Types of Food Chains
There are mainly two types of food chains operating in nature. a) Grazing food chain b) Detritus food chain. Grazing food chain is generally seen in ecosystems such as grassland, pond or lake where a substantial part of the net primary production is grazed on by herbivores (cattle and rod..

Active absorption
This process is much faster and requires energy. A membrane pump operates across the cell membranes which transports the nutrients from the lumen of the intestine into the cells. This transport occurs with the help of ATP molecules. The carrier proteins in the membrane act as ATPases and..

A two valued Boolean algebra is defined on a set of two elements B = {0, 1}, with rules for + and . as shown in the following tables. These rules are exactly the same as the AND, OR and NOT operations..

A set A is said to be a proper subset of set B if A is a subset of B and A is not equal to B. If A is a proper subset of B, then we write A B. In order to show that A B it is sufficient to show that each element of A is in B and there is at least one element in B, which is not i..

. This is the auricular systole. This impulse is generated and spread by the presence of electrochemical gradient. The impulse is carried to atrio ventricular node that is situated almost at the junction of the auricles and the ventricles. It then transmits it to the other nerves of the heart. The ..

This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor Vista tutor helped me understand and gave me some practices and showed me how to do them.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
Tutor Vista tutors are pleasant and great to work with, they were very patient and explained everything that is simple to follow. I love working with them. - John Coakley
