The answer is the first choice
Answer:
Option A, accumulate sulfur as intracellular granules.
Explanation:
Purple sulfur bacteria belong to the group of Proteobacteria. These probacterias are anaerobic in nature and yet are able to photosynthesise. They are usually found in water environments such as hot springs, stagnant water etc. They use sulphur (either in the form of sulfide, or thiosulfate) as an electron donor in their photosynthetic activity to oxidise sulfur thereby producing granules of elemental sulfur.
while filamentous sulfur oxidizers use nitrate instead of oxygen to oxidize sulfide thereby producing granules.
Hence, option A is correct.

You need amino acids for vital processes such as building proteins, hormones, and neurotransmitters.
Amino acids are concentrated in protein-rich foods such as;
- meat,
- fish
- egg
- soybeans, etc
<h3>What are calories?</h3>
Calorie is a unit of energy. This derived from eating energy giving foods.
Excess calories in the body is often store d as fat.
Thus, the outcome of amino acids if someone overeats protein and calories in general is "the amino acids are stored as fat".
