An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and soil), interacting as a system. These components are organisms, communities, populations, and abiotic factors. Organisms are individual living entities, while communities are groups of organisms living together in the same area. Populations are … Read more
Enzymes are biological catalysts that facilitate chemical reactions in living organisms. However, not all molecules involved in biochemical processes are enzymes. Other closely related entities include hormones, vitamins, antibodies, and cofactors. Each of these entities plays a distinct role in the human body, and it is crucial to understand their differences to accurately identify which … Read more
Ethanol, an alcohol with the chemical formula C2H5OH, exhibits a key physical property known as vapor pressure. Vapor pressure refers to the pressure exerted by the vapor of a liquid when it is in equilibrium with its liquid phase. The vapor pressure of ethanol is largely influenced by four factors: temperature, intermolecular forces, surface area, … Read more

Valence electrons in potassium (K) play a crucial role in determining its chemical properties and reactivity. The outermost electron shell of potassium contains a single valence electron, which is loosely bound and highly reactive. This valence electron is responsible for K’s low ionization energy, making it an excellent reducing agent and forming strong ionic bonds … Read more
The pH scale, a crucial tool in chemistry, owes its genesis to several notable figures. In the 1909 publication by Søren Peter Lauritz Sørensen, he coined the term “pH” and laid the groundwork for quantifying acidity and alkalinity. Building upon Sørensen’s ideas, Arnold Orville Beckman invented the first pH meter in 1934, making it easier … Read more
Reproduction is a fundamental aspect of life for protists, a diverse group of unicellular eukaryotic organisms. Protists employ a range of reproductive strategies that contribute to their ecological success and genetic diversity. Sexual reproduction, involving the fusion of gametes from two different individuals, is common among protists. This process results in offspring with a combination … Read more
