Introduction Evolution is an intricate and slow process. Various organisms constantly adapt by changing their morphological and anatomical characteristics in response to the change in the environmental conditions of their habitat. They make minor changes in their genetic composition to adapt to their surroundings and thrive in their niche. These, minor alterations in their genes […]
Introduction All plants and animals depend on other plants or animals to survive. A example might be a lion consuming a deer or a deer feeding on shrub leaves. In order to depict how energy and nutrients travel through an ecosystem, food chains and food webs were created. In addition to helping us understand the […]
Introduction Environmental changes are natural and will continue to occur from time to time. Change can be abrupt or gradual, like climate change and global warming. Because of the changing environment, some creatures become extinct while certain species can thrive with very minor alterations. These modifications are passed down across generations, enabling the species to […]
Introduction All species, whether they have one cell or many, engage in diverse metabolic processes. The body produces harmful chemicals as a result of these processes. To prevent excessive accumulation of these waste products in the body, they must be excreted. The excretory system of the body performs the function of eliminating waste. Different species […]
Introduction Mammals, fish, amphibians, birds, and reptiles are among the five classes into which animals are divided. Each one of them needs the environment to survive, including air, food, water, and shelter. The only vertebrates that live part of their lives in water and part on land are amphibians. As a result, they differ from […]
Introduction Apiculture is the practice of culturing honey bees on a bigger scale to yield beeswax and honey. It is a scientific approach to rear the bees in man-made hives, raising their numbers and caring for them. Beekeepers or apiarists are those who practice apiculture. Man-made beehives are artificial bee hives. These are made of […]
Introduction The word ‘amnio’ (Greek in origin) means inner membrane around the foetus and ‘centesis’ means to prick i.e. amniocentesis refers to the procedure of obtaining amniotic fluid by making a tiny puncture in the inner membrane surrounding the foetus. It is a prenatal test which is carried out before or during pregnancy. Amniocentesis is […]
Introduction A metabolic pathway consists of a series of chemical reactions in which a certain molecule is transformed from one product to another. Enzymes catalyze each step in a metabolic pathway. The anabolic pathway involves biosynthesis, or the creation of new molecules, and is a constructive mechanism. On the other hand, the catabolic pathway is […]
Introduction Human Anatomy is the discipline of science that focuses on the structural composition of humans. It is a Greek word wherein “ana” is (up) and “tome” is (cutting). Anatomy is the study of how the human body is arranged and made up of cells, tissues, organs, and organ systems. Human physiology is a branch […]
