self introduction why

Process of covering the flower or inflorescence by paper covers in order to avoid fertilization by external pollen. This makes only self pollination possib..

You are what you think you are. Our self-image is often based on what others make us believe we are. A poor self-image can do irreparable damage to us. Think of a frog, and immediately, you are reminded of its croaking. Think of a nightingale and its melodious voice comes to..

Self Induction - When a current is established in a conductor, a magnetic field is produced in its vicinity. We can visualize this field in terms of magnetic flux. If steady current flows the number of lines of force at a given place would remain the same. But if the current changes with ..

It is the transference of the pollen grains from the anther to the stigma of either the same or of another flower borne on the same pla..

It can recognise and respond to molecules that are foreign or 'non-self'. It can also avoid response to molecules that are part of the body or 'self' of the anim..

In some plants even if self pollination takes place, fertilisation is prevented as the pollen fail to germinate. Such plants can produce seeds only after cross pollination. E.g., Brassi..

Self Duplication and Survival - Living organisms do not survive indefinitely. Every organism dies after attaining a certain age or due to predation, disease, accident or other factors. The reduction in the number of individuals of a population as a result of death, is restored by the addi..

If we consider a plane coil of radius r through which a current I ampere is flowing. If N is the number of turns of the coil, magnetic field at the center of the coil. Magnetic flux per turn of the coil = BA Total magnetic flux linked with N turns But f = L..

Living organisms do not survive indefinitely. Every organism dies after attaining a certain age or due to predation, disease, accident or other factors. The reduction in the number of individuals of a population as a result of death, is restored by the addition of new individuals by a process calle..
