Chemolithoautotroph

Explanation:

A chemolithoautotroph is an autotrophic microorganism that obtains energy by oxidizing inorganic compounds. Most chemolithotrophs are autotrophs. Examples of relevant inorganic electron donors include hydrogen, hydrogen sulfide, ferrous iron, and ammonia. Winogradsky described the concept of chemolithoautotrophy for the first time while studying the ammonia-oxidizing bacteria. Chemolithoautotrophic organisms have electron transport complexes, similar to those of chemoorganotrophs, which are used to generate a protein motive force. The proton motive force drives the synthesis of ATP. In this case, the reduction of CO2requires the use of ATP and reducing power, which is, most often, obtained through the use of the electron transport chain in reverse mode, consuming energy.

chemolithoautotroph.

Explanation: Chemolithoautotrophs are organisms that derives energy from reduced compounds of mineral origin, they utilizes inorganic molecules. chemolithoautotrophs are a type of lithotrophs with autotrophic and chemotrophic metabolic pathways. Many chemolithoautotrophs are extremophiles, but this is not true for all species.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.

she will be charged $6

step-by-step explanation:

48 dollars divided by 200 beads equals .24 dollars a bead

.24 multiplied by 25 more beads equals 6 dollars as the total cost
