Introduction Kingdom Animalia is a group of eukaryotic, multicellular organisms with a heterotrophic mode of nutrition. Animals lack cell walls in their cell structure and they are usually motile Animals have different structures and forms but there are some characteristic features similar in various individuals based on the arrangement of cells, symmetry, coelom, digestive and circulatory systems. These features are used to classify animals for better understanding Classification of Animal kingdoms based on their characteristic Animals do not show a similar pattern of cells as all individuals are multicellular. The classification of animals is based on the organization of ... Read More

Introduction Husbandry, derived from the word husband, means managing carefully used regarding a household or a farm, but today it is used in agriculture or cultivation of plants as well as animals. Animal Husbandry is a largely scaled business where animals are sheltered, bred, and reared, cared for, in specially built regions for profitable purposes, such as the animals which provide us food and other products. Animal husbandry includes livestock, poultry farming, fisheries and beekeeping.Poultry farming is a type of livestock breeding for domestic birds such as ducks, and chickens to produce food which mainly includes meat and eggs. To ... Read More

Introduction A human body contains trillions of cells, and are the fundamental units of living organisms that give structure to the body. Cells communicate with each other through cell-cell adhesion or via extracellular matrix through cell adhesion molecules. A group of cells specialised in one or more similar functions is termed tissue. They form organs like skin, kidney, lungs, liver, and heart and an organ system comprises two or more organs that have the same functions. These all share their work and contribute to the survival of the entire body. What are the different Types of Animal Tissue? The animal ... Read More

Introduction Anatomy is the identification and description of the structure of an organism. It is a field of biology and medicine which plays an important role in medical education and research. Anatomy is the oldest scientific discipline of medicine, whose origin relates to the ancient Greeks thousands of years ago. A systematic study of anatomy was initiated by the Greek scientists Arcmeon and Empedocles and the former was the first person to have an autopsy on the human body. Erasistratus and Herophilos first practised the human anatomy of convicted criminals, so they conducted the first scientific research to discover how ... Read More

Introduction The organic compounds that contain both the carboxyl and amino groups are Amino acids. So there are two functional groups present in this molecule they are amino (-NH2) and carboxyl groups (-COOH). Amino acid is a short form of the word alpha-amino carboxylic acid. Amino acids contain the elements- carbon, oxygen, nitrogen, and hydrogen. But in some amino acids, other elements such as sulphur and selenium are also present. Amino acids are the basic constituent of proteins. And proteins are formed when amino acids combine. Protein has many uses in the human body as well as in other organisms. ... Read More

Introduction Drugs are any substances that interact with the macromolecules present inside the body and create a physiological and psychological response. It can be administered through various routes such as ingestion, inhalation, intravenous, and smoldering. The prolonged regular use of alcohol and drugs leads to drug addiction and subsequently drug dependency, which causes several issues for both the individual and society. It affects the central nervous system of the human body and it can cause risk to the entire body because drug components transmit improper signals to various body segments. As a result, drug use should be restricted, and medications ... Read More

Introduction Agriculture is the art and scientific study of the development and cultivation of the soil, developing yields and raising animals. Over centuries, human survival has been dependent on agriculture and farming. The growth of farming and agriculture contributed to the rise of civilization. What is agriculture? Agriculture is defined as a practice of plant and livestock cultivation to obtain desired products for human use. In agriculture, there are certain criteria to be viewed such as the kind of crop, properties of soil, environment and so on. Depending on these criteria, farmers conclude which crop is to be developed at ... Read More

Introduction Agriculture is the art of cultivation of crops and animal farming. Seed plays a major role in the production of desirable foods to fulfil the increasing demand of the population. It is a small fertilised part of a plant, made up of embryo, endosperm, and seed coat that can grow into new individual plants by seed germination. The good quality of seeds can reduce replanting, increase uniformity, and promote early growth of crops, therefore the essential step in agriculture is the selection of good quality seeds. The production of high-yielding and quality crops is maximised by applying agricultural practices. ... Read More

Introduction Energy is necessary to all the cells of the body to facilitate various metabolism, therefore every living organism involves cellular respiration to release energy, which is stored in the form of ATP. Food is moved into the stomach through the oesophagus after intake and it breaks into various smaller pieces including glucose by stomach acids and enzymes. Glucose is the most abundant monosaccharide and is an initial substrate for carbohydrate metabolism, and it is broken down to release energy, therefore glucose and ATP are the energy-carrying molecules. Definition of Cellular Respiration Cellular respiration is the energy-producing process that occurs ... Read More

Introduction All living organisms can produce new individuals like themselves and their cells have a nucleus containing chromosomes. In humans, there are 23 pairs of chromosomes, each chromosome has thousands of genes. A gene can carry the information that determines the character or trait being transmitted from the parent to offspring and creates the identity of an individual. Some traits are not received from the parents because the information about traits is not carried by genes. i.e, not encoded in DNA. These are non-heritable and acquired when the individual has an injury, disease, repeated activities, or other environmental influences. It ... Read More
