Girth of stem increases due to (a) apical meristem (b) lateral meristem (c) intercalary meristem (d) vertical meristem

Apical meristem is present at the growing tips of stems and roots. Their main function is to initiate growth in new cells of seedlings, at the tip of roots, and...

Here, r = 4. 2/ 2  m = 2.1 m, h = 4.5 m  (i) Curved surface area of the storage tank = 2πrh  = 2 × 22 7 × 2.1 × 4.5...

Here, h = 5 cm, 2πrh = 94.2 cm2.  (i) 2πrh = 94.2  ⇒ 2 × 3.14 × r × 5 = 94.2  ⇒ r = 94. 2/ 2x 3.14x 5 = 3  Hence, base...

Ye kya kiya hai I don't understand

Informal communication is known as grapevine. This is because informal communication spreads throughout the organisation in all directions without following the formal path of communication.

(x+2)2 = x2 + 102 x2 + 4x + 4 = x2 + 100 => 4x + 4 = 100 => x = 24 Depth of the pond = 24m

(a) increases if the average refractive index increases

(d) varies in a way that depends on the actual value of A.

(c) remains the same

c. the cell division of meristems are faster than the rate of viral multiplication
