Yang, et al., Mitochondrial origins, Proceedings of the National Academy of Sciences USA 82: 4443−−4447 (1985). The first eukaryotes acquired mitochondria by endosymbiosis. In studying which living prokaryotes might be most closely related to the ancestor of mitochondria, researchers isolated and cloned nucleotide sequences from the gene that codes for the small-subunit rRNA molecule for six organisms. Cloned rRNA gene sequences for the six organisms were aligned and compared. The data table, called a comparison matrix is shown above. According to the comparison matrix, which organism is most closely related to the wheat mitochondrial gene?

The humаn bоdy's аrteriаl blооd pH is tightly maintained around 7.4 by buffering agents that bind hydrogen ions to stop any change in pH. If an acid-base imbalance overcomes the buffer system, the body changes the ventilation rate, or the rate at which gas enters or leaves the lungs. Changing the ventilation rate changes the concentration of CO2 in the blood, which alters the pH of the blood. In this case, the muscles that control the ventilation rate are acting as the:
