Iron bacteria, sulfur-oxidizing bacteria, and nitrifying bacteria, which all oxidize
inorganic compounds through a series of chemical reactions, are best described as
O 1) photoheterotrophs
2) chemoheterotrophs
O 3) chemolithotrophs.
O 4) photoautotrophs
5) chemoautotrophs.
Why are salt and sugar
used in the production of dried
meat and dried fruits?
Substances that maintain a highly
hypertonic environment, like sugar and
salt, are used in the production of dried
meat, fruits or fish (for example, cod)
because the material to be conserved is
then dehydrated and the resulting
dryness prevents the growth of
populations of decomposer beings (since
these beings also lose water and die).

- Refer to the figure.

They then measured the concentrations of various metabolites immediately following the manipulation. How would these experiments help identify the CO2 acceptor? a) The CO2 acceptor concentration would decrease when either the CO2 or light is cut off. b)The CO2 acceptor concentration would decrease when the CO2 is cut off but increase when the light is cut off. c)The CO2 acceptor concentration would stay the same regardless of the CO2 or light. d)The CO2 acceptor concentration would increase when either the CO2 or light is cut off. e)The CO2 acceptor concentration would increase when the CO2 is cut off but decrease when the light is cut off.arrow_forwardSingle celled organisms that grow in irregular masses and include molds mildews and yeasts?
