Cyanobacteria can cluster together into colonies called , with some discovered in Western Australia that are 3.5 billion years old. Cyanobacteria produce oxygen and convert sunlight to energy using . Plants and arthropods didn't make the transition to land until near the end of the Period. Diverse multicellular eukaryotes didn't appear until the period. A large multicellular eukaryote requires more to survive than a single-cell eukaryote. Describe the biological chemical processes that were responsible for producing oxygen in Earth's atmosphere, eventually leading to the Cambrian Explosion. Explain the importance of oxygen in the evolution of large multicellular animal life.

The gene that causes sickle-cell disease is present in a higher percentage of residents of sub-saharan africa than among those of african descent living in the united states. even though this gene causes sickle-cell disease, it also provides some protection from malaria, a serious disease that is widespread in sub-saharan africa but absent in the united states. discuss an evolutionary process that could account for the different percentages of the sickle-cell gene among residents of the two regions.
