Largest single-celled organism found on earth!

October 23, 2011 · 1 Comment · Adaptations, biodiversity, Cell biology

What do you think is the largest single cell on earth? Remember there are limits to the size of cells due to absorption of nutrients and oxygen and release of wastes. How does a cell bigger than a cricket ball manage these limits? Where do you think you would find such an organism? These strange […]

10: Physiological Adaptations for Survival

June 19, 2011 · 1 Comment · Adaptations, Functioning Organisms

Learning Intention: Students will develop an understanding of the terms and definitions used and how physiological adaptations allow organisms to survive in their environment. Success Criteria: Students will be able to describe a range of physiological adaptations and how those adaptations allow organsims to survive in their environment. Adaptations to an organism’s environment can usually […]

Image Source Tonight on ABC1 you may have been lucky enough to watch “Life” narrated by David Attenborough. This, the first of three episodes, was about fish – their variety, feeding and reproductive behaviours, habitats and predators.  It began with footage taken in southern Australian waters, of the weedy sea dragon, showing how the male […]

Physiological Adaptations to cold temperatures

July 14, 2010 · No Comments · Adaptations, Functioning Organisms, Student Posts

Image Source – Cold-tolerant Wood Frog Wood frogs (Rana sylvatica) are found in the northern parts of North America where the temperature can get very cold. When the wood frog experiences chilly conditions, a chemical signal is sent through it’s boy which prepares the frog to be frozen. The frog can remain frozen solid for […]

Physiological adaptations for Survival

July 12, 2010 · No Comments · Adaptations, Functioning Organisms, Student Posts

Budgerigars – Melopsittacus undulatus The following posts are by students, about the structual, functional and behavioural features of vertebrates that live in arid environments, that enable them to balance their water requirements. Structural -Small size of the budgie means that the water requirements are minimal. -Budgerigars save water by excreting thier waste as nitrogenous waste. […]

Water brings changes

October 12, 2009 · No Comments · Adaptations, biodiversity, Functioning Organisms

You might think that providing water in arid areas would allow native species to flourish, as well as the stock it is intended to supply. However, sinking bores and providing tanks or troughs allows larger predators of native species access to areas that previously they found too dry to survive in. Small, native marsupials have […]
