6. Grafting is a technique used to increase the numbers of a particular variety of plant. A stem cutting,
from a commercially grown fruit tree, P was grafted onto the roots of a non commercial tree Q.
a) What is the type of reproduction shown in this process?
b)
If the new tree bears fruits, which variety will the fruits would be produced-commercial or
non-commercial? Why?
c) List three ways to ensure that grafting in the above case is successful?

Answer:
a. When an object falls freely to the ground, it is under the effect of a constant force known as force of gravity. No other forces act on it. Hence, from Newton's second law of motion, we can say that this constant force of gravity accelerates the the freely opposite, their effects do not get cancelled because these action and reaction forces do not act on the body. ball has s ball than a cricket ball moving with the same velocity.
b. Even though the magnitudes of action force and reaction force are equal and their directions are opposite, their effects do not get
cancelled.
c. It is easier to stop a tennis ball as compared to a cricket ball, when
both are travelling with the same velocity.
d. The velocity of an object at rest is considered to be uniform...
