covers a distance of 1728 km in 180 minutes.

Formula used:

Speed = Distance/Time

Calculations:

Total Time taken = 180mins = 180 × 60 sec = 10800 sec

Total distance traveled = 1728 × 1000 m = 1728000

According to the question,

Speed = (1728000)/(10800)

⇒ Speed = 17280/108 = 160 m/s

∴ The speed of the plane (in m/sec) is 160 m/s.
