Question
Which hormone regulates the body’s circadian
rhythm?Solution
Melatonin, secreted by the pineal gland, helps regulate the sleep-wake cycle (circadian rhythm).
Find the simplified value of the given expression:
{16 of 13 - 72 + √441 - (3/4) X 64} ÷ (102 ÷ 17)
√(82 × 7 × 52 - 175) = ?
{17 + √2601}/(? + 2) = 17
[5 X {(52 X 5) - 10} + 50 of 20] = ?
What will come in place of (?) in the given expression.
48 ÷ 4 + 6 × 3 - 5 = ?(? + 180 + 13 × 6) ÷ 20 + 3.5 × 512 (1/3) = 82
119 ÷ [22 - {90 ÷ (23 - 105 ÷ (7 × 3))}] = ?
12.232 + 29.98% of 539.99 = ? × 5.99
108² + 99 X 98² =?
