If carbon dioxide and water were abundantly available to a heterotrophic prokaryotic cell, would it be possible for the cell to use them as a food source? 1: sunlight would be needed for the reaction to occur, so they would not be a food source. 2: neither carbon dioxide nor water contains energy the cell could use, so they would not be a food source. 3: since carbon dioxide and water are used to make glucose, they could be used as a food source. 4: anything that contains carbon is an organic molecule, so the carbon dioxide could be a food source.

The right answer is 2.

Since the cell is heterotrophic, this means that it will not be able to synthesize glucose (energy) from CO2 and H2O, since it does not have the necessary proteins and organelles for it.

Heterotrophy is the fact that a living being is obliged to feed on organic matter: it is said to be heterotrophic. Animals, or fungi, for example, are heterotrophic.

c. would be the answer : )

explanation:

the alkaline earth metals (beryllium (be), magnesium (mg), calcium (ca), strontium (sr), barium (ba), and radium (ra)) are a group of chemical elements in the s-block of the periodic table with very similar properties: shiny. silvery-white. hopefully this ? i didn't fully understand the question
