Layering
In this technique roots are induced on a stem before it is detached from the parent plant. In layering, the lower branch close to the ground is bent down and covered with moist soil. After some days roots develop from the branch, which can be cut and grown independently. The 2 i..
Application to Switching Circuits
Application to Switching Circuits - The application of Boolean algebra to electronic devices such as computers, lies in the restriction of the variable to two possible condition 'On and Off' or 'True or False' or numerically '1 or 0'. The electric circuits carry out the Boolean ..

2. Programmed senescence theory
According to this theory, ageing is the result of the sequential switching on and off of certain given, with senescence. T- lymphocytes or B - lymphocytes have the receptors for self-antigens by which they undergo programmed cell death or apoptosis, thus reducing their numbe..
Logical 'AND' Operation
Let us refer to a circuit consisting of two switches p and q connected in series with a lamp and battery as shown in figure. The lamp will glow, only if switch p and switch q are closed. If we replace the word 'closed' by T and 'open' by F, the switch..

This is my favorite tutoring ever. i might say that to others to, but this tutoring has thought me the most from any tutorings!! -Ashlyn
I uploaded a worksheet and I wanted to follow it with the tutor so I could learn the technical parts. It took just a few minutes to get the understanding of what I needed with the tutor. I even get through all the examples on the sheet in 25 minutes that we were focused on it.
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
