Stromatolites (pictured here) are rocky structures that generally form in shallow waters from the binding of sediment by microbi
al biofilms. Stromatolites are typically hypothesized to be formed from the presence of cells that bind these grains together. If the appearance of the stromatolites in the fossil record were to indicate the emergence of life on earth, which cell types would most likely be responsible for their formation? A) Prokaryotic cells B) Eukaryotic yeast cells C) Eukaryotic plant cells D) Eukaryotic animal cells
Coffin-Lowry syndrome is caused by changes (mutations) in the RPS6KA3 gene and is inherited in an X-linked dominant pattern. Males are usually more severely affected than females.
