Conduction is the movement of heat through a substance by the collision of molecules. It occurs when two object at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature.

Complementary angles are those whose sum is 90.

Given here, is a right angled triangle, where anfle C is 90 deg. In this, sum of Angles A + C = 90, since, sum of angles in a right angled triangle = 180, angle C = 90 and

hence sum of A + B = 180 - C = 180 - 90 = 90.

Hence, the pair of cimplementary angles in the given triangle = Angle A + B.

TRUE, the compounds are formed as a result of chemical change.

Plants developing in dry conditions are called as xerophytes.

Tensional forces normally cause normal faults.

The basic concept in economics is that all resources are limited.

The repeating units that are used to form the helical DNA structure are called nucleotides.
