In soil, there may be found 3 types of reactions. They are neutral, alkaline, or acidic reactions. The measure of the chemical reaction of soil(degree of alkalinity or acidity) is expressed by its pH value. Soil pH Soil pH is the negative logarithm of the concentration of hydrogen ion (expressed …

Plants can see us. They can monitor their visible environment. They can see if you’re wearing a red or blue shirt. They know if you’re moving them from one place of your house to another. When you take a picture turning the flash on for a better and clearer image, …

In a Museum when you see a glittering crystal, you would say it was a mineral  and you’d almost certainly be right. But can you say what a mineral really is? Define Minerals A mineral is an inorganic solid which is naturally occured. It has a fixed chemical composition and …

Vitamins and minerals are essential nutrients because they perform many roles within the body. There is a fine line between getting enough of those nutrients (which is healthy) and getting an excessive amount of (which can find yourself harming us). Eating a healthy diet remains the best way to get …

Globular and fibrous proteins A protein whose molecules curl up into a ‘ball’ shape, such as myoglobin or hemoglobin, is known as a globular protein. In a living organism, proteins may be found in cells and in other aqueous environments such as blood, tissue fluid and in phloem of plants. …

Units of work Whenever a new quantity is introduced in physics, the standard metric units associated with that quantity are discussed. In the case of work (and also energy), the standard metric unit is the Joule (abbreviated J). One Joule is equivalent to one Newton of force causing a displacement of one meter. …

The study of the flow of warmth or the other sort of energy into or out of a system because it undergoes a physical or chemical transformation, is named Thermodynamics. In other word relationship between heat, work, temperature, and energy. In broad terms, thermodynamics deals with the transfer of energy from one place to a different and from one form to a …

Carbohydrates are fundamentally the sugars, starches and fibers found in fruits, grains, vegetables and milk products. Though often it slander in trendy diets, carbohydrates which is one of the basic food groups which are important to a healthy diet. A carbohydrate is a biomolecule containing of carbon (C), hydrogen (H) and oxygen (O) atoms, normally with …

Bacteria (singular: bacterium) are classified as prokaryotes. They are single-celled life/body with a simple core-less internal structure and contain DNA that swims freely in a twisted, thread-like matter called a nucleoid, or in circular parts called plasmids. Bacteria are single-celled microscopic life/organisms that grow in different environments, and these organisms can live in …

Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells, and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which …
