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.

Universal laws are the ethics that guide the behavior of humankind. These laws are universally accepted by all humans and are followed by them in their daily lives. Law of attraction, the law of vibration, is some of the examples of universal law.
Explanation:
Kant believed that telling a lie is wrong, and murdering a human is a crime. All humans should follow these two principles. Keeping in mind the words of Kant, in the given situation, I will not tell the murderer about the exact location of my friend. I will not remain silent also because that crazy man could kill me too. Instead of telling him the right directions, I will tell him the wrong directions and will send him to the wrong place so that he would not harm my friend and me. Though telling a lie is wrong but saving two lives will be more important to me in this situation.
As soon as the murderer leaves, I will call the police and will tell them the direction in which the murderer has gone. This will save me as well as my friend's life, and the murderer will also get punishment for his sin.
Hope this helps!!

Apart from Patricia's concern for her physical appearance and the weight she knows she'll likely gain as her pregnancy progresses, the dietitian will likely advice her not to gain too much weight because apart from her "physical appearance worries", gaining excessive while pregnant can also raise one's risk for birth complications such as C-section delivery and even premature birth.
In addition, the dietitian will likely offer Patricia more guidelines or tips such as:
****Commencing pregnancy at a healthy weight ( between 25 to 35 pounds), gaining more if underweight or gaining less if obese or overweight.
****Eating moderately but often, focusing on small, frequent meals that are high in lean proteins, fruits and vegetables.
****Drinking enough water ( about ten 8-ounce glasses of water) daily as this helps to aid metabolism and digestion as well as constipation prevention while preventing dehydration.
****Learning how to combine something healthy with less healthy cravings in the event of cravings for less healthy foods
**** Taking exercises such as walking very seriously as it helps to burn a great deal of excessive calories
**** Maintaining a recommended weight region at various stages of the pregnancy which will be in the best interest of mother and child
