Plant Metabolism
Plants are responsible for incredible feats of molecular transformation. Plant processes, such as photosynthesis, photophosphorylation, chemiosmosis, carbon fixing reactions, respiration, are presented in this tutorial...
Physiological Homeostasis
Homeostasis is essential to maintain conditions within the tolerable limits. Otherwise, the body will fail to function properly. The body does this through feedback control mechanisms, e.g. blood sugar level regulation and temperature regulation. Read this tutorial to know more about the principles of negative feedback control employed by the body to sustain homeostasis...
Animal Water Regulation
Animals adapt to their environment in aspects of anatomy, physiology, and behavior. This tutorial will help you understand how animals adapt to their habitat. For instance, how animals thrive in aquatic habitat and are able to overcome osmosis. It also sheds light on the reasons animals adapt...
The Human Nervous System
The nervous system is essentially a biological information highway. This tutorial gives an overview of the nervous system, most especially its cellular features. Recognize the cellular composition of this biological system through this tutorial...
Growth and Plant Hormones
Plants, like animals, produce hormones to regulate plant activities, including growth. They need these hormones to respond well to their environment and to sustain growth, development, and dispersal. Plant biologists recognize five major groups of plant hormones: auxins, gibberellins, ethylene, cytokinins, and abscisic acid. Find out in this guide the importance of each hormone in the life of a plant...
Consciousness and Behavior
Human consciousness and behavior are an interesting topic since they are determined and controlled by the brain. Consciousness can be defined by behavior or by electrical pattern of brain activity. Read this tutorial to learn about brain activities, such as sleep, attention, emotion, motivation, consciousness disorders, learning, and memory...
