DNA double helix

DNA is the genetic material that provides our cells with all the information they need to build proteins and other compounds that are necessary to keep ourselves and our cells alive. In some species, strands of DNA code for over 100,000 genes.

Abiotic Factors
Abiotic Factors

The Earth has a number of environmental variables, such as temperature, wind exposure, rainfall, sunlight and nutrient availability that make life on Earth possible. These environmental variables are known as abiotic factors and they control the range of environmental conditions in a given area.


Making their home in the cracks of your driveway: mosses, hornworts and liverworts. Bryophytes are seedless, fruitless, non-vascular plants and have found their way into the moist environments all around the globe.

Rocky shore ecosystems

Rocky shore ecosystems are governed by the tidal movement of water and have diverse communities from the high tide to below the low tide line. The ecosystems of the rocky shore have a characteristic banding of different species which are influenced by the biotic and abiotic factors from above high tide to the sub-tidal zone.

Roots: A life underground

When plants evolved from marine species and made their way onto land they had to overcome many challenges to survive and thrive on land. The evolution of an underground root system has enable plants to collect water and nutrients and helped to make it possible for land based plants to diversify into the 1000s of species currently present on Earth.

Mammalian skeleton

The mammalian skeleton can be separated into the axial and appendicular skeletons. The axial skeleton consists of the skull, spinal column and rib cage and the appendicular includes the bones of the arms, legs, hands, feet, pelvis and shoulder.
