Vegetative Propagation.
Vegetative propagation is technique through which plants reproduction takes place in an asexual way. This is usually done by cutting a stem of a plant and to reproduce another plant from the existing one. This can also be done via sexual means.
The advantages of growing of fruits and vegetables by using vegetative propagation are many. The biggest benefit is if we have a plant of a desirable trait, that same plant can be used again and again to reproduce fruits and vegetables. Vegetative propagation is also treated as cloning method.
Answer:
Precession
Explanation:
Various stars will act as northern stars due to precession, as well as the stars and planets arrayed around the celestial equator (zodiac) will steadily change locations. Every 73 years, they move around one degree. For the remainder of our days, and for a few millennia later, Polaris would stay the North Star.
A change in the core would have the greatest effect on the convection currents in the mantle. Hope this helped!
