Digestion - breaking down food into simpler forms. Digestion is both and chemical . The digestion may take place outside cells ( extracellular ) or within the cells ( intracellular ). Absorption - Taking in of food in the soluble forms into the tissues. The absorption may be passive (without ..
Energy
Energy can be defined as the ability to do work. A good source of energy would be the one which would: do a large amount of work per unit volume or mass be easily accessible be easy to store and transport and be economical Fossil Fuel Fossil fuel is a hydrocarbon de..

We can see many situations in which energy is transferred to or from objects and systems, similar to money being transferred between accounts. In each situation, we assume that the energy that was involved can be accounted for, that is, energy cannot appear or disappea..

Mechanism
A low-dose x-ray source moves in an arc (360 o ) around a specific part of the body being scanned and repeatedly sends out x-ray beams. As the beams pass through the body, the tissues absorb small amounts of radiation. Once the beam passes through, they are converted by light sensitive c..
Mechanical work and heat
If we rub our hands for a while, the hands become warm. Let us examine the process. Rubbing hands is mechanical work and in this process heat is generated. We can say heat energy is produced as a result of mechanical work. Let us examine another example - when you ligh..

The process of electrolysis is exactly opposite to one that takes place in a voltaic cell. A voltaic cell or a battery uses its chemical energy to produce electrical energy. While in electrolysis, electrical energy is used to bring about a chemical change. Humphrey Dav..
Carrier mechanism
In carrier mechanism, activated ions combine with carrier proteins and from ion carrier complex. This complex moves across the membrane and reaches the inner space by the expenditure of energy. Within the cytoplasm, the complex breaks to release the ions. The carrier moves out o..

Although matter circulates, energy cannot be reused indefinitely. Solar energy is converted by the photosynthetic producers (plants) into chemical energy in the form of plant carbohydrates. Herbivores consume the plant carbohydrates and so this chemical ..

Tutor was excellent, asnwered the question rapidly and provided the information I needed to understand the problem.
This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
Best tutor ever. I can actually understand what to do in fraction and decimal division situations
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.
