ts. They use this energy to build organic molecules from carbon obtained from the carbon dioxide in seawater. These bacteria are _____.

They use this energy to build organic molecules from carbon obtained from the carbon dioxide in seawater. These bacteria are _____. See Concept 27.3 (Page 579) chemoautotrophs photoautotrophs chemoheterotrophs photoheterotrophs
Since these bacteria obtain energy by the oxidation of electron donors (inorganic hydrogen sulfide) in their environments (chemical reactions) we can classify them as chemotrophs. In addition, they synthesize all necessary organic compounds from CO2 so they are autotrophs (opposite from heterotrophs that are unable to fix carbon).
They both carry a recessive allele for blue eyes because answer A doesnt state anything about the allele dominance, answer B wouldnt be right because if blue eyes was dominant then the mother would have blue eyes as the dominant gene always shows, but she has brown
Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. When the information stored in our DNA? is converted into instructions for making proteins? or other molecules, it is called gene expression
