Answer is [ C ]
The reason is none other than,
→ Prokaryotes are commonly referred as most primitive organisms
They lacks membrane - bound organelles , they are unicellular organisms who does not posses a true nucleus .
→ Eukaryotes are most likely advanced organisms , they posses a true nucleus & membrane - bound organelles as well. There are unicellular & multicellular eukaryotes
eg : Unicellular eukaryotes like Protists

Answer: C.Food
Explanation: In the process of photosynthesis, the chloroplasts in the cell make the food- sugar/glucose-. they do this by collecting the sunlight, water, and carbon dioxide, making the food. Any food they don't end up using is then converted to oxygen.
Answer:
c. Pyridostigmine binds to the acetylcholinesterase active site and prevents sarin from binding to and modifying the enzyme active site.
Explanation:
Sarin is a toxic compound which inhibits acetylcholinesterase enzyme. This enzyme degrades the neurotransmitter acetylcholine after the required muscle cell stimulation. In absence of its activity, acetylcholine is not degraded and the muscle cells are stimulated uncontrollably. The muscles are not able to relax which ultimately proves fatal for the victim.
Pyridostigmine is also an acetylcholinesterase inhibitor like Sarin. However its period of inhibition is short compared to organophosphorus inhibitors like sarin. It competes with sarin and replaces it in the active site of acetylcholinesterase. The enzyme is still inhibited but for a shorter time as compared to inhibition by Sarin. Hence after sometime, it becomes functional again and resumes its normal activity. Acetycholine starts getting degraded relaxing the muscles.
