Question Discussion & Solution

Concept

The javac command in Java compiles a program from a command prompt.

It reads a Java source program from a text file and creates a compiled Java class file.

Syntax

javac filename [options]

For example, to compile a program named Abc.java, use this command:

javac Abc.java

Key Points

• Gramin Gaurav Path is a major road construction program started by the state Government of Rajasthan and is implemented by Public Works Department (PWD). 
• Under the Gramin Gaurav Path project, the government aims to construct main Gram Panchayat roads in 33 districts in the Rajasthan state. 
• In the first phase, the government planned to construct 1720 km of roads in the 1972 gram panchayat.
• In the second phase, the government plan to construct 2098 km of roads in 2086 gram panchayat.
• The government has aims to construct roads in all villages that come under the main gram panchayat for hassle-free transport for villagers.  

Important Points

• The main objective of the Gramin Gaurav Path Scheme is to construct a Cement Concrete road and proper drainage at each Gram Panchayat headquarters with the purpose of creating a neat and clean environment.
• The program also aims to provide damage-free roads for commuters at each Gram Panchayat Headquarters.
• Rural villagers now easily travel to schools, hospitals, temples, farms, nearby villages, and towns because of the construction of good roads. 
• The Rajasthan government has approved Rs 1,115 crore for the Gramin Gaurav Path program

Additional Information

• It covers 342,239 square kilometres or 10.4 per cent of India's total geographical area. 
• It is the largest Indian state by area and the seventh-largest by population
• Area: 342,239 km²
• Governor: Kalraj Mishra
• Capital: Jaipur 
• Population: 6.89 crores 
• Chief minister: Ashok Gehlot

The correct answer is Bone-marrow.

Key Points

Red blood cell:

• Red blood cells (RBCs) are the most common type of blood cell and the vertebrate's principal means of delivering oxygen to the body tissues via blood flow through the circulatory system.
• RBC is formed in Bone Marrow.
• RBCs take up oxygen in the lungs, or in fish the gills, and release it into tissues while squeezing through the body's capillaries.
• The cytoplasm of erythrocytes is rich in hemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the red color of the cells and the blood.
• Each human red blood cell contains approximately 270 million of these hemoglobin molecules.
• The cell membrane is composed of proteins and lipids, and this structure provides properties essential for physiological cell function such as deformability and stability while traversing the circulatory system and specifically the capillary network.

Additional Information

• Red blood cells are thus much more common than the other blood particles: there are about 4,000–11,000 white blood cells and about 150,000 - 400,000 platelets per microliter.
• Human red blood cells take on average 60 seconds to complete one cycle of circulation.
• The blood's red color is due to the spectral properties of the hemic iron ions in hemoglobin.
• Each hemoglobin molecule carries four heme groups; hemoglobin constitutes about a third of the total cell volume.
• The normal pH range of blood is between 7.35 to 7.45. This means that blood is naturally slightly alkaline or basic.

The correct answer is Sulphur.

• The sulphur is the eye irritating compound that is released when cutting onions.
• The syn-Propanethial-S-oxide is the chemical irritant produced by an onion.
• This chemical stimulates the eyes' lachrymal glands which release tears.
• Previously scientists used to blame enzyme alinase for the instability of substances in a cut onion.
• In 2002, a study in Japan proved that lachrymatory factor synthase is responsible for irritation of the eyes.

Anish walked 100 m towards north.

He then took a U-turn and walked 100 m.

Now he took a U-turn again and walked 102 m.

From here he turned left and walked 93 m.

Anish facing west direction.

Hence, option 2 is the correct answer.
