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.
Answer:
Both the nervous and endocrine system
Explanation:
The endocrine system works together with the nervous system to influence many aspects of human behaviour, including growth, reproduction, and metabolism.
Answer:
because they have seeds while others don't
Explanation:
The answer to this question would be: decrease, decrease
Anorexia is a mental disease that causes the patient to experience fear of gaining weight. In this case, the patient will try to limit their food intake(in an extreme way) or induce vomit to remove the food.
The effect should be same as starvation or malnutrition. As the food intake decreased, blood glucose is decreased too. The body adapts by lowering the basal metabolic rate so it loses less energy. Insulin and leptin will be decreased too as it was not needed.
