The sea was teeming with life. Eventually, through reproduction and continued variation, fish came about. There are over 20 000 species of fish, all of which have diversified over time. In this tutorial, the different factors that helped shape fish as we know them today are presented...
If the balance of nature is left untouched, landscapes can change dramatically over time. A previous ecosystem is superseded by the arrival of a newer ecosystem. This is known as ecosystem succession. Learn more about it here...
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...
Human intelligence provided the means to utilize abstract ideas and implement reasoning. This tutorial takes a further look at the brain and its capabilities of it to be used to human advantage in daily life..
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...
This lesson looks at population attributes, regulation, and growth. It also covers population genetics, particularly genetic variations, natural selection, genetic drift, genetic migration, and speciation...
