This tutorial presents the benefits and the possible adverse eventualities of genetic engineering. Know more about this topic in this tutorial to be able to articulate the advantages and disadvantages of artificially manipulating genes...
Plants need to regulate water in order to stay upright and structurally stable. Find out the different evolutionary adaptations of plants in terms of structure (e.g. stomata) and physiological mechanisms (e.g. root pressure, capillarity, transpiration pull, curving of leaves, etc.) that enabled them to maintain the appropriate water level...
The gastrointestinal system breaks down particles of ingested food into molecular forms by enzymes through digestion and then transferred to the internal environment by absorption. Find out more about these processes carried out by the gastrointestinal system through this tutorial...
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...
