All living things have evolved into three groups‚ or domains‚ of closely related organisms: Archaea‚ Bacteria‚ and Eukaryota. Archaea and Bacteria are small‚ simple cells surrounded by a membrane and a cell wall‚ with a circular strand of DNA containing their genes. They do not contain a nucleus or other internal structures that higher cells may have. These are called prokaryotes. Basically all the life you see today‚ including plants and animals‚ belongs to the third domain‚ Eukaryota. Eukaryotic

The collared lizard is a species found in the Desert Southwest. Male collared lizards show considerable color variation‚ ranging from brightly colored to a very dull pattern. The goal is to determine the function‚ if any‚ of male color patterns in collared lizards‚ using the scientific method. The tentative explanation is that male color
Free Scientific method Hypothesis Natural selection
The Primordial Soup Hypothesis is a hypothesis created by Alexander Oparin in the year of 1942. It claims that life started when a group of chemicals mixed together to form a pond‚ making amino acids‚ which then lead to proteins‚ and later the first forms of life. The evidence presented in the Miller-Urey experiment provided proof that basic monomers could be created from a mixture of methane‚ ammonia‚ and hydrogen. Different to the Primordial Soup Hypothesis‚ the Iron-Sulfur World Hypothesis
