The correct answer is: chemoautotrophs

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).

What is the minimum pH difference such that transfer of one H ion across the membrane would provide enough energy to make one mo
Studentka2010 [4]

Answer:

The minimum difference is already the value of 1

Explanation:

When the pH is not balanced between the extracellular and intracellular environment, the cell could go into shock, that is why in the face of the minimal differences in pH between the internal or external environment, the proton pump is activated, this is how the hydrogen ion or positively charged protons cross the membrane and indirectly generate ATP molecules.

Plant reproduction by tissue culture differs from reproduction by meristem culture because
Leviafan [203]

The answer is; B

Meristem cells are totipotent meaning they can differentiate to any type of plant cells. Therefore they can produce a variety of plant type depending on epigenetic. However, tissue culture is derived from already differentiated cells. Therefore these cells are already determined and can only produce cell type of that plant from which they were derived.

what would be the most likely effect on cellular respiration if a plant were to lose much of its cjhlorophylkl
goldenfox [79]

Cellular respiration would produce less energy when plant were to lose much of its chlorophyll.

Plants can actually live longer without photosynthesis than they can without respiration. Some plants survive half the year without performing photosynthesis, but if they stop performing cellular respiration, even for a minute, they would be dead where they stand.

During photosynthesis, plants absorb sunlight and carbon dioxide from the air. Through a series of steps, much like cellular respiration, they convert these reactants into the products oxygen and glucose. The plants then can use the oxygen and glucose to make ATP in cellular respiration. The rate of respiration is greater than the rate of photosynthesis. So this means there is an overall excess of carbon dioxide is produced during respiration.
