The scientific and common names for Archaebacteria are both Archaea, as of 2014. Archaea used to be considered bacteria, but are now considered their own kingdom and domain separately.
Archaea are distinguished as single-celled organisms with no nucleus. They are found in a wide range of environments, including, but not limited to extreme environments, such as salt lakes, deep-sea thermal vents and hot springs. They are also found in oceans, wetlands, soil and even the human body. They reproduce asexually and do not produce spores, unlike some forms of bacteria. They are often mutualist species; but, they do not cause harm to other organisms, unlike pathogenic bacteria or parasitic fungi.Learn More

The function of the mucilaginous sheath of blue-green algae is to bind colonies together and to permit movement. The mechanism of this movement is not fully understood. The mucilaginous sheath is made of strands of cellulose and often bears pigments that give colonies of blue-green algae distinct colors.Full Answer >
Artificial embryo twinning is a method of making clones that mimics the natural process of creating identical twins, according to the Genetic Science Learning Center. It uses the same approach as natural cloning, but it is performed in a Petri dish rather than inside the mother.Full Answer >
Organisms have the ability to adapt to specific conditions within their environments through the biological process of variation, which enhance organisms' chances of survival. Variation is essentially a form of natural selection that takes place during long periods of time. Through the process of evolution, organisms retain the strongest traits and features that allow them to breed, find food, and survive in certain habitats.Full Answer >
