Answer:

There was no sulfur compound added to the medium, that could be used as an electron donor.

Explanation:

Bacteria that use light for energy requirements mean that they get their energy from photosynthesis and transferring energy through the molecules.

Bacteria play a major part in the reductive and oxidative cycle of the sulfur which is mediated by the help of photosynthetic bacteria, so the sulfur or sulfur compounds are major requirements for their growth in the habitat or the medium.

Thus, the correct answer would be- There was no sulfur compound added to the medium, that could be used as an electron donor.

(hi, i dont know about this one personally, but i found an answer somewhere else on the internet thatll hopefully help u)

Answer: They consist of long chains of C, H, and O.

Explanation:

In terms of chemical composition, lipids differ from nucleic acids and proteins because they mostly just contain carbon, hydrogen, and oxygen (except for phospholipids which of course contain phosphorous). In addition to those elements, proteins contain nitrogen and sulfur, and nucleic acids contain nitrogen and phosphorous.

Carbohydrates share the C, H, and O composition as lipids, but they differ in structure. Lipids are generally exist as triglycerides, which consist of a triple hydroxyl alcohol (glycerol) that has bonded to three long-chain carboxylic acids (fatty acids) in a triple condensation reaction. Carbohydrates on the other hand are made of carbon ring structures that either remain alone or polymerize into long polysaccharide chains.
