Question Discussion & Solution

Eagle, Bird, Crocodile

All Eagle is the Bird and Crocodile is the reptile. 

So,  Venn diagram given bellow-

Hence, option 4 is the correct answer.

The pattern followed here is:

Similarly,

Hence, ODVKOGHMQ is the correct answer.

Concept:

• Plant growth hormones or phytohormones are simple molecules with complex chemical composition, that regulates the growth and physiology of plants.
• Based on their functions on the living plant body they can be classified into two groups:

1. Plant growth promoters - Promotes activities like cell division, cell enlargement, flowering, fruiting, etc. Eg. Auxins, Gibberellins & cytokinins.
2. Plant growth inhibitors - They are involved in various growth-inhibiting activities like dormancy, and abscission. Eg. Abscisic acid.

• Gaseous PGR like ethylene can be put into both groups, however, it is largely an inhibitor of growth activities.

Explanation:

• Ethylene is a simple gaseous PGR.
• It is synthesized in large amounts by tissues undergoing senescence and ripening fruits.
• Influences of ethylene on plants include horizontal growth of seedlings, swelling of the axis, and apical hook formation in dicot seedlings.
• Ethylene promotes senescence and abscission of plant organs, especially of leaves and flowers.
• Ethylene is highly effective in fruit ripening. It enhances the respiration rate during the ripening of the fruits. This rise in the rate of respiration is called respiratory climactic.
• Ethylene breaks seed and bud dormancy, initiates germination in peanut seeds, sprouting of potato tubers.
• Ethylene promotes rapid internode/petiole elongation in deepwater rice plants.
• It helps leaves/ upper parts of the shoot to remain above water.
• Ethylene also promotes root growth and root hair formation, thus helping the plants to increase their absorption surface.

Additional Information

Concept:

Meaning of i++:

First, we read the i than after reading the value of i we are going to increment i this is nothing but post-increment.

Meaning of ++i: 

First, we increment i than we read the value of I, this is nothing but pre-increment:

Examine code:

int main( )
{
int i = 10;
int C = i++;   // assign i to C therefore C = 10 after assigning increment i by 1
printf("i = %d, C =  %d", i, C);
return 0;
}

Output:

i = 11, C =  10

Therefore value of i to be assigned to C, and then I to be incremented by 1

The correct answer is option 4.

Explanation:

• Compact Disc-Recordable (CD-R) technology is known as Write Once-Read Many (WORM), which allows you to write data onto a disk just once that can not be erased.
• CD-R discs are blank CDs that can record data written by a CD burner. After that, the data is permanent and can be read any number of times. ​

Additional Information

• The data burned onto a CD-R disc is permanent.

• CD-RW Stands for "Compact Disc Re-Writable."
  • A CD-RW is a blank CD that can be written to by a CD burner. 
  • CD-RW can be written multiple times.
• CD-ROM Stands for "Compact Disc Read-Only Memory."
  • A CD-ROM is a CD that can be read by a computer with an optical drive. 

• ​Another term of Worm (termed as 'malware') A computer worm is a malicious virus, that is a self-replicating software program that affects the functions of hardware and software programs.​​
