The Tyndall effect explains the phenomenon of scattering of light by the colloidal particles in its path that results in the pattern of bright glowing cones in the fluid. The Brownian Motion is related to the phenomenon of random motion of colloidal particles in the fluid. These are the widespread phenomenon that can be observed easily, but only in colloids as these properties can not be observed in True solutions or Suspension. True solutions are the homogenous mixture of two or more … [Read more...]

The main difference between these two terms is the duration, where the weather is the day-to-day or short term condition of the changes in the atmosphere, and climate is the averaged weather condition of a particular place over a long time, about 30 years. Like for instance, we talk about the weather in terms of "hot it will be today?" "Will it rain or not"? Or "What about the snowstorm this week"?. On the other hand, climate changes are observed in term of years, decades and centuries and … [Read more...]

The primary difference between them is the mechanism of immunity, where the Humoral immunity produces antibodies against the antigens which are present outside the infected cells or free circulating in the blood. Cell-mediated immunity works inside the infected cells, where it destroyed the pathogens or microorganisms by the process of lysis by the releasing cytokines. Humoral immunity shows quick response against the pathogens, while cell-mediated immunity is slow in action. Both the type … [Read more...]

Elements present to the left of the line of the periodic table are said as metals, though elements present to the far right of the periodic table are said as non-metals. Metalloids or semimetals are present just to the right of metals and possess properties of metals as well as non-metals. Hydrogen (H) is an exception, which is the first element of the periodic table and normal temperature and pressure hydrogen show the properties of nonmetal. Tin, iron, plutonium, and sodium are some of the … [Read more...]

The main points of distinction between Renewable and Non-Renewable resources are the amount at which they are used, and the rate of exhaustion, their costs, effects on the environment. Resources can be defined as available means or stock from which the individual is benefited, while natural resources are such resources which are available naturally on Earth, these can be biotic (living things) like plants, animals (their products), birds, marine organisms, mineral fuels (oil/ petroleum, coal) … [Read more...]

When the muscles of the heart contracts it is known as systolic, whereas when the heart muscles relax it is known as diastolic. At the time of systole the blood pressure increases, but at the time of diastole, the blood pressure decreases. These are the two types of blood pressure, controlled by the beating of the one's heart. The heart is the organ which provides oxygenated blood to all tissues, organs and other body parts. For pumping the blood the heart contracts and relax continuously and … [Read more...]

The first thing which clicks on one's mind while discussing plants is that they have the ability to prepare their food with the help of sunlight, water and air, along with the support of the green pigment known as chlorophyll which is found in all green plants. On the other hand, animals are known for their well-developed body and it's organ system like nervous, reproductive, digestive, respiratory, etc. Animals are also considered to be immensely susceptible or sensitive to any … [Read more...]

The small outgrowth or pouch kind of lump found beneath the skin is known as the cyst, while a tumour is an abnormal growth or mass or swelling of tissues. Identifying lump or bump under the skin area is quite disturbing, but these are not always harmful. The two most common types of lumps are cyst and tumours. Though it is difficult to differentiate them, as these are found almost in same places of the body like one can have ovarian cysts as well as ovarian tumours. With the development … [Read more...]
