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...]
Difference Between Evergreen and Deciduous Forests
The critical and the common distinction between the two types of forests is the in 'Evergreen forests' as the name says the trees do not shed their leaves in any season, until and unless they are old which are soon replaced by the others. On the other hand, 'Deciduous forests' shed their leaves in the dry season to save the water loss. Evergreen Forests are found in the area which receives more than 200 cm of rainfall annually, while Deciduous Forests grow in the area receiving annual … [Read more...]
Difference Between Humoral and Cell-Mediated Immunity
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...]
Difference Between Metals, Non-Metals and Metalloids
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...]
Difference Between Breathing and Respiration
Breathing is the biophysical process which involves the inhaling and exhaling of air through lungs, whereas respiration is the biochemical process which involves in generating the energy by breaking down the glucose which is further used by cells in various function. Breathing is distinct from respiration in many ways, though both are essential for living organisms. As discussed above the mechanism of breathing is associated with the respiratory organs like the nose, lungs, etc., while … [Read more...]
Difference Between Endotoxin and Exotoxin
Endotoxins are the Lipopolysaccharide-protein complexes (LPS), responsible for making an integral part of the cell wall of Gram-Negative Bacteria and are released at the time of cell death or lysis of bacteria. Exotoxins are the proteins which are secreted by few species of bacteria and get diffuse into the nearby or surrounding medium. Secondly, endotoxins are heat stable, weakly immunogenic while exotoxins are heat labile, highly antigenic. Endotoxins are produced by Gram-negative bacteria, … [Read more...]
Difference Between Photosystem I and Photosystem II
The two main multi-subunit membrane protein complexes differ in their absorbing wavelength, where the photosystem I or PS 1 absorbs the longer wavelength of light which is 700 nm while photosystem II or PS 2 absorbs the shorter wavelength of light 680 nm. Secondly, each photosystem is replenished by the electrons, after the loss of an electron, but the sources are different where PS II gets it electrons from water while PS I gains electrons from the PS II through an electron transport … [Read more...]
Difference Between Stems and Roots
The part of the plant which is present above the surface of the soil is called Stems, while Roots is the part of the plant which is present below the soil surface. Secondly stems arises from the plumule and roots from the radical of the embryo. Most importantly stems possess leaves, but roots do not. A common flowering plant (vascular plants) possess a well-defined root and shoot system. These are an essential part of the plant and bears many morphological and anatomical differences. Though … [Read more...]
Difference Between True Solution, Colloidal Solution, and Suspension
The true solution is the homogenous mixture, while Colloidal solution and Suspension are the heterogeneous mixtures of two or more substances. Another difference between these three types of solution is that the True solution is transparent, while the Colloidal solution is translucent and Suspension is opaque. Concerning chemistry, Solutions can be defined as the mixtures of two or more substances, where the solvent is in the liquid form, and the solute can be liquid, solid or gas. There are … [Read more...]
Difference Between Rods and Cones
Rods and Cones are the photoreceptors, useful in providing vision to the eyes. Rods provide vision during dim light or night also known as scotopic vision, whereas cones provide vision during day time or at bright light also known as photopic vision. Secondly, rods do not support the colour vision, but cones are capable of colour vision, with high spatial acuity — the level of the light where both the types of work, is called a mesopic vision. Eyes are one of the primary sense organs found … [Read more...]
