Such changes which do not produces any new substances after the reaction is called as the physical change, whereas the changes which bring out the formation of new substance is named as the chemical change. So we can say that the main difference lies in the chemical composition, where one (chemical change) of the change is involved in altering the composition of the material and thus forms new substance and the other (physical change) brings out alteration in size, shape and colour … [Read more...]

Even the cytoplasm consists of the organelles like mitochondria, Golgi body, endoplasmic reticulum, etc., on the other hand, protoplasm consists of the cytoplasm, nucleus, and the plasma membrane. Although, both cytoplasm and protoplasm contain the same chemical constituents such as salts, proteins, and water. The above … [Read more...]

Cells make tissues and tissues make an organ, and different organs present in the body make an organ system. The tissue is capable of performing the simple task while organs are known for operating the complex one. Though the size of the organ is greater than the tissue and requires more energy to perform any function. Living organisms have great diversity, whether living in water or land, but shares the essential component in common that is 'the cell'. Being the primary part of every life, … [Read more...]

T cells and B cells differ in their functions, like T cells are known to develop various immune response such as invading bacteria from body's immune system, virus attacks, not supporting the organ transplant, etc., while B cells produce antibodies against the antigen. Despite showing variance in their working, T and B cells struggle with the same aim of destroying the invader or foreign particles which are harmful to the body. Our body's immune system is supported by many essential cells, … [Read more...]

In the Celsius scale, the boiling point of water is 100°C, and the freezing point is at 0°C, while in the Fahrenheit scale the boiling point of water is measured at 212°F and freezing point at 32°C. This is the significant point which distinguishes both. Although there are other factors, which make them different from each other like the matter of acceptance. As due to the easily right property, Celsius is used all over the world, except in the United States, as they use Fahrenheit as their … [Read more...]

Voluntary muscles or striated muscles are those which work according to the one's desire or are under control, whereas Involuntary muscles are not under one's control.

Locomotion and movement are the main features of the organisms, whether it is unicellular or … [Read more...]

CT Scan uses harmful x-rays ( the form of electromagnetic radiation like light) for imaging, while MRI does not use any radiation and is based on the effect of the magnetic field, radio waves for the imaging of the organs of the body. CT Scan gives the images of the bones in a much-sophisticated way than the x-ray and is good to check the fractures, tumors, and arthritis but MRI which is popular in detecting the damage of soft tissue. It is also seen that CT Scan is not as expensive as the … [Read more...]
