Answered by dibyasakhandai30

Answer:

Stimulus - It is a change in the physical or chemical structure of an organism's internal or external environment

The plant responds to many types of external stimuli such as light, gravity, weather, and touch. The response of a plant is either positive (grow towards the stimulus) or negative (grow away from the stimulus). For example, phototropism is the plant's response to stimulus, i.e. sunlight.

Example 6 : Find the LCM and HCF of 6 and 20 by the prime factorisation Solution: We have : 6 = 21 x 31 and 20 = 2 x 2 x 5 = 22 x 51 You can find HCF(6, 20) = 2 and LCM6, 20) = 2 x 2 x 3 x 5 = 60, as done in earlier classes. Note that HCF(6, 20) = 21 = Product of the smallest power of each com prime factor in the numbers. LCM (6, 20) = 22 x 31 x 51 = Product of the greatest power of each prime...
