    Vegetative Propagation is a type of asexual reproduction in which new plants form just by using some fragment of the parent plant. Artificial Method of vegetative propagation - The process of growing plants by using artificial methods is called artificial propagation. It is mainly of three types - Cutting, Budding, and Layering. (i) Cutting - In this method, a healthy young branch with a few nodes and internodes is cut off and most of its leaves are removed. Now the cut end is stuck into some good moist soil. The cutting will then develop roots, and grow into a new plant. This method is used to propagate plants like rose, sugarcane, and pineapple. (ii) Budding - In budding, a bud with a small portion of the bark is taken from the desired plant. This is inserted into a small slit that is made in the bark of the other plant. Both the plants are tied together and the buds are not allowed to dry.

    Diaphragm a barriers made of rubber That are inserted into the female reproductive tract to cover the cervix during coitus also a type of female ♀️ condom

    1Thank You

    Shreya Singh 4 years, 6 months ago

    The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm relaxes and returns to its domelike shape, and air is forced out of the lungs.
