Carbohydrates

Carbohydrates are macronutrients and are one of the three main ways by which our body obtains its energy. They are called carbohydrates as they comprise of carbon, hydrogen, and oxygen at their chemical level. Carbohydrates are essential nutrients which include sugars, fibers, and starches. They are found in grains, vegetables, fruits, and in milk products. […]


Air, Water And Soil Pollution

The presence of extremely high concentrations of harmful substances in the environment is known as pollution. The major kinds of pollution causing health hazard today are air, water, and soil pollution. When certain human activities pollute environmental media such as air, water or soil such that they are harmful to the health of living organisms […]


Forest Biodiversity and Ecosystem

The ecosystem, biomes, biodiversity, and species or population interaction in such communities are an important aspect of Biology. Forest is a large geographical area dominated by trees, animals of various species, aquatic biomes and microorganisms. Study of forest and its various aspects becomes imperative if you want to learn about the biological interaction of species […]


Mendelian Genetics

Mendelian Genetics is a kind of biological inheritance that highlights the laws proposed by Gregor Mendel in 1866 and rediscovered in 1900. These laws faced a few controversies initially but when Mendel’s theories got integrated with the chromosome theory of inheritance, they soon became the heart of classical genetics. Later, Ronald Fisher combined these ideas […]


Reproductive System

Reproduction is the process by which organisms produce their offspring and the set of organs required for this process is called the reproductive system. Every other organ in the human body is identical in shape and function both in males and females except the organs of the reproductive system. Males and females have a different […]


Gasses: We Breathe In and Breathe Out

The air which we breathe in and breathe out is not pure oxygen or carbon dioxide respectively. As we all knew that our body and the cells inside it requires more oxygen to respire and to perform its regular functions and our environment does not provide us with an exclusive supply of oxygen. In a […]


Taxonomical Aids

Taxonomical aids are the collections of samples or preserved organisms which help in extensive research for the identification of various taxonomic hierarchy. Classifying organisms into various categories needs a lot of field and laboratory study. This is so important because taxonomic categorization helps in identifying many organisms necessary in various fields like agriculture, industries, bioresources, […]


Proteins

We often see bodybuilders and physical trainer drinking whey protein along with milk to build-up metabolism and strength.When it comes to our body, our hair and nails are mostly made of proteins. Basically, proteins are the fundamental building blocks of our body. They are large and complex macromolecules or bio-molecules which perform a major role […]


Diseases – Types of Diseases an…

The disease is a condition which deteriorates the normal functioning of the body cells, tissues, and organs. Based on certain signs and symptoms, it is categorized as non–communicable and communicable diseases. Below listed are some common diseases with their symptoms. Types of Diseases Acquired Diseases They are acquired after the birth. They are grouped into […]


Spermatogenesis

Spermatogenesis is a process by which the male gametes, known as sperm is formed. In this process, each sperm is haploid, containing a single copy of each chromosome.In order to create the haploid gamete, a cell undergoes the process of meiosis in which the genome is replicated and divided twice to produce four haploid gametes. […]
